308986 5

System Information

This manual describes pumps designed to be part of a

Hydra-Cat dispensing system that will proportion, mix, and dispense two-component fluids. The fixed ratio proportioners accurately pump and proportion two– component materials by powering two or three positive displacement pump lowers from a common air motor.

This assures that the stroke rate and stroke length of all pump lowers are identical, providing constant proportioning. The mix ratio is fixed by selecting compatible sets of two or three lowers (see Configurator

Product Order Form 309002 ).

The basic proportioner includes an air motor, lower displacement pumps, air controls, fluid inlet hardware, fluid outlet hoses, manifold blocks and relief valve.

Additional proportioner accessories are selectable to complete the proportioner pump (see Configurator

Product Order Form 309002 ).

Bare Pumps

Installation

Bare pumps, with relief valves and inlet kits but without stands, are available for those installations which require a highly customized system. For a safe and efficient system, Graco recommends that the air and fluid components supplied with the Wall Mount and

Stand models also be used in customized systems. In addition, the accessories shown in the Typical Installation drawings and discussed in the following pages of this manual should be used.

Be sure all accessories are sized properly for the air and fluid requirements of your system.

NOTES:

1. Models with three displacement pumps always use the two outer displacement pumps to supply the resin and the middle displacement pump to supply the hardener.

2. Label all pumps, hoses, fluid regulators, etc. to indicate whether they are for the resin side or hardener side of the system.

Mounting the Pump

Mount the pump to suit your installation. The bare pump can be mounted on a wall bracket or on a stand.

See the Mounting Hole Layout on page 19.

Read all instructions in the Installation section for further details.

For a wall mount, be sure the bracket and wall are strong enough to support the pump, accessories, plumbing and stress caused by pump operation.

Locate the bracket about 5 ft (1.5 m) above the floor.

Grounding

Installation

WARNING

FIRE AND EXPLOSION HAZARD

Improper grounding could cause static sparking, which could cause a fire or explosion. To reduce the risk of property damage or serious injury, follow the grounding instructions below.

Available Accessories (must be purchased separately)

2.

Air hoses: use only grounded hoses with a maximum of 500 feet (150 m) combined hose length to ensure grounding continuity.

3.

Filters: be sure your hydraulic power supply (U) is equipped with a suction filter to the hydraulic pump and a system return line filter (S) of 10 micron size.

The following grounding instructions are minimum requirements for a system. Your system may include other equipment or objects which must be grounded.

Check your local electrical code for detailed grounding instructions for your area and type of equipment. Your system must be connected to a true earth ground.

Carefully follow the manufacturer’s recommendations on reservoir and filter cleaning, and periodic changes of hydraulic fluid. Use only Graco approved hydraulic oil. Order Part No. 169–236, 5 gallon (19 liter) or

207–428, 1 gallon (3.8 liter).

1.

Pump: a. Loosen the grounding lug locknut (Fig. 4,

Item BB) and washer (AA).

b. Insert one end of a 14 ga. (1.5 mm @ ) minimum ground wire (G) into the slot in lug (CC) and tighten the locknut securely.

c. Connect the other end of the ground wire to a true earth ground.

G

4.

Hydraulic Line Accessories: on the hydraulic supply line (Item C, Fig. 3), install the following accessories in the order shown in Fig. 3, using adapters as necessary.

CAUTION

It is very important to keep the hydraulic supply system clean at all times. Be sure that all hydraulic fluid lines are absolutely clean. Blow out the lines with air and flush thoroughly with solvent before connecting to the hydraulic motor, to avoid introducing harmful contaminants into the motor.

For optimum pump performance, keep the temperature of the hydraulic oil below 130 _ F (54 _ C).

WARNING

A fluid drain valve (L) is required in both fluid lines to the gun, to help reduce the risk of serious injury, including splashing of fluid in the eyes or on the skin.

10.

All solvent pails used when flushing , according to local code. Use only metal pails, which are conductive, placed on a grounded surface. Do not place the pail on a nonconductive surface, such as paper or cardboard, which interrupts the grounding continuity.

The fluid drain valve assists in relieving fluid pressure in the displacement pump, hose, and spray gun. Triggering the gun to relieve pressure may not be sufficient.

11.

To maintain grounding continuity when flushing or relieving pressure , always hold a metal part of the dispensing unit firmly to the side of a grounded metal pail, then trigger the dispensing unit.

h.

Fluid drain valves (L): are required in your system to relieve fluid pressure in the hose and gun (see the WARNING above).

5.

Fluid hoses: use only grounded fluid hoses.

12 308986

Air Control Accessories

Installation

Install the accessories in the order shown in Fig. 5.

Mount only the air regulator (E) and a master air valve (A) at the pump. Mount all other accessories on separate wall brackets to reduce stress on the pump inlet. Note that one air filter (B) can serve multiple pumps by using an air manifold downstream from the air filter.

3. Install a pump runaway valve (D) for each feed pump to automatically shut off the air to the pump if the pump accelerates beyond the pre-adjusted setting. A pump which runs too fast can be seriously damaged.

4. Install an air line lubricator (C) for automatic air motor lubrication.

5. Install an air filter (B) to remove harmful dirt and moisture from the compressed air supply.

Automatic Pressure Relief Valves

WARNING

INJECTION HAZARD

Bleed-type master air valves (A) are required in the system in the positions shown in the Typical Installation drawings. These valves are used during system pressure relief to relieve air trapped in the air line. Trapped air can cause the pump to cycle unexpectedly and result in serious injury from moving parts, fluid injection, or fluid splashing.

WARNING

COMPONENT RUPTURE HAZARD

To reduce the risk of component rupture, which could cause serious injury and property damage, the appropriate automatic pressure relief valve (A) is required for each fluid on a plural component pump.

B A

These valves automatically relieve fluid pressure if the pump output pressure exceeds the valve’s preset pressure. Over-pressurization may occur if there is a fluid line clog upstream from the valve or if any other condition exists that causes one of the pumps to cavitate and direct all fluid pressure to the other pump(s).

See Configurator Product Order Form 309002 to determine the preset pressure in your system.

Additional System Components

Install and connect the feed pumps, solvent pump, heaters, etc. Refer to the Typical Installations

(pages 7, 8 and 9) for parts information.

Use a dry air kit or a nitrogen regulator kit to protect the fluid in the supply containers from moisture that can crystallize the fluid and cause the ball checks to malfunction. See Accessories in Configurator Product

Order Form 309002 .

WARNING

INJECTION HAZARD

Fluid emitted from the automatic pressure drain valves may be at pressures over 3000 psi (21

MPa, 207 bar). To reduce the risk of serious injury from fluid injection or fluid splashing, make sure the drain bottles are securely fastened to the frame or wall so that they can handle a sudden spurt of pressurized fluid.

How to Flush the Pneumatic System

Flushing

7. Open the hardener side drain valve (P1). Open the mixer manifold handle (KK). See Fig. 15.

WARNING

HOT SURFACE HAZARD

If your system is equipped with heaters, always shut off the main power to the heaters just prior to completing spraying.

Shut off heater 10 minutes prior to shutdown to cool the fluid and the heater. This reduces the risk of serious injury from burns. Flush system immediately after shutdown.

For flushing oil from a new system. . .

NOTE: For flushing the first time, we recommend using mineral spirits to flush out the oil. Next, flush again using a solvent that is compatible with the fluid you will be dispensing. However, be sure the mineral spirits is compatible with the material you will be pumping. If it is not compatible, check with your fluid supplier to determine an appropriate solvent for flushing out the light oil.

8. Slowly increase the air regulator (E1) setting until the pump is running slowly.

9. When the hardener lines are flushed, close the mixer manifold handle and close the drain valve (P1 ) . Close the air valve (A1). See Fig. 16.

10. Repeat Steps 6 to 9 for the resin feed pump. The resin sides uses these parts: regulator (E2), air valve (A2), drain valve (P2).

To flush the solvent valves . . .

11. Open the hardener solvent flush valve (N1) on the mixer manifold (N). See Fig. 15.

a. Be sure the solvent pump air regulator (E4) is at minimum pressure. See Fig. 16.

b. Open the solvent pump main master air valve (A6) and then open the pump air valve (A4). See Fig. 16.

NOTE: The proportioning pump does not need to to be running to clean oil from the system. Feed pump pressure is adequate to flush the system with solvent.

1. Place each feed pump intake into a separate 5 gallon grounded pail, containing about 3 gallons

(12 liters) of solvent.

c. Release the dispensing valve safety latch.

Hold the dispensing valve firmly against a grounded pail and trigger it while slowly opening the solvent pump air regulator (E4).

Operate the pump slowly until the dispense line is flushed. Release the dispensing valve trigger and engage its safety latch. Close the hardener solvent flush valve (N1).

If you are not going to use the system . . .

14. Close all air regulators, master air valves and fluid shutoff valves. Follow the Pressure Relief Proce-

dure on page 23.

WARNING

INJECTION HAZARD

To reduce the risk of serious injury from fluid injection or fluid splashing, always close the air valve (A4) to the solvent pump before opening the fluid drain valves (P2) to relieve system pressure.

This will reduce the risk of excessive pressure buildup in the opposite component hose and fittings.

How to Flush the Hydraulic System

WARNING

FIRE AND EXPLOSION HAZARD

Before flushing, read the section FIRE,

EXPLOSION, AND ELECTRIC SHOCK

HAZARD on page 4. Be sure the entire system and flushing pails are properly grounded. Refer to Grounding on page page 11.

Flush the pump:

D Before the first use

D When changing fluids

D Before storing the pump.

Flush with a fluid that is compatible with the fluid you are pumping and with the wetted parts in your system.

Check with your fluid manufacturer or supplier for recommended flushing fluids and flushing frequency.

CAUTION

Never leave water or water-base fluid in the pump overnight. If you are pumping water-base fluid, flush with water first, then with a rust inhibitor such as mineral spirits. Relieve the pressure, but leave the rust inhibitor in the pump to protect the parts from corrosion.

WARNING

To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the

Pressure Relief Procedure on page 24.

1. Relieve the pressure.

2. Hold a metal part of the gun firmly to the side of a grounded metal pail.

3. Start the pump. Always use the lowest possible fluid pressure when flushing.

4. Trigger the gun.

5. Flush the system until clear solvent flows from the gun.

22 308986

Operation

Pneumatic Pressure Relief Procedure

10. Ensure pump air pressure and main air valve are closed.

WARNING

INJECTION HAZARD

The system pressure must be manually relieved to prevent the system from starting or spraying accidentally. Fluid under high pressure can be injected through the skin and cause serious injury. To reduce the risk of an injury from injection, splashing fluid, or moving parts, follow the Pressure Relief Procedure if the spray tip/nozzle clogs and whenever you:

D are instructed to relieve the pressure,

D stop spraying,

D check or service any of the system equipment,

D or install or clean the spray tip.

11. If you suspect that the nozzle or hose is completely clogged, or that pressure has not been fully relieved after following the steps above: a. Remove and clean tip from spray gun.

b. Direct the gun into a grounded container and slowly trigger the gun.

c. If system is still plugged, very slowly loosen the fitting at the mix manifold 1/4 turn, allow liquid to run out until pressure is relieved.

d. Remove and clean or replace plugged component .

e. Tighten any loosened fittings.

1. Engage the dispensing valve safety latch.

2. Shut off the feed pump and proportioning pump air regulators and bleed-type master air valves.

f.

Very slowly loosen the nozzle or hose end coupling and relieve pressure gradually, then loosen completely. Now clear the nozzle or hose.

Handling Plural Component Fluid

CAUTION

If material is left in the heaters without fluid movement, the material could “cook” and ruin the coating as well as plug the heater. The heaters have a large mass and take several minutes to cool.

3. If the system has heaters, turn the power of f to the heaters 10 minutes prior to the completion of the application.

4. Flush the system immediately after completion of the application.

WARNING

PLURAL COMPONENT FLUID

HAZARD

Be extremely cautious when handling plural component materials and solvents used with them. Some are extremely toxic. See the Toxic Fluid Hazard warnings on page 5. Read and follow the coating and solvent manufacturer’s safety precautions and warnings.

5. Disengage the dispensing valve safety latch.

6. Hold a metal part of the dispensing valve firmly to the side of a grounded metal pail, and trigger the dispensing valve to relieve pressure.

Wear the proper protective clothing, eye protection, gloves, and clean air breathing apparatus as prescribed by the fluid manufacturers recommendations, O.S.H.A. regulations and as approved by

N.O.I.S.H. for the chemicals being used.

7. Engage the safety latch.

8. Open the mixer manifold drain valves, having a container ready to catch the drainage. Close the valves immediately.

9. Use the solvent pump to flush the mixer manifold solvent valves and fluid line(s) to the applicator.

Observe the Pot (Workable) Life Limit

Flush the mixed fluid out of the mixer, dispensing lines and equipment before it hardens. Flush the complete system when necessary to prevent the fluids from hardening in the equipment and hoses. Check the fluid manufacturer’s instructions for fluid shelf life, and flush the entire system before this time is reached. Flush the system with a compatible solvent as explained on page 21.

308986 23

Hydraulic Pressure Relief Procedure

Operation

Check the Hydraulic Fluid

WARNING

INJECTION HAZARD

To reduce the risk of serious injury, including fluid injection, splashing in the eyes or on the skin, or moving parts, always follow the Pressure Relief Procedure whenever you:

D are instructed to relieve the pressure,

D shut off the pump,

D stop spraying,

D check or service any of the system equipment,

D or install or clean the spray tip/nozzle.

1. Lock the gun trigger safety.

2. Shut off power to the feed pumps.

3. Shut off the hydraulic power supply.

4. Close the supply line shutoff valve (P), then the return line shutoff valve (R).

5. Close the gun manifold needle valves. Unlock the gun trigger safety.

6. Hold a metal part of the gun firmly to the side of a grounded metal pail, and trigger the gun to relieve pressure.

7. Lock the gun trigger safety.

8. Open the drain valves (L, required in your system), having a container ready to catch the drainage.

9. Leave the drain valves open until you are ready to dispense again.

If you suspect that the spray tip/nozzle or hose is completely clogged, or that pressure has not been fully relieved after following the steps above, very slowly loosen the hose end coupling and relieve pressure gradually, then loosen completely. Now clear the tip/nozzle or hose.

Before starting the hydraulic power supply, check the hydraulic fluid level. Add fluid as necessary to fill lines to replace the amount used. Use only Graco approved hydraulic oil. Order Part No. 169–236, 5 gallon (19 liter) or 207–428, 1 gallon (3.8 liter).

Flush the Pump Before First Use

The pump is tested with lightweight oil, which is left in to protect the pump parts. If the fluid you are using may be contaminated by the oil, flush it out with a compatible solvent. See Flushing on page 22.

Fill Throat Packing Nuts

Keep each displacement pump throat packing nut (JJ) filled with Graco ISO Pump Oil to help prevent fluid from drying on the displacement rod and damaging the pump packings. See Fig. 17.

Verify compatibility of the pump oil with the fluids being used in the pumps. During operation very small amounts of this fluid are dragged past the seals and into the pump.

Operation

Monitor Material Supply Check Drainage Bottles and Hoses

WARNING

INJECTION HAZARD

To reduce the risk of serious injury and property damage, regularly check and clean the drain hose and bottle for the automatic pressure relief valve.

CAUTION

Establish a rigid system for monitoring the material supply to prevent the pumps from running dry. A sudden lack of material in one pump may cause many system problems, including air entrapment, spitting of the fluids, fluid “crossovers”, pump damage, downtime, and added system stresses.

If material is allowed to dry in and clog the drain hose, the automatic pressure relief valve may not fully release the fluid pressure if it opens or may cause the drain hose to burst.

Check the drain hose and bottle (38) at the start of each shift, and whenever there is an imbalance of material, to see if the automatic pressure drain valve has released material into the bottles. Clean the hose and bottle as needed. Regularly check the drain hose for cuts, leaks, or bulges and replace damaged components before using the system. See Fig. 18.

Never allow the feed pump or solvent pump containers to run dry. A dry container allows air to be pumped into the system and causes incorrect proportioning. A dry pump will quickly accelerate to a high speed, and may damage itself and the other displacement pump because it causes a pressure rise in the other pump. If a supply container becomes dry, stop the pump immediately, refill the container, and prime the system again.

Be sure to eliminate all the air from the system before continuing the application.

NOTE: The pump runaway valve mentioned on page 13 of the Installation section shuts off the pump if the pump speed accelerates quickly.

Operation

3. Turn on the heaters, if used, and allow them to warm up for 10 minutes.

Checking Mix Ratio

4. Open the mixer manifold (N) and trigger the dispense valve (S).

5. Open the feed pump air valves (A1,A2). Adjust the air regulators (E1,E2) just enough to start the pumps operating slowly.

WARNING

INJECTION HAZARD

To reduce the risk of serious injury, follow the Pressure Relief Procedure on page 23 whenever you are instructed to relieve the pressure.

6. Open the proportioning pump air valve (A3) and slowly open the regulator (E3) to start the proportioning pump.

NOTE: Since this is a fixed ratio system, you typically do not have to check the mix ratio.

7. Set the air pressure to the feed pumps at no more than 25% of proportional pressure at the fluid outlets. Use the gauges (J1) to monitor this pressure. Higher pressures may prevent the proportioning pump inlet ball checks from setting properly.

If the mixed fluid does not cure or harden properly, check the ratio of resin to hardener.

1. Flush the mixer manifold; see Step 11, page 21.

2. Follow the Pressure Relief Procedure, page 23.

8. Set the air pressure to the proportioning pump (H) to obtain the required fluid pressure. Refer to

Configurator Product Order Form 309002 .

3. Open the mixer manifold (N), handle (KK) up.

4. Set the operating pressure for the pumps. See

Steps 7 and 8 on page 27.

9. While triggering the dispensing valve, check the fluid outlet pressure gauges (J2) and make note of the pressures indicated. Check the gauges frequently during operation. These notes will help to analyze any problems that may occur since a change in displacement pump performance will be indicated by a change in pressure gauge readings.

5. Release the dispensing valve trigger and engage the safety latch.

6. Close the mixer manifold (N), handle (KK) down.

NOTE: A quick pressure drop does occur during pump stroke changeover, but should remain steady if the applicator is not triggered. Pressure loss in a static state indicates a packing or check valve leak and should be repaired.

7. Open the hardener side drain valve (P2) about three turns. Open the resin side drain valve (P1) about 1 turn. This prevents the pressure from building up on the hardener pump, which would cause the automatic pressure relief valve to open.

8. Place a grounded metal pail under the drain valves.

NOTE: Flush the mixer manifold frequently during the day’s operation. Follow Step 11 on page 21.

9. Open the mixer manifold.

308986 27

Operation

10. While observing the pump outlet gauges (J2), adjust the resin and hardener drain valves (P1,P2) until the gauges show your normal operating pressure.

Hydraulic Startup – Prime the Pump

1. See Fig. 3. Check the hydraulic fluid level before each use, and add fluid as necessary.

NOTE: The pressure must be within 20% of the original spraying pressure to get a usable test.

2. Close the supply line shutoff valve (P) and the return line shutoff valve (R).

3. Start the hydraulic power supply.

11. Close the mixer manifold. Put a separate sampling container under each drain valve.

12. Open the mixer manifold to draw a sufficient sample.

13. As you close the mixer manifold, check the pump outlet gauges (J2) again to make sure they are at your normal operating pressure.

14. If the fluid pressure is not within 20% of the normal operating pressure, flush the mixer manifold again and take another sample. If the sample ratio is incorrect, refer to the Troubleshooting chart on page 31. If the ratio is correct, the problem is with other system component.

4. Hold a metal part of the gun firmly to the side of a grounded metal pail and hold the trigger open.

5. Open the return line shutoff valve (R) first, then slowly open the supply line shutoff valve (P).

6. Run the pump slowly until all air is pushed out and the system is fully primed. Always use the lowest pressure necessary to get the desired results.

Higher pressures cause premature pump wear.

7. Release the gun trigger and lock the trigger safety.

With adequate hydraulic volume supplied to the motor, the pump will start and stop as you open and close the gun.

15. Close the drain valves (P1,P2).

28 308986

Operation

9. Use the fluid pressure gauge (F) and pressurereducing valve (H) to control pump outlet pressure and pump speed. Always use the lowest hydraulic flow and pressure necessary to get the desired results. Higher pressure causes premature pump wear.

CAUTION

Do not allow the pump to run dry. It will quickly accelerate to a high speed, causing damage. If your pump is running too fast, stop it immediately and check the fluid supply. If the container is empty and air has been pumped into the lines, refill the container and prime the pump and the lines, or flush and leave it filled with a compatible solvent. Eliminate all air from the fluid system.

308986 29

Shutdown and Care of the System

WARNING

INJECTION HAZARD

To reduce the risk of serious injury, follow the Pressure Relief Procedure on page 23 whenever you are instructed to relieve the pressure.

System Shutdown

To shut the system down, shut off the air to all pumps, trigger the dispensing valve into a grounded metal waste container. Close the mixer manifold valves.

Flush all the mixed fluid out of the mixer manifold, hoses and dispensing equipment. See page 21. Then follow the Pressure Relief Procedure, page 23.

Pump Inlet Strainer Cleaning

If the fluid pressure from the feed pump to the proportioning pump cannot be maintained on the proportioning pump intake gauge (J1), check and clean the strainer (V). See Fig. 19, page 26.

1. Relieve all feed pump pressures.

2. Remove “Y” strainer, clean, and replace.

3. Restart feed pumps and check for open inlet feed lines.

Clean Static Mixer

Visually inspect the static mixer (G) weekly. Replace the static mixer if clogged or damaged. See Fig. 21.

1. Follow the Pressure Relief Procedure on page 23.

2. Remove the hose (H) from the static mixer (G).

3. Unscrew the static mixer (G) from the mix manifold.

4. Push the mixer element out of the static mixer by inserting a wooden dowel at the adapter (I) end.

Clean all parts with a compatible solvent, and reassemble.

5. Install the static mixer (G). The arrow on the static mixer must point down. Apply tape and sealant to the threads of the static mixer.

Using a wrench on the flats of the center pump’s displacement rod, screw the rod out of the yoke (114). See Detail B in Fig. 25. Remove the pump from the yoke (114) then the washer (115) from the rod on the pump.

4. Refer to the appropriate instruction manual for servicing the displacement pump.

Reassembly

1.

Three Displacement Pump Models Only

Slide the center displacement pump rod through the tie plate (121), center locknut (123), and washer (115). Thread the displacement rod into the yoke (114) by turning the complete cylinder. Use a wrench on the flats of the displacement rod for final tightening. Torque to 53–67 ft-lb (72–91 N S m) .

Push the cylinder up into place in the tie plate and install the center locknut (123).

DETAIL B

3. Move the air motor to the bottom of its stroke.

Check for movement of the air motor yoke at each displacement rod. With the rods centered, tighten the locknuts (113) securely and torque to 53–67 ftlbs (72–91 N S m) .

4. Tighten the throat packing nut just enough to prevent leakage, no tighter.

2.

All pumps

Slide the outer two displacement pump rods through the tie plate (121), outer locknuts (122), and washers (115). Install the locknuts (113) loosely on the displacement rods. Push the cylinders up into place in the tie plate and install the outer locknuts (122).

5. Reconnect the swivel unions to the pumps. Hold the intake valve (C) steady with a wrench to prevent it from turning.

Disconnecting the Displacement Pumps

NOTE: For displacement pump repair instructions, refer to the separate displacement pump manual

307–430, supplied.

WARNING

To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the

Pressure Relief Procedure on page 23.

Reconnecting the Displacement Pumps

1. Apply thread sealant to the threads of the coupler

(2) and screw it onto the hydraulic motor. Place the gasket (3) on the yoke (4). Apply sealant to the threads of the yoke and screw it into the coupler.

See Fig. 26.

2. Apply thread sealant to the top threads of the tie rods (5). (The top is the end with short threads, and without flats.) Screw the rods into the base of the hydraulic motor (1).

1. Flush the pump if possible. Stop the pump at the bottom of its stroke. Relieve the pressure.

2. Relieve pressure in the accumulator, if used.

Disconnect the hydraulic supply, return, and drain lines from the motor. Disconnect all hoses from the pump.

3. Plug all hydraulic connections to avoid contamination.

4. Take note of the orientation of the pump fluid outlets to the hydraulic fluid inlet of the motor.

5. Unscrew the tie rod locknuts (23) and the extension rod locknuts (14). Slide the displacement pumps down off the tie rods (5). See Fig. 26.

6. Remove the screws (12) and lockwashers (13) from the tie plate (6). Pull the tie plate off the displacement pumps (7).

7. Remove the cotter pins (11). Unscrew the rod extensions (10) from the displacement rods (R).

Inspect the o-rings (24).

8. If you are servicing the hydraulic motor (1), remove the tie rods (5), yoke (4), gasket (3), and coupler (2).

NOTE: For hydraulic motor repair instructions, refer to the separate motor manual 307–158, supplied.

3. Lubricate the o-rings (24) and install them on the displacement rods (R). Lubricate the threads of the rods.

4. Screw the extension rods (10) onto the displacement rods (R). Align the holes in the rods and insert the cotter pins (11).

5. Attach the tie plate (6) to the displacement pumps (7), using the six screws (12) and lockwashers (13). Orient the fluid outlets of the displacement pumps as was noted in step 4 under

Disconnecting the Displacement Pumps.

6. Slide the tie plate (6) onto the tie rods (5) until the threads of the extension rods (10) protrude from the yoke (4). Screw the locknuts (14) onto the extension rods. Torque to 40–50 ft-lb (53–68 N S m).

7. Screw the tie rod locknuts (23) onto the tie rods (5). Torque to 40–50 ft-lb (53–68 N S m).

8. Remount the pump and connect all hoses.

9. Reconnect the ground wire if it was disconnected during repair.

10. Turn on the hydraulic power to the motor and run the pump slowly, to make sure it is operating properly.

11. Fill the packing nut/wet-cup 1/3 full of ISO pump lube.

Graco Standard Warranty

Graco warrants all equipment manufactured by Graco and bearing its name to be free from defects in material and workmanship on the date of sale by an authorized Graco distributor to the original purchaser for use. With the exception of any special, extended, or limited warranty published by Graco, Graco will, for a period of twelve months from the date of sale, repair or replace any part of the equipment determined by Graco to be defective. This warranty applies only when the equipment is installed, operated and maintained in accordance with Graco’s written recommendations.

This warranty does not cover, and Graco shall not be liable for general wear and tear, or any malfunction, damage or wear caused by faulty installation, misapplication, abrasion, corrosion, inadequate or improper maintenance, negligence, accident, tampering, or substitution of non–Graco component parts. Nor shall Graco be liable for malfunction, damage or wear caused by the incompatibility of

Graco equipment with structures, accessories, equipment or materials not supplied by Graco, or the improper design, manufacture, installation, operation or maintenance of structures, accessories, equipment or materials not supplied by Graco.

This warranty is conditioned upon the prepaid return of the equipment claimed to be defective to an authorized Graco distributor for verification of the claimed defect. If the claimed defect is verified, Graco will repair or replace free of charge any defective parts. The equipment will be returned to the original purchaser transportation prepaid. If inspection of the equipment does not disclose any defect in material or workmanship, repairs will be made at a reasonable charge, which charges may include the costs of parts, labor, and transportation.

THIS WARRANTY IS EXCLUSIVE, AND IS IN LIEU OF ANY OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT

NOT LIMITED TO WARRANTY OF MERCHANTABILITY OR WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE.

Graco’s sole obligation and buyer’s sole remedy for any breach of warranty shall be as set forth above. The buyer agrees that no other remedy (including, but not limited to, incidental or consequential damages for lost profits, lost sales, injury to person or property, or any other incidental or consequential loss) shall be available. Any action for breach of warranty must be brought within two (2) years of the date of sale.

Graco makes no warranty, and disclaims all implied warranties of merchantability and fitness for a particular purpose in connection with accessories, equipment, materials or components sold but not manufactured by Graco. These items sold, but not manufactured by

Graco (such as electric motors, switches, hose, etc.), are subject to the warranty, if any, of their manufacturer. Graco will provide purchaser with reasonable assistance in making any claim for breach of these warranties.

In no event will Graco be liable for indirect, incidental, special or consequential damages resulting from Graco supplying equipment hereunder, or the furnishing, performance, or use of any products or other goods sold hereto, whether due to a breach of contract, breach of warranty, the negligence of Graco, or otherwise.
