DESCRIPTION
Refer to specific data sheets for flow capacities and vacuum capacities.
N NOTE: Refer to diagrams in this manual for proper rotation and orientation in inlet and discharge.
Tuthill Vacuum & Blower Systems model 1200 rotary lobe blowers are positive displacement type blowers, whose pumping capacity is determined by size, operating speed, and differential pressure conditions. Blowers employ rotors rotating in opposite directions within a housing closed at the ends by end plates.
The inlet to the discharge is sealed with operating clearances that are very small. Internal lubrication is not needed, as there is no moving contact.
Clearances between the rotors during rotation are maintained by a pair of accurately machined helical timing gears, mounted on the two shafts extended outside the air chamber. The intermeshing rotary lobes are designed to rotate and trap air or gas between each rotor and the housing. As the rotor lobes rotate past the edge of the suction port, the trapped air or gas is essentially at suction pressure and temperature. Since the blower is a constant volume device, the trapped air remains at suction pressure until the leading rotor lobe opens into the discharge port. The close clearances between the rotors inhibit back slippage of the trapped volume from between the rotors and the trapped volume is forced into the discharge piping. Compression occurs not internal to the blower but by the amount of restriction, either downstream of the blower discharge port or upstream of the blower inlet port.
6
Figure 4-1 illustrates the air movement within the machine. The air moves not between the rotors but between the rotors and the side of the housing.
Also, the machine is bi-directional, meaning that the direction of rotation of the blower can make either side the inlet or discharge. Also, see Figure
4-2 on page 7 .
Never attempt to control capacity by means of a throttle valve in the intake or discharge piping. This will increase the power load on the drive system, will increase operating temperatures, and can overload and/or seriously damage the blower. Likewise, if a possibility exists that flow to the blower inlet may be cut off during normal operation of a process, install an adequate vacuum relief valve near the blower.
A pressure-type relief valve in the discharge line near the blower is also recommended for protection against cutoff or blocking in this line. Use check valves on each blower when more than one blower is connected to a discharge line.
When a belt drive is used, it is possible to adjust blower speed to obtain the desired capacity by changing the diameter of one or both sheaves, or by using a variable-speed motor pulley. In a directcoupled arrangement, a variable-speed motor or transmission is required, or excess air or gas may be blown off through a manually controlled unloading valve and silencer. Gas units can use bypasses, but some applications may require additional cooling. If there is a large volume of high-pressure air or gas downstream of the blower, a check valve in the piping downstream of the blower will protect the blower from overspeeding in a backward direction upon shutdown.
Consult a Tuthill Vacuum & Blower Systems sales professional if questions arise.

To permit continued satisfactory performance, a blower must be operated within certain approved limiting conditions. The manufacturer’s warranty is, of course, also contingent on such operation.
Maximum limits for pressure, temperature, and speed are specified in Table 4-2 on page 8 for various blower sizes when operated under the standard atmospheric conditions. Do not exceed any of these limits.
Specially ordered blowers with nonstandard construction, or with rotor end clearances greater than shown in Assembly Clearances
on page 40, will not have the operating limits specified here. Contact your
Tuthill Vacuum & Blower Systems sales representative for specific information.
Special attention must be paid when a blower has a higher than standard ambient suction temperature. Special recommendations for operating parameters and/or additional cooling may be recommended. Consult the factory or local representative for appropriate information.

INSTALLATION
GENERAL
!
DANGER
The blower is not intended to be used with explosive products or in explosive environments. The blower is not intended to be used in applications that include hazardous and toxic gases. Consult the factory for support.
!
DANGER
It is the responsibility of the installer to assure that proper guarding is in place and compliant with all applicable regulatory requirements.
!
WARNING
The bare shaft blower can generate excessive noise.
Methods to reduce the noise levels by installing inlet and outlet silencers will be required.
Even with inlet and outlet silencers, hearing protection will be required.
!
WARNING
Customers are warned to provide adequate protection, warning and safety equipment necessary to protect personnel against hazards in the installation and operation of this equipment in the system or facility.
!
WARNING
The standard MAWP is per Table 4-2. The
MAWP shall not be exceeded unless specific factory testing of the pressure containing components of the blower has been performed.
!
WARNING
Table 4-2 states the maximum operating speed in RPM (rotations per minute) and maximum temperature. Do not exceed these limits. The installation of the booster shall take these critical operating parameters into account and adequate control features implemented.
10 Operator’s Manual 2009 Rev B p/n 2009
!
WARNING
Upon completion of the installation, and before applying power, rotate the drive shaft by hand. It must move freely. If it does not, look for uneven mounting, piping strain, excessive belt tension or coupling misalignment or any other cause of binding.
If blower is removed and still does not move freely, check inside the blower housing for foreign material.
Remove the protective covers from the shaft and inspect for damage.
Carefully check to ensure that no transit damage has been sustained. If damage has occurred from shipment a claim must be filed with the carrier immediately; preserve the shipping container for inspection by the carrier.
In the event that your unit sustains damage while being shipped to your facility, do not return it to the factory without first obtaining shipping instructions from us.
Do not remove protective covers and plugs until the connection is being made. Mount the blower on a flat, level surface. Use a baseplate that is a rigid, solidly supported, and structurally sound. Shim under the legs where necessary so that each leg of the blower supports an equal share of the blower weight. This is necessary to prevent eventual twisting of the blower. Make sure feet rest evenly on the mounting surface before fastening down.
Twisting or cramping the blower during mounting will cause rotor contact and binding during operation, resulting in a condition called “soft foot.”
See Soft Foot on page 13 for further details and preventative measures.
A blower that is factory-mounted on a base should not require such adjustments. However, since the assembly can become twisted in shipping or installation, check for soft foot after installing the base. Shims may be needed for alignment. Loosen
Operator’s Manual 2009 Rev B p/n 2009
05
Installation the foot hold-down screws to check foot contact with the mounting surface. Mount the base on a solid foundation or heavy flooring, using shims as necessary at bolting points to prevent warping the assembly. See Foundation on page 12 for more information.
Transmission of small operating vibrations to a support structure may be objectionable in some cases. Use of vibration isolators or vibration absorbing materials can be effective in overcoming this transmission. To avoid casing distortion, apply the treatment under the common motor/blower base or mounting plate rather than directly under the feet alone.
Make sure piping is accurately squared with the blower and supported independently. Stress imparted from incorrectly aligned piping or mounting will create problems with bearing and seal life, possibly leading to premature internal contact. The blower should sit stress-free and evenly on its supporting surface. Take care to evenly tighten the mounting bolts to avoid imparting undue stress into the blower. Stress can be checked in a free state with feeler stock or verified on a previously installed blower with the aid of a dial indicator. Spring or gap should be found less than 0.002 in. (0.05 mm).
Use only clean, new pipe and make certain it is free of scale, cuttings, weld beads, dirt, or any other foreign material. To guard against damage to the blower, make sure an inlet filter is used. Clean the filter of collected debris after a few hours of operation and periodically thereafter. See Piping
Connections on page 18 for additional details.
Figure 5-1 shows a typical complete installation of blower and accessories. Note the absence of throttle or shut-off valves in both discharge and intake piping. If it is possible for air flow to be cut off in either line, add a pressure and/or vacuum relief valve. In some installations, it may be desirable to use only an inlet silencer-cleaner supported directly from the blower connection. Keep the weight of accessories and piping to a minimum to prevent blower casing distortion. If the weight exceeds
10% of blower weight, support the components independently of the blower and connect them with a flexible hose or connectors. The approximate weights of the blowers are listed in Table 4-1 on page 8 and Table 4-2 on page 8 .

A blower may be driven by direct-coupling to the driver or by V-belt drive for the purpose of obtaining other speeds within the approved range. See Motor Drives on page 20 for more information.
Blowers from Tuthill Vacuum & Blower Systems are internally and externally treated after factory assembly and testing to protect against rusting in normal atmospheric conditions prior to installation.
The maximum period of internal protection is considered to be up to 6 months under average conditions, provided closing plugs and seals are not removed. Protection against chemical or saltwater atmosphere is not provided. Avoid opening the blower until ready to begin installation, as protection will be quickly lost due to evaporation.
For recommended preparations for long-term storage (longer than 6 months), see Long-Term
Storage on page 31 .
12
Location
Install the blower in a room or outdoor area that supplies adequate space and lighting for routine maintenance. Make sure indoor installation areas are well ventilated and kept as cool as possible, because operating the blower at elevated temperatures can result in nuisance overload or temperature shutdowns. An unprotected outdoor installation is satisfactory only when correct lubrication for expected temperatures is provided.
See Recommended Lubricants on page 42 .
Foundation
The blower does not need a special foundation.
However, it does require a solid, level floor and adequate frame support. Bolt the blower system to the floor, and seal any cracks.
Blower Air Intake
To minimize maintenance, supply the blower with the cleanest air possible. The air must not contain any flammable or toxic gases, as the blower will concentrate these gases. This could result in damage to the blower and surrounding property, and could lead to personal injury or death. Do not block or restrict the opening of the blower and/or motor, as they could overheat and fail.
Do not use blowers on explosive or hazardous gases. Do not exceed the limits described in
Table 4-2 on page 8 . Each size blower has limits on performance criteria such as pressure differential, running speed, and discharge temperature.
If it is necessary to take air from a remote source, such as in a vacuum application, make sure the diameter of the piping is at least equal to the diameter of the blower inlet. For distances greater than 20 ft (6 m), enlarge the pipe diameter to reduce inlet restriction. Excessive restriction will reduce the efficiency of the blower and elevate its discharge temperature. The piping used should also be corrosion-resistant and free of scale and dirt. Keep the inlet covered to keep out precipitation, insects, and small animals. Vacuum kits are available.
Operator’s Manual 2009 Rev B p/n 2009
Soft Foot
Soft foot is a condition in which one of the blower feet does not sit flat on the base. Soft foot is usually due to irregularities in the surface to which the blower is mounted. When the bolt on the foot is tightened, a slight distortion occurs that can affect bearing and seal life as well as cause premature internal contact between the rotors and the housing.

SAFETY
Tuthill Vacuum & Blower Systems recommends the use of relief valves to protect against excessive pressure or vacuum conditions. Test these valves at initial start-up to be sure they are properly adjusted to relieve at or below the maximum pressure differential rating of the blower.
!
DANGER
It is the responsibility of the installer to assure that proper guarding is in place and compliant with all applicable regulatory requirements.
PARALLEL
SOFT FOOT
Figure 5-2 – Illustrations of Soft Foot
1. Place the blower on the base.
2. Check each foot for gaps between the foot and base (soft foot). Shim as necessary to fill gap within 0.002 in. (0.05 mm).
Figure 5-2 shows the two most common types of soft foot conditions. If either type is present at a measurement of more than 0.003 in.
(0.076 mm), the blower may fail prematurely.
3. Tighten all bolts.
4. Mount a dial indicator on the base contacting one foot at 12 o’clock position.
5. Loosen the bolt on that foot. Observe indicator travel and add shims as needed to reduce
“spring” to less than 0.002 in. (0.05 mm).
Repeat steps 4 and 5 on the remaining feet.
!
DANGER
Internal and external rotating parts of the blower and driving equipment can produce serious physical injuries. The blower should never be run with the inlet or discharge piping removed. If it becomes necessary to inspect the rotating parts of the blower or to change V-belts, be absolutely sure that all power to the motor controls has been shut off, the motor controls are locked out, and properly tagged before proceeding.

!
DANGER
Assure that properly sized vacuum breaks/ relief valves are used on the inlet side of the blower. Also assure that properly sized pressure relief valves are used on the outlet of the blower. The sizing shall be such to assure that the proper flow can be achieved without exceeding the rated vacuum and pressure ratings.
!
DANGER
Blower housing and associated piping or accessories may become hot enough to cause major skin burns on contact.
!
WARNING
Use lock out/tag out procedures to disable the electrical energy source before any service or work is done on the blower.
!
WARNING
Avoid extended exposure in close proximity to machinery with high intensity noise levels.
Wear adequate ear protection.
N NTEE: Use proper care and good procedures in handling, lifting, installing, operating, and maintaining the equipment.

Installation
The end cover oil reservoirs are connected together by passageways external to the rotor housing. To change oil, drain from the one-inch square head plug located in bottom of cover, or the on-half inch plug in the oil pump cover.
Check oil levels frequently. Shut down the blower to properly check oil level.
Frequently Asked Questions Regarding
Lubrication
What is the functional detriment if the “wrong oil” is used?
The lubricant is selected based on bearing speed, gear speed, and operating temperature.
If the lubricant is too light, it increases wear by not separating the sliding surfaces and it will not remove the heat adequately. If the lubricant is too thick, the drag in the bearings is increased, causing them to run hotter. Thicker lubricant will not flow as readily into the gears and it will reduce the available backlash. Lubricants at our conditions are incompressible.
What is the functional detriment if the oil is not serviced?
If the lubricant is not serviced at the proper interval, the shearing action in the bearing and the gears will begin to take its toll and the lubricant will thicken. The blower will run hotter and the wear on moving parts will increase. The lubricant will generally appear dirtier, caused by material rubbing off the components. The lubricant will discolor because of overheating. An indicator of the breakdown of a lubricant is the increase in the TAN
(Total Acid Number), and a change of 10 percent in the base viscosity.
Several things are happening as the lubricant goes through the blower. First, it is absorbing frictional energy in the form of heat. This heat has to be dissipated through either surface contact with cooler materials or in a rest volume of lubricant. While reducing the friction, the lubricant is also going through a shearing process and the molecular structure is broken down.
The result is that the lubricant will begin to thicken because of the shorter molecular chains and the drop out of additive packages. The thickened lubricant will cause more drag, increasing the friction and heat, and further degrading the lubricant.
Operation of the blower (environment, run time, speed, and pressure) has a direct effect on duty cycles. The published cycles are based on worstcase conditions.

Recommended Oil Change Intervals
Use Table 5-1 as an approximate guide. For best results, Tuthill Vacuum & Blower Systems recommends an oil sampling program.
The initial oil change should occur after the first
200 hours of operation. Thereafter, frequency of oil changes will depend on the operating conditions.
Check for oil contamination periodically. Time between oil changes should never exceed 6 months.
In addition, see Recommended Lubricants on page 42 .

Oil Filter
Change the oil filter element and its shell gasket at every oil change. The oil filter element (P/N
91999-1) and shell gasket (P/H 12102-6) are available from Tuthill Vacuum & Blower Systems in Springfield, Missouri, or from any authorized distributor or service center.
!
CAUTION
Factory-supplied filters are engineered to provide the proper restriction in the oil lubrication system. Using filters other than those available from Tuthill Vacuum & Blower
Systems may result in lubrication problems and possibly unwarrantable damage to the booster.

Installation
Oil Pressure Adjustment
The oil pressure on each blower has been preset at the factory during the load testing. The oil pressure should not require adjustment once the blower is installed and in operation. However, in rare cases, some adjustment may be needed due to speed and oil temperature. The oil pump itself has no adjustment. The oil bypass relief valve located in the oil feed line after the oil filter can be used for the same purpose.
To adjust the blower to the proper oil pressure:
1. Remove the hex cap shown in Figure 5-4 .
2. Loosen the lock nut.
3. Turn the set screw clockwise to increase the pressure or counterclockwise to decrease the pressure.
4. Tighten the lock nut and replace the cap.
5. Read the oil pressure. Oil pressure may vary between 5 psig (34 kPa) and 30 psig (207 kPa). The blower’s oil system can operate satisfactorily at 1 psig (6.9 kPa), if necessary, and still have sufficient flow. Always allow the blower to reach operating temperature before adjusting the oil pressure to the proper range.
Set the oil pressure to 15 psig (103 kPa).

Oil Cooler
All versions are supplied with four-pass coolers.
Either hole can be used for water inlet with no effect on performance. For most applications,
2-5 gpm (7.5-20 L/min) of 60°F (15°C) water is sufficient. Actual water usage will depend on operating conditions. Ideal oil temperature is
140-160°F (60-72°C).
All standard coolers are designed for use with fresh water only. Do not use brackish or salt water. The liquid to be cooled (oil) flows around the tubes and the cooling liquid (water) flows through the tubes.
!
WARNING
If the unit is to be located outside or in a building where ambient temperatures can fall below freezing, then care must be taken to ensure the water or liquid used for cooling does not freeze and damage the booster.
Nil cooler must be drained of liquid during downtime unless a re-circulating unit using a glycol mixture has been installed.
PIPING CONNECTIONS
!
WARNING
Pipe loading on the blower should be negligible as pipe loading can cause distortion of the blower. Use proper supports and pipe hangers to assure that there is no loading.
Remove the protective covers from the inlet and outlet ports and inspect for dirt and foreign material.
18 Operator’s Manual 2009 Rev B p/n 2009
If the blower is to be located outdoors or in a building where the temperature surrounding the blower or the water supply and return piping can fall below 35°F (2°C), then care must be taken to ensure that the water (or other cooling liquid) does not freeze and cause damage. Heat exchanger and cooling lines must be drained of liquid during downtime unless a recirculating unit using a glycol mixture has been installed.
Units are never shipped from the manufacturer with liquid in the heat exchanger or cooling lines.
Inlet and outlet connections on all blowers are large enough to handle maximum volume with minimum friction loss. Maintain same-diameter piping. Do not support silencers by the blower.
Avoid stress loads and bending moments.
Be certain all piping is clean internally before connecting to the blower. Place a 16-mesh wire screen backed with hardware cloth at or near the inlet connections for the first 50 hours of use until the system is clean. Clean the screen after a few hours of operation and completely discard it once the system is clean, as it will eventually deteriorate and small pieces going into the blower can cause serious damage. A horizontal or vertical airflow piping configuration is easily achieved by rearranging the mounting feet position.

Hazards Associated With Hazardous
Process Fluids
!
DANGER
It shall be the responsibility of the installer to ensure that piping is adequate, sealing between pipe joints is adequate for the process fluids and proper process and pressure protection devices are in place.
It is also the responsibility of the installer to assure that process gasses are not vented in a manner that would be hazardous.
Refer to the manufacturer of the process media to assure that proper safety precautions are in place.
Blockage or Restriction
!
WARNING
Damage to the blower could occur if there is blockage in the inlet or outlet ports or piping.
Care should be taken when installing the blower to assure that there are no foreign objects or restrictions in the ports or piping.
Operator’s Manual 2009 Rev B p/n 2009 19
05
Installation
MOTOR DRIVES
Two drive connections commonly used are direct drive and V-belt drive.
Direct Coupled
When installing the motor directly to the blower, align the shafts to the coupling according to the coupling manufacturer’s instructions. Blowers shipped with motor directly coupled and mounted on a common base have been aligned prior to shipment. Further alignment is normally not necessary, but be sure to check the alignment if necessary prior to starting the blower.
Coupling halves must correctly fit the blower and drive shafts so that only light tapping is required to install each half. The two shafts must be accurately aligned. A direct-coupled blower and motor must be aligned with the two shafts not having more than
0.005 in. (13 mm) Total Indicator Reading (T.I.R.).
Make sure the face is aligned within 0.002 in.
(0.05 mm).
Establish proper gap between coupling halves according to coupling manufacturer’s instructions with the motor armature. Proper gap will minimize the chance for end thrust on the blower shaft. Realign and grease all direct-coupled base-mounted blowers after field installation.
V-Belts
If the motor and blower are V-belt connected, the sheaves on both the motor and blower shafts should be as close to the shaft bearings as possible. Blower sheave is not more than 1/4 in.
(6.5 mm) from the blower drive end cover. The drive sheave is as close to the driver bearing as possible. Take care when installing sheaves on the blower and motor shafts. Make sure the face is accurately in line to minimize belt wear.
20
Adjust the belt tension to the manufacturer’s specifications using a belt tension tester. Check new belts for proper tension after 24 hours of run time.
When manufacturer data is not available, industry guidelines are 1/64 in. deflection for each inch of span (0.157 mm per centimeter of span) at 8 – 10 lb
(3.6 – 4.5 kg) of force in the center of the belt.
Insufficient tensioning is often indicated by slipping
(squealing) at start-up. Do not use belt dressing on V-belts. Keep sheaves and V-belts free of oil and grease. Remove tension from belts if the drive is to be inactive for an extended period of time. For more specific information, consult the drive manufacturer. In a V-belt drive, the blower sheave must fit its shaft accurately, run true, and be mounted as close to the bearing housing as possible to minimize bearing loads.
A tight or driving fit will force the drive shaft out of its normal position and cause internal damage. A loose fit will result in shaft damage or breaking.
Make sure the motor sheave fits correctly and is properly aligned with the blower sheave.
Adjust the motor position on its sliding base so that belt tension is in accordance with the drive manufacturer’s instructions. Always avoid excessive belt tension. Recheck tension after the first 10 hours of operation and periodically thereafter to avoid slippage and loss of blower speed.
Check blower after installation and before applying power by rotating the drive shaft by hand. If it does not rotate freely:
• Look for uneven mounting, piping strain, excessive belt tension, or coupling misalignment.
• Check the blower to make sure oil was added to the reservoirs.
Setting V-Belt Tension
Proper belt tension is essential to long blower life. Figure 5-5 , Figure 5-6 , and the following procedure are provided to aid in field-adjusting
V-belts (when the blower is so equipped) for maximum performance. A visual inspection of the
V-belt drive should yield the appearance shown in
Figure 5-5 .

Factors outside the control of the belt tensioning system used on an individual blower package assembly, such as environmental factors and quality of the belts installed, may contribute to decreased belt life. Such factors can cause wear of the belts beyond the ability of the tensioning system to compensate.
05
Installation
As such, it is recommended to check belt tension monthly and make any manual adjustments found necessary.
1. Turn off and lock out power.
2. Remove the fasteners from the belt guard (if equipped).
3. Remove the belt guard.
4. Check and adjust the belt tension as necessary. Tension should be 1/64 in. deflection per inch of span (0.157 mm deflection per centimeter of span) between sheaves, with 8 – 10 lb (3.6 – 4.5 kg) force applied at the center point of the top section of the belt.
5. Install the belt guard, making sure that all drive components are free of contact with the guard.
6. Install the belt guard fasteners that were removed in step 2.
7. Unlock the power and start the blower.
8. Resume normal operation.

OPERATION
GENERAL
!
!
DANGER
The blower is not intended to be used with explosive products or in explosive environments. The blower is not intended to be used in applications that include hazardous and toxic gases. Consult the factory for support.
WARNING
Do not operate without guards in place.
!
WARNING
Maximum operating speed: Table 4-2 states the maximum operating speed in RPM
(rotations per minute), the maximum pressure differential, maximum vacuum and maximum temperature rise. Do not exceed these limits.
Before starting the blower for the first time under power, recheck the installation thoroughly to reduce the likelihood of difficulties. Use the following checklist as a guide, but also consider any other special conditions in your installation.
1. Be certain no bolts, rags, or dirt have been left in the blower.
2. Be certain that inlet piping is free of debris. If an open outdoor air intake is used, be sure the opening is clean and protected by an inlet filter.
This also applies to indoor use.
3. If installation is not recent, check blower leveling, drive alignment, belt tension, and tightness of all mounting bolts.
4. Be certain the proper volume of oil is in the oil reservoir chambers.
5. Be certain the driving motor is properly lubricated and that it is connected through suitable electrical overload devices.
6. With electrical power off and locked out to prevent accidental starting, rotate the blower shaft several times by hand to make sure the blower is rotating freely. Unevenness or tight spots are indicators of a condition that should be corrected before progressing.
7. Check motor rotation by momentarily pushing the START button and then checking the flow direction of the blower. Reverse the motor connections if flow is in the wrong direction.
24 Operator’s Manual 2009 Rev B p/n 2009
06
Operation
Carry out initial operation under “no load” conditions by opening all valves and venting the discharge to atmosphere, if possible. Then, start the motor briefly, listen for unusual noises, and make sure the blower coasts freely to a stop. If no problem appears, repeat this check and let the motor run slightly longer. If any questions exist, investigate before proceeding.
Assuming all tests are satisfactory, the blower will now be ready for continuous full-load operation.
During the first several days, check periodically to make sure all conditions remain acceptable and steady. These checks may be particularly important if the blower is part of a process system where conditions may vary. At the first opportunity, stop the blower and clean or remove the inlet filter.
Also, recheck leveling, coupling alignment or belt tension, and mountlng bolts for tightness.
START-UP CHECKLIST
It is recommended that these start-up procedures be followed in sequence and checked off ( ) in the boxes provided in any of the following cases.
• During initial installation
• After any shutdown period
DATES
CHECKED:
• After maintenance work has been performed
• After blower has been moved to a new location
Check the unit for proper lubrication. Proper oil level is critical. See Lubrication on page
14 . See Recommended Lubricants on page 42 for information on acceptable lubricants for the product.
Check the V-belt drive for proper belt alignment and tension.
Carefully turn the rotors by hand to be certain they do not bind.
!
WARNING
Disconnect power. Make certain power is off and locked out before touching any rotating element of the blower, motor, or drive components.
“Bump” the unit with the motor to check rotation (counterclockwise when facing the shaft) and to be certain it turns freely and smoothly.
Start the unit and operate it for 30 minutes at no load. During this time, feel the cylinder for hot spots. If minor hot spots occur, see Troubleshooting on page 38.
Apply the load and observe the operation of the unit for 1 hour.
If minor malfunctions occur, discontinue operation and see Troubleshooting on page
38 .

Operation
OPERATING
The upper temperature limit for blower operation is 400°F (205°C), measured in the exhaust gas stream with a low-mass thermocouple. When this temperature limit switch is installed, as the temperature exceeds the predetermined temperature, the blower motor will stop and cannot be restarted until the temperature drops below the trip setting of the temperature switch.
!
DANGER
The blower is not intended to be used with explosive products or in explosive environments. The blower is not intended to be used in applications that include hazardous and toxic gases. Consult the factory for support. Gas application units must be fully approved by the Tuthill factory prior to the purchase of the product and must be designed specifically for the gas application.
!
WARNING
Physical harm may occur if human body parts are in contact or exposed to the process vacuum. Assure that all connections are protected from human contact.
!
WARNING
If rated vacuum or pressure levels are exceeded, process fluids will migrate to other parts of the blower and system.
!
WARNING
The blower can generate excessive noise, hearing protection is required while the unit is in operation.
!
CAUTION
Do not touch hot surfaces.
The upper limit of the blower operation is 400º F (205º C). Do not touch the blower while it is in operation and assure blower is cool when not in operation.
!
CAUTION
Use of a thermowell insulates the thermocouple. Invalid and delayed readings will result. This can result in ineffective protection devices.
The upper temperature limits are not intended for continuous operation. Consult with factory for detailed information assistance.
STOPPING
!
CAUTION
Do not stop the blower if there are high outlet pressures in the outlet piping. Unload the outlet piping prior to shutting down the blower.
Stop the blower by turning off the motor. Isolate the blower from the vacuum system, and vent the blower to atmosphere. Turn off the cooling water if the blower is water cooled. Stop the backing pump.
See the component instruction manual.
26 Operator’s Manual 2009 Rev B p/n 2009
WATER-INJECTED BLOWERS
Water injected into the inlet of a blower operating on vacuum service will cool the blower. The water absorbs the heat of compression as it passes through the blower along with the air/gas being compressed. A blower cooled in this manner can operate safely at higher vacuums or higher inlet temperatures than a normally uncooled blower.
The amount of water required depends on the inlet air/gas temperature, inlet vacuum, water temperature, and maximum discharge temperature desired. Check with the factory or sales representative for additional guidance.
Operation
1. Check the oil level in the sight glass of the blower and make sure all fittings are tight.
2. Check the water injection system to make sure water is available.
3. Operate the blower dry for a few minutes at no load to check for correct rotation and smooth operation.
4. Turn the water on and adjust flow as recommended for the individual blower. Make sure the water discharges freely from the outlet piping.
5. Apply vacuum and observe operation at the desired inlet condition.
Shutdown
It is possible to shut down the blower for brief periods by relieving the inlet vacuum, shutting off the water, and then stopping the blower.
To avoid rusting during a slightly longer shutdown period, operate the blower under a partial vacuum without the water injection, allowing the blower to heat within safe limits. The heat will tend to drive off residual moisture.
For extended shutdown, oil may be injected into the inlet of the heated blower just prior to shutting down the blower. The oil will provide a protective coating on the internal components. Make sure the water is completely shut off after shutdown.
Operator’s Manual 2009 Rev B p/n 2009
06
Operation
Special coatings or platings are available to minimize rusting or corrosion in applications where blowers can remain wet.
Always use vertical-flow blowers with two-lobed, plugged rotors. Always orient the system with the blower intake at the top and discharge at the bottom.
!
CAUTION
Water injection can cause lime build-up on rotors. Check water supply for hardness. The use of water softeners, other chemicals, or distilled water may be necessary to prevent or remove this build-up. However, due to the wide variations in mineral content, pH, and chemical content of water that can be injected, Tuthill Vacuum & Blower Systems cannot be responsible for damage which may result should this build-up occur. Units should be inspected regularly to determine any problems.
For liquid injection other than water, consult the factory.
RECOMMENDED SHUTDOWN
PROCEDURE TO MINIMIZE RISK OF
FREEZING OR CORROSION
When an air piping system has high humidity or moisture, water condensation can occur after the blower is shut down and it begins to cool.
Condensation creates an environment favorable to corrosion of the iron internal surfaces and to ice formation in cold weather. Both conditions can close the operating clearances, causing the blower to fail upon future start-up.
The following shutdown procedure minimizes the risk of moisture condensation, corrosion, and freezing.
27
06
Operation
Care must be taken so as not to overload or overheat the blower during this procedure.
1. Isolate the blower from the moist system piping, allowing the blower to intake atmospheric air. Operate the blower under a slight load, allowing the blower to heat within safe limits. The heat generated by the blower will quickly evaporate residual moisture.
2. For carpet cleaning applications, after the work is completed, simply allow the blower to run
3 – 5 minutes with the suction hose and wand attached. The suction hose and wand will provide enough load to the blower to evaporate the moisture quickly.
3. For extended shutdown, inject a small amount of a light lubricating oil such as 3-in-One ® or a spray lubricant such as WD-40 ® into the inlet of the blower just before shutdown (3-in-One and WD-40 are registered trademarks of
WD-40 Company) . The lubricant will provide an excellent protective coating on the internal surfaces. If using a spray lubricant, take care to prevent the applicator tube from getting sucked into the blower. The applicator tube will damage the blower, likely to a degree where repair would be required.
4. If the blower is being taken out of commission for an extended period of time, see Long-
Term Storage on page 31 .
28 Operator’s Manual 2009 Rev B p/n 2009
07
MAINTENANCE
GENERAL
Regular inspection of the blower and its installation, along with complete checks on operating conditions, will pay dividends in added life and usefulness. Also, service the drive per the manufacturer’s instructions and lubricate the coupling or check the belt drive tension. Use thermometers and gauges to make sure blower operating temperature and pressure remain within allowed limits.
!
DANGER
The blower and parts may contain hazardous media.
Assure that pump and parts are evacuated of hazardous media prior to servicing.
!
CAUTION
The electrical service must be isolated and de-energized prior to maintenance. Apply appropriate procedures to assure electrical supply is de-energized and cannot be inadvertently energized during maintenance.
Assure piping and product is isolated prior to maintenance of blower. Apply appropriate procedures to assure piping and product is isolated and that inadvertent opening of valves cannot occur during maintenance.
Operator’s Manual 2009 Rev B p/n 2009
!
CAUTION
During routine maintenance, inspect and assure that guards are in place and secure.
Pay special attention to lubrication of timing gears and bearings according to the information in
Lubrication on page 14 .
When a blower is taken out of service, it may require internal protection against rusting or corrosion. The need for such protection must be a matter of judgment based on existing conditions as well as length of downtime. Under atmospheric conditions producing rapid corrosion, protect the blower immediately. See Long-Term Storage on page 31 .
REGULAR MAINTENANCE
A well-designed maintenance program will add years of service to the blower.
Check a newly installed blower frequently during the first month of operation, especially lubrication.
With the blower at rest, check the oil level in both the gear (drive) end and free (non-drive) end of the blower and add oil as needed. Complete oil changes are recommended every 1,000 – 1,200 operating hours, or more frequently depending on the type of oil and operating temperature. Also, change the oil more frequently if pumping corrosive vapors or where excessive operating temperatures are encountered. The following is recommended as a minimum maintenance program.
29
07
Maintenance
DAILY
1. Check and maintain oil level, and add oil as necessary.
2. Check for unusual noise or vibration ( See
Troubleshooting on page 38 ).
WEEKLY MONTHLY
1. Clean all air filters. A clogged air filter can seriously affect the efficiency of the blower and cause overheating and oil usage.
1. Inspect the entire system for leaks.
2. Inspect the condition of the oil and change if necessary.
2. Check the relief valve to make sure it is operating properly.
3. Check drive belt tension and tighten if necessary.
Oil levels should be checked every 24 hours of operation.
Proper oil drain schedules require that oil be changed before the contaminant load becomes so great that the lubricating function of the oil is impaired or heavy disposition of suspended contaminants occurs. To check the condition of the oil, drain a sampling into a clean container and check for the presence of water or solids. Slight discoloration of the oil should not necessitate an oil change.
In developing a stock of spare parts, consider the following factors:
• The degree of importance in maintaining the blower in a “ready” condition
• The time lag in parts procurement
• Cost
• Shelf life (seals and O-rings)
SPARE PARTS
Should adjustments or replacement eventually be needed, repairs can often be performed locally as described in this manual after obtaining required parts. Personnel should have a good mechanical background and be thoroughly familiar with the procedures outlined in this manual.

FACTORY SERVICE AND REPAIR
With proper care, Tuthill Vacuum & Blower
Systems blowers will give years of reliable service.
The parts are machined to close tolerances and require special tools by mechanics who are skilled at this work. Blowers that are still under warranty must be returned to the factory, freight prepaid, for service. Contact a customer service representative for information on how to return the blower for warranty evaluation.
Current regulations require Material Safety
Data Sheet to be completed and forwarded to
Tuthill Corporation on any unit being returned for any reason which has been handling or involved with hazardous gases or materials.
This is for the protection of the employees of
Tuthill Corporation who are required to perform service on this equipment. Failure to do so will result in service delays.
30 Operator’s Manual 2009 Rev B p/n 2009
When returning a blower to the factory for repair, under warranty, please note the factory will not accept any unit that arrives without authorization. Contact the Service Department for return authorization.
LONG-TERM STORAGE
Any time the blower will be stored for an extended period of time, make sure it is protected from corrosion by following this procedure:
1. Spray the interior (lobes, housing, and end plates) with rust preventative. Repeat as conditions dictate and at least on a yearly basis.
2. Fill both end covers completely full of oil.
3. Firmly attach a prominent tag stating that the end covers are full of oil and must be drained and refilled to proper levels before start-up.
4. Apply a rust-preventative grease to the drive shaft.
5. Spray all exposed surfaces, including the inlet and discharge flanges, with rust preventative.
6. Seal inlet, discharge, and vent openings. It is not recommended that the blower be set in place, piped to the system, and allowed to remain idle for a prolonged amount of time. If any component is left open to the atmosphere, the rust preventative will escape and lose its effectiveness.
7. During storage, ensure that the blower does not experience excessive vibration.
8. Attach a desiccant bag to one of the covers to prevent condensation from occurring inside the blower. Make sure any desiccant bag (or bags) is so attached to the covers that they will be removed before start-up of the blower.
9. Store the blower in an air conditioned and heated building if possible. If air conditioned and heated storage is not possible, make conditions as dry as possible.
Operator’s Manual 2009 Rev B p/n 2009

DISASSEMBLY AND REASSEMBLY
DISASSEMBLY OF BLOWER
1. Drain lubricant from either end and disconnect all external oil lines. Do not attempt to remove oil distribution line bushing in the non-drive end plate until the end cover has been removed and the internal fittings are disconnected. The oil filter and heat exchanger may be removed or left fastened to the cover. Mark piping and other parts so they can be placed in their original position when reassembling.
Free End Disassembly
2. Support free end cover using a lifting strap.
Remove cap screws and install two of them as jacking screws in the tapped holes next to the dowel pins. Use two studs 8 in. (203 mm) long to assist in supporting the cover until it has cleared the dowel pins. It is not necessary to remove oil pump and the adapter plate from the cover unless these items are being replaced.
3. Remove large O-ring, four slinger cap screws
(5/16-12 point socket required), and oil slinger.
Tap the drive shaft lightly with a mallet to remove it from the rotor shaft. Remove cap screws and the oil retaining rings.
Gear End Disassembly
4. Remove drive shaft key. Remove all burrs and other defacements from the drive shaft.
All series except Seal/Lube Series 9 or
Series 66/69: Remove cap screws and place two screws in jackscrew holes provided to remove seal adapter plate. Tap out the seal
32 and discard O-ring.
Seal/Lube Series 9 or Series 66/69: Remove cap screws. Remove seal housing and remove stator portion of the mechanical seal. Using a spanner wrench, remove the adapter sleeve by turning counterclockwise. Remove mating ring and O-rings.
5. Support drive end cover as done on the nondrive end. Remove cap screws. The drive end cover also has jacking screw holes, but it must slide off the spherical roller bearing on the drive shaft. To keep the bearing outer race from cocking, use the drive shaft bearing pressing tool. See Figure 13-2 on page 44 .
6. Remove cap screws and the drive shaft.
Pull the bearing at this time unless it is to be pressed apart after the drive shaft has been removed.
7. Stand the blower up on the non-drive end on
6 in. × 6 in. (152 × 152 mm) blocks. Remove cap screws from the driven gear and align the match marks on the timing gear teeth. Using a suitable puller or extended pry bar, remove the gear shell from their hubs. The shell and hub are matched. Do not interchange. Re-mark if the original markings are no longer visible.
8. Unlock spanner nut lock washers and remove spanner nut and lockwashers. Remove gear hubs with the puller. Remove gear keys.
9. Remove oil sight gauge. Remove cap screws and mounting feet (Series 66 and 69). All feet are mounted on 1-1/8 in. (28.7 mm) hollow locating dowels from which they should easily

Disassembly and Reassembly disengage by tapping lightly with a mallet.
Discard O-rings.
10. Remove cap screws, bearing retainer rings, and end plate cap screws.
End Plate and Rotor Disassembly
11. The end plate, with the bearings, must be pulled from the rotor shafts. Make up two bearing pressing fixture plates as shown in Special Tool Drawings on page 44 along with eight pieces of 1/2"-13 all-thread flat washers and hex nuts. The use of a hydraulic ram is also recommended, but some modifications may be necessary depending on the type of equipment available. Install each plate to the bearing retainer ring mounting holes and apply pressure equally to the ends of the rotor shaft by tightening the nuts on the threaded rods. Install spacers under the plate after rotor shafts become flush with the top of the bearing. Use a hoist to pick up the end plate once the bearings have cleared the shaft.
12. After the end plate is removed, tap out the bearings. Remove the large O-ring.
Seal/Lube Series 5 or Series 19/86: Tap out lip seals.
Seal/Lube Series 8, 9, or Series 55/82/66/69:
Pull out by hand the stator portion on the mechanical seal. Retain the seal adapter for reassembly.
If the rotor shaft sleeves were removed with the end plate, pull them out by hand on the
19/86 series. On the other series you must drive them out with the bearings. To avoid damage to the sleeves do not use any hard faced hammers or steel punches to drive the sleeves out. Separate the mating rings from the sleeves.
13. To replace the PTFE washers of the labyrinth seals, remove the retaining ring, two wave springs, steel spacers, and PTFE washers.
Older units will contain six PTFE and seven steel washers in each bore. The current PTFE washers are thicker, therefore you will only use five PTFE and six steel washers when reassembling.
14. Reinstall the end plate without the bearings and seals, and secure with six cap screws equally spaced. Turn the blower over and support with blocks under the gear end plate.
15. Repeat steps 8, 11, 12 and 13 to remove nondrive end plate.
Do not damage bearing spacer when removing bearings. This spacer is only used on the free end.
16. Lift the rotors out of the housing. Unbolt the gear end plate and lift the housing off. Clean all parts and inspect for wear. It is not necessary to remove the oil distribution fittings on the end plates and the gear cover, but check them with compressed air to be sure the five orifices are not clogged.
ASSEMBLY
The assembly procedure is generally the same for all series, but notations are made where there are differences. All joints between housing, end plate, and covers are O-ring sealed. An RTV silicone sealer or the equivalent is used on the lip seals and mounting feet.
Dowel pins are used to locate end plate, housing, and covers in the proper location relative to each other. It is recommended that the gear end rotor shaft bearings, along with all other replacement parts, be purchased from Tuthill Vacuum & Blower
Systems to ensure the rotor location is correct with the proper end clearance relative to the gear end plate.

Disassembly and Reassembly
Preparation of End Plates
1. Make sure all parts are clean and free of nicks or burrs caused by disassembly. See Figure
8-2 on page 36 for dimension of seal pressing tools.
2. Position end plate with bearing bores up
(flange side down) and install components of the labyrinth seals. Starting with a PTFE washer, alternately stack five PTFE and five steel spacers in each bore. Add two wave springs, one more steel spacer and a retaining ring. Compress to seat seal.
Gear End Assembly
4. Place the non-drive end plate on 6 in. × 6 in.
(152 mm × 152 mm) blocks with the solid side up. The end plate must be blocked up so rotor shafts will not touch the floor when they are installed. Grease and install O-ring in end plate groove. Install housing, making sure dowel pins are in place. Do not bolt in place at this time.
5. Lay two pieces of steel approximately 2 in. ×
2 in. × 1/8 in. (51 mm × 51 mm × 3 mm) thick at the bottom of the housing as shown in Figure 8-1 with the end (long shafts) up.
The rotor lobes will be above the end of the housing, which is necessary when assembling this end.
Two wave springs are necessary for the proper pressure on the seal, but because of the pressure a tool as shown on page 44 is needed to press the retainer ring into its groove. The tool will center the labyrinth seal as it presses the retainer ring in place.
3. Seal/Lube Series 5 or Series 19/86: Apply sealer to the outside diameter (O.D.) of the lip seal. Install with lip facing upward. Tap in place with installation tool. See Figure 13-2 on page
44 . Apply grease to lip of seal.
Seal/Lube Series 8,9, or Series 55/82/66/69:
Install seal adapter. The adapter is used to anchor the stator portion of the mechanical seal. To install the seal, grease both the
O-ring and seal bore, and then push the seal, by hand, into the bore and against the seal adapter. Make sure the two dimples on the bottom of the seal case are aligned with the holes in the seal adapter. Clean the surface with soft tissue and acetone.
Never drive mechanical seal or seal tool with any type of hammer. This could result in damage to the carbon or its ability to properly seal.
DRIVE
DRIVEN
Figure 8-1 – Rotors in Housing
6. Grease and install O-ring in groove of gear end plate. Use sufficient grease to hold it in place when the end plate is turned over.
7. Install the end plate on the rotors and housing.
The end plate will rest on the ends of the rotor lobes, and there will be a space between the housing and the plate. Install all cap screws and tighten end plate to housing until tight.
8. Use six cap screws equally spaced and secure non-drive end plate against shims at bottom end of rotors. Do not torque these bolts.
9. Grease O-ring and start onto rotor shaft.
34 Operator’s Manual 2009 Rev B p/n 2009
Seal/Lube Series 5 or Series 19/86: Start sleeve over shaft (larger diameter down) while forcing O-ring into step at the bottom of the sleeve. Slide sleeve down the shaft until seated. You may encounter interference as the sleeve passes through the PTFE rings. Tap sleeve with mallet to seat if necessary.
Seal/Lube Series 8, 9, or Series 55/82/66/69:
Grease internal O-ring of mating ring portion of seal. Assemble mating ring over sleeve with lapped surface down. Slot in mating ring must line up with pin in sleeve and be flush with top of sleeve when properly installed.
Clean lapped surface of mating ring with soft tissue and acetone. Lubricate surface and start sleeve over rotor shaft while forcing O-ring into step at bottom of sleeve. Carefully slide this assembly down the shaft until seated.
10. Coat the rotor shaft with an anti-seize lubricant and press the bearing on the shaft. The bearing manufacturer numbers and/or an acid dot (inner race) should be up or toward the gears. Use the same plates that were used for disassembly and a sleeve to press on the inner race of the bearing when installing.
11. Loosen cap screws holding non-drive end plate to housing. Install bearing retainer rings and secure with cap screws. Check clearances between the rotor lobes and gear end plate.
See Assembly Clearances on page 40 for correct gear end clearances. If clearances are not within specification, re-check parts to find cause of improper clearances before proceeding. Retighten the cap screws on the non-drive end, but do not torque at this time.
12. Install keys into rotor shafts, ensuring a tight fit. Coat shafts and key with anti-seize. If new gears are being installed, disassemble gear shell from hub.
13. Heat the gear hubs to 350°F (177°C). At this temperature, the hubs should fit easily to the rotor shafts.
08
Disassembly and Reassembly
Secure with lock washers and lock nut immediately after hub is installed. Torque to proper specification. Do not install gear shell until hub has been allowed to cool.
Free End Assembly
14. Turn assembly over and support on blocks.
Remove the six cap screws and put jack screws in the holes provided in the flange of the end plate and remove the plate. Take out two shims and check free end clearance between the end of the lobes and housing using a flat bar and feeler gauges or a depth micrometer. See Assembly Clearances on page 40 .
Seal/Lube Series 5 or Series 19/86: Repeat step 9 to install sleeves.
15. Seal/Lube Series 8, 9, or Series 55/82/66/69:
Re-check carbon of seal to be sure it is clean.
All series: Reinstall end plate, making sure
O-ring is still in its groove and secure with all the cap screws.
16. Seal/Lube Series 8, 9, or Series 55/82/66/69:
Repeat step 9 to install sleeve and mating ring assemblies.
17. Install bearing spacers, and then repeat step 10 to install bearings. Secure with lock washers and lock nuts. Bend one lock washer tap into spanner nut slot to lock all nuts.
18. Install oil retainer rings and cap screws (only six required).
19. To install mounting feet, make sure the hollow dowel is in the feet. If any of the dowels are in the end plate, remove and transfer to the feet.
Grease and install the O-ring over the dowel.
Run a bead of silicone sealer 1/4 in. wide around the dowel holes on the foot mounting pad of the end plate. The sealer acts as a backup O-ring to prevent any oil leakage.
Secure with cap screw. Reconnect oil pipes and stand unit on its feet.
After heating, handle gear hubs with insulated gloves only.

The six cap screws that were in the drive gear are too long without the drive shaft.
Temporarily use the six cap screws from the driven gear. Use three in each gear (every other hole).
Adjusting Interlobe Clearance
21. The timing gears are made up of two pieces.
The outer gear shells are fastened to the inner hubs with six cap screws and are located with two dowel pins. By adding shims between a gear shell and the inner hub, the gear is moved axially relative to the inner hub which is mounted on the rotor shaft. Being a helical gear, it rotates as it is moved out and the rotor turns, changing the clearances between rotor lobes. Adding 0.012 in. (0.30 mm) shim thickness will change the rotor lobe clearance by 0.003 in. (0.076 mm).
The timing shim is formed from a number of
0.003 in. (0.076 mm) shims, which have been laminated together. Easily peel them apart as necessary.
Use feeler gauges to check the clearance at
AA (right-hand reading) and BB (left-hand reading) ( see Figure 8-2 ). The clearances should be adjusted so they are as equal between all lobes as possible, usually between
0.003 to 0.004 in. (0.076 to 0.10 mm). For best results, use feeler gauges no larger than
0.006 in. (0.15 mm).
Figure 8-2 – Checking Rotor Interlobe Clearance
Example: If AA reading is 0.030 in. (0.76 mm) and BB reading is 0.022 in. (0.56 mm), removing 0.016 in. (0.40 mm) shim will change the readings one-quarter of this amount or
0.004 in. (0.10 mm). AA reading will drop to 0.026 in. (0.66 mm) and BB reading will increase to 0.026 in. (0.66 mm).
To determine the amount of shim to add or remove from the driven gear, simply subtract the two readings 0.030 in. (0.76 mm - 0.022 in.
(0.55 mm) = 0.008 in. (0.21 mm) and double the result 0.008 in. (0.21 mm) × 2 = 0.016 in.
(0.42 mm).
To determine whether to add or remove this amount, the following rule will always apply: If the right-hand reading (AA) is greater than the left-hand reading (BB), remove this amount.
If the right-hand reading (AA) is greater than the left-hand reading (BB), remove this amount. If the right-hand reading (AA) is less than the left-hand reading (BB), then add this amount.
36 Operator’s Manual 2009 Rev B p/n 2009
If the results require you to remove shim from the driven gear and there are no shims left under this gear, go to the drive gear and add this amount for the same result. When removing or replacing a gear for shimming the timing mark should be matched and on center.
Either gear may be pulled in this position.
Completing Gear End Assembly
22. Press drive shaft bearing on drive shaft.
Remove the three cap screws from drive gear and install in the drive gear. Clean and remove all burrs from mating surfaces of the gear and drive shaft flange. Install with cap screws.
Torque gear cap screws at this time. Check drive shaft run-out at the seal journal. Do not exceed 0.003 in. (0.13 mm) T.I.R.
Series 19/86/55/82: Secure bearing with lock washer and lock nut. Bend over tab to lock in place.
23. Grease and install O-ring. To aid in the installation of the gear cover, a tool as shown in Special Tool Drawings on page 44 should be made to hold the outer race of the bearing square with the shaft. Slide the cover over the tool and secure with cap screws.
24. Seal/Lube Series 5, 8, or Series 19/86/55/82:
Press lip seal into adapter plate with lip facing inward. Grease lip, install O-ring, and carefully install assembly over drive shaft.
Seal/Lube Series 9 or Series 66/69: Grease and install O-ring on adapter flange and O-ring in the bore of adapter. Clean mating ring with soft tissue and acetone and install on adapter while aligning pin with slot in mating ring. The larger surface area of the mating ring faces inward. Install retaining ring using spanner wrench. Tighten set screws.
Lubricate seal O-ring and hand-press seal into the seal housing, making sure to align the two dimples on the bottom of the seal with corresponding holes in the seal housing. Clean carbon surface with soft tissue and acetone.
