SECTION I - GENERAL DESCRIPTION
1-1. GENERAL. These BUDGIT Series 6000 Air Hoists are precision built chain type hoists which are built in three capacity sizes: 1, 2, and 3 ton. All models use coil type load chain and have pendant throttle controls. There are model variations with hook or lug type suspensions. Hoists are also provided in spark resistant models and corrosion resistant models. (Note:
Spark resistant models have capacity ratings lower than standard models).
1-2. BASIC CONSTRUCTION. All sizes and models of these
BUDGIT Series 6000 Air Hoists are of the same basic design, having many common and interchangeable parts. They consist primarily of an aluminum alloy frame and gearcase cover which houses an automatic load brake and gear train. An air motor is mounted on the rear of the frame. An upper hook or lug bracket for suspending the hoist is attached to the top of the frame. An alloy steel coil load chain with lower block assembly is employed to raise and lower loads. Upper and lower limits of hook travel are limited by chain mounted limit actuators. Hoist operation is controlled by a pendant throttle control assembly.
1-3. DIFFERENCES BETWEEN MODELS AND SIZES. The main differences between hoist models are in the reeving of the load chain and the suspension employed. These are described in Paragraphs a and b, below.
a. On standard 1 ton capacity hoists, the load chain is single reeved (one part of chain); on standard 2 ton capacities, the chain is double reeved (two parts of chain); on standard 3 ton capacities, the chain is triple reeved
(three parts of chain). Coil type chain is full-flexing, electric welded, link chain; carburized steel on standard and corrosion resistant models and stainless steel on spark resistant models. Both types are especially designed for use in hoisting and have special calibrated pitch. (Note:
On corrosion resistant models, the load chain is zinc plated).
b. Suspension differences include a conventional hook type mounting and a lug type mounting. Hook suspension allows portability permitting hoist to be easily moved from job to job. Lug suspension permits hoist to be rigidly mounted to overhead structure or attached to BUDGIT Rigid Mount
Trolleys, affording unusual headroom advantage.
1-4. MAN-GUARD OVERLOAD CLUTCH. BUDGIT Series 6000
Air Hoists have a MAN-GUARD label on the sides of the counterweighted cover and are equipped with an overload clutch that is designed to help guard against excessive overloads.
The clutch is built into the load brake gear. It is a cone-friction clutch that connects the first reduction gear (load brake gear) to the load brake output pinion shaft. A belleville disc spring provides clutch pressure between the gear and its cone shaped gear center. An excessive overload causes the load brake gear to rotate without turning the gear center and output pinion shaft. The clutch is located between the load brake and the motor, thus allowing load brake to function in its normal manner.
See Paragraph 3-5 for operation.
SECTION II - INSTALLATION
2-1. GENERAL. BUDGIT Series 6000 Air Hoists are completely lubricated and load tested before being shipped from the factory.
The hoist is shipped with pendant handle and hose assembly packed loose in the shipping carton. See Paragraph 2-2.e for attachment. To place hoist in service, attach to a suitable overhead suspension (Paragraph 2-2) in area to be used; perform pre installation check (Paragraph 2-3); and connect hoist to air service (Paragraph 2-4).
2-2. SUSPENDING HOIST.
a. On hook suspended hoists, select a suitable overhead support in area hoist is to be used (one capable of holding combined weight of hoist and its capacity load) and hang hoist up. Be certain that upper hook is firmly seated in
center of hook saddle and that the spring safety latch
is properly closed over hook opening. In some cases, it may be necessary to first remove spring latch before hook will fit over a support. Reinstall latch after hook is engaged.
b. On lug suspended hoists, select a suitable overhead support in area hoist is to be used (one capable of holding combined weight of hoist and its capacity load). Mount hoist using through bolts of appropriate size to fit mounting holes in suspension lug at top of hoist. (See table below).
Use only suspension bolts provided by Yale
Lift-Tech.
CAUTION
The structure used to suspend hoist must be of sufficient strength to withstand reasonable forces to which hoist and support may be subjected. Hoist must be aligned with load to avoid side pulls.

*S.R. = Spark Resistant Models c. On lug suspended hoists, the suspension lug may be installed for cross mounting or parallel mounting of the hoist. To rotate hoist 90° follow the instructions below:
(1) On single reeved hoists removed suspension lug per instructions in Section VII, Paragraph 7-3c.(1) and
Figure 7-17. Lift lug from hoist frame, rotate to desired position and replace on locating pins. Insert suspension bolt and nut. Turn nut on top of lug while holding nut inside of hoist frame with drift until grooved pin holes are aligned.
Page 3
WARNING
Be certain to replace grooved pin thru nut and suspension bolt. Grooved pin must be tight.
(2) On double reeved hoists, remove hex socket head screw in lower lock plate. Remove lower lock plate.
Rotate suspension lug to selected position and replace lock plate and hex socket head screw.
(3) On triple reeved hoists, the hanger bracket must first be removed from the hoist to provide access to suspension nut per Section VII, Paragraph 7-2.a.(4) and Figures 7-1 and 7-2.
To removed lug bolt, follow instructions in Section VII,
Paragraph 7-3.b.(3). With bolt removed lift lug from hanger and reposition as desired. The lug is located and prevented from turning by integral lugs on adjacent surfaces of the lug and the hanger. Reinstall lug bolt, spherical washers and nut. Align hole in nut and lug bolt.
Reassemble hanger bracket to hoist.
2-3. PRE-INSTALLATION CHECK. Check Oil Level. (Figure
4-1) The gearcase has been filled with oil, to the proper level at the factory. However, the oil level should be checked before hoist is operated.
Remove and discard felt shipping plug from oil filler on side of hoist frame. Check oil level by removing oil level plug (side of frame). Observe if oil level is even with bottom of tapped hole.
If it is not, add oil, as specified in Paragraph 4-4.c. Also check load chain. Be sure it is properly lubricated. See Paragraph 4-
3.
2-4. CONNECTING HOIST TO AIR SERVICE.
a Connect hoist to nearest filtered and lubricated air source using 3/4" I.D. air hose (see Figure 2-1). Avoid use of hose assemblies of smaller diameters that will cause air flow restrictions and reduce hoist performance.
b. If hoist is suspended by trolley, provide sufficient hose to reach from air source to farthest point of trolley travel.
BUDGIT Hose Trolleys are recommended to keep hose up out of the way.
WARNING
Be certain to replace grooved pin thru nut and lug bolt. Grooved pin must be tight.
d. On rigid mount trolley suspended hoists, the trolley side plates must be properly spaced so trolley will fit I-beam on which hoist will operate. Adjustment for various I-beam sizes is accomplished by rearrangement of spacer washers on the thru bolts which connect trolley side plates to suspension lug on hoist. Refer to instruction sheet furnished with BUDGIT Rigid Mount Trolleys for complete instructions.
WARNING
If trolley is mounted on an open-end beam, end stops must be installed to prevent trolley from running off the end of the beam resulting in Injury to operator and others and damages to load and other property.

Figure 2-1. Connecting Air Hose to Hoist
c. A filter and lubricator unit (Figure 2-2) must be installed between air source and air hose leading to hoist. These keep air flowing to hoist free of dirt and add lubricant to air so internal parts of motor are constantly lubricated.
Use a good grade of spindle oil, approximate viscosity
180 ssu at 100° F., air powered tool oil, or S.A.E. 10W machine oil. Yale
Lift-Tech distributors can provide filterlubricator units.
e. To connect pendant throttle control, refer to Figure 8-9.
The host with a straight connection at the top (Ref. No.
10) attaches to the left connection of the supply head as shown. The hose with the long elbow at the top connects to the upper right connection and the hose with the short elbow at the top connects to the lower right connection of the supply head. Assemble the parts at the upper end of the strain relief cable as shown. Make the cable tight enough to support the weight of the handle and hoses before tightening the wire rope clips.
f. If chain container is to be used on hoist, install it following instructions furnished with container.

Figure 2-2. Air Filter and Lubricator Unit
Page 4
d. The recommended operating air pressure for all capacities of BUDGIT Air Hoists is 90 psi. When line pressure exceeds 100 psi (at hoist when hoist is operating), it is recommended that a pressure regulator valve be provided in the air supply line to maintain proper pressure. Although there is a wide range of pressures within which the hoists will operate, motor efficiency may decrease more rapidly than the drop in air pressure on a percentage basis.
Refer to "Performance Charts," See Figure 2-3.
b. When hoist is to be used without a chain container, check that tail chain anchor screw is secure. When hoist is to be used with a chain container, tail chain may be left unattached
PROVIDED LIMIT ACTUATOR IS IN PLACE IN ACCORDANCE
WITH ABOVE.
c. Check to see that limit stop is in proper position.
d. Check hooks. They should not be bent or distorted and should not be opened beyond the correct opening sizes given in Figures 5-5 and 5-6. Hook latches should not be bent or damaged and springs not broken.
e. Check chain to make sure it is not twisted or kinked. Be sure lower block on double reeved models has not been capsized. Be sure load chain is lubricated. See Paragraph
4-3.

SECTION III - OPERATION
3-1. GENERAL. Operation of BUDGIT Series 6000 Air Hoists is controlled by a pendant throttle control. The Pendant Throttle
Control has a convenient lever type control valve handle (Figure
3-1) suspended from the control manifold.
3-2. PRE-OPERATION CHECKS. Check the following before operating hoist with load: a. Check limit actuator(s) on load chain. On all capacities a square shaped actuator should be firmly bolted to the 9th link from the tail chain anchor end of the load chain. On single line hoists an actuator should be firmly bolted to the first link above the lower block. On three line models the actuator is to firmly bolted three links above the lower block on the chain that dead ends in the lower block. Two line models have no limit actuator on the chain above the lower block.
WARNING
Never operate hoist with defective or missing limit actuators, defective hooks or load chain. See Paragraph 5-2 for aid in checking load chain condition.
3-3. OPERATING HOIST. With hoist installed and air pressure turned on, hoist is operated in the following manner: a. Depress throttle valve lever marked
to raise load. See Figure 3-1.
b. Depress throttle valve lever marked to lower load.
being depressed.
c. Release lever being depressed to stop either lifting or lowering.
d. Speed of lifting and lowering is varied by the position of the throttle valve lever
Figure 3-1.
Pendant Throttle
Control Handle
e. Speed of lowering can be reduced from the maximum by adjusting a screw in the upper fitting of the down valve supply hose.
3-4. UPPER AND LOWER LIMIT STOPS. Upper and lower limit actuators are provided to guard against overtravel of load in either raising or lowering direction, which can cause damage to hoist. When highest position is reached, the lower block or lower block limit actuator will cause the overload clutch to slip.
When the lowest block position is reached, the tail chain actuator will cause the overload clutch to slip. Limit stops are intended as safety devices and should not be used on a routine basis to stop block travel. Lowering full rated capacity load at full rated speed Into the limit stop is an especially severe condition and must not be knowingly done at any time.
Page 5
3-5. MAN-GUARD OVERLOAD CLUTCH OPERATION. The overload clutch is factory preset at assembly so that the hoist will lift its full rated load but will refuse to lift overloads within a range of 110 percent rated load to 180 percent rated load. If the load to be lifted exceeds the clutch factory setting, the motor will continue to run and will rotate the load brake gear without lifting the load. Whenever this occurs, immediately release the "UP" control to prevent overheating of the clutch friction surfaces and motor.
NOTICE
Always know load to be lifted. Loads greater than rated capacity are not to be lifted.
3-6. LOAD CHAIN. Make sure the load chain is lubricated according to the requirements of Paragraph 4-3 before operation. For hoists with stainless steel load chain carefully inspect for unusual chain wear daily during the first week of operation then return to the regular maintenance schedule of
Section V.
3-7. PULLING AND PIVOTING HOIST AND LOAD.
a. The Pendant Throttle Control handle is supported by a strain cable that is suitable for pulling trolley suspended hoists when empty or lightly loaded. Use a tag line or pole to pull or push loads to traverse heavily loaded hoists.
Observe caution to stay clear of loads.
b. To pivot load, push on one corner of load. Lower hook will swivel through 360° to permit load to be swung to the desired position. The upper hook (hook suspension models) is also designed to rotate so that hoist will swing to face the load.
WARNING
Equipment covered herein is not designed or suitable as a power source for lifting or lowering persons.
3-8. OPERATION PRECAUTIONS
Safe operation of an overhead hoist is the operator's responsibility. Listed below are some basic rules that can make an operator aware of dangerous practices to avoid and precautions to take for his own safety and the safety of others.
Observances of these rules in addition to frequent examinations and periodic inspection of the equipment may save injury to personnel and damage to equipment.
a. Personnel not physical fit or properly qualified, shall not operate hoist.
b. Operate hoist cautiously to become familiar with its performance.
c. Do not lift loads greater than the hoist rated load.
d. Never lift or transport a load until all personnel are clear. Never lift people on hook or load.
e. Stand clear of all loads and never travel loads over people.
f. When lifting load make certain it is free to move and will clear all obstructions.
g. Do not divert attention from load while operating hoist.
Never leave a suspended load unattended.
h. Do not operate hoist unless upper and lower limit actuators are operating properly.
j.
Do not use limit stop as normal operating stop. This is a safety device only.
k. Take up chain slack carefully to avoid jerking load, possibly overloading hoist.
I.
Never use hoist chain as a lifting sling around a load or as an electrical ground for welding.
m. Always be sure there Is no twist In coil load chain. On 2
& 3 line coil chain hoists, check to see that lower block
Is not capsized between strands of chain.
n. Avoid operating hoist when hook is not centered under hoist. Be sure that hoist trolley or other support mechanism Is correctly positioned for handling the load before lifting.
o. Do not operate hoist with twisted, kinked, badly worn or damaged chain.
p. Do not operate damaged or malfunctioning hoist.
q. Do not "Jog" unnecessarily.
r. Conduct regular visual inspections for signs of damage or wear.
s. Observe recommended inspection and maintenance procedures.
t. Never operate hoist with hooks that have opened up.
See Figure 5-5 and 5-6.
u. Do not remove or obscure warning labels.
v. The supporting structure or anchoring means shall have a load rating at least equal to that of the hoist w. Hoists shall not be used in locations that will not allow operator movement to be free of the load.
x. The operator shall Insure that he has firm footing or is otherwise secured before operating the hoist.
y. The load sling or other approved devices shall be seated properly In the saddle of the hook and the hook latch shall be closed before operating hoist.
z. Before lifting a load the operator shall be certain that load Is not caught on any obstructions.
aa.When starting to lift or pull, the load should be moved a few inches at which time the hoist should be checked for proper load holding action. The operation shall be continued only after the operator Is assured that the hoist Is operating properly.
ab.The operator should not leave a loaded hoist unattended at the end of a work shift or for extended periods during the work shift. Where operations are such that this condition cannot be avoided the operator must be assured that the condition does not create a hazard to personnel or property.
ac.Use common sense and best judgment whenever operating a hoist. Observe American National Standard
Safety standard, ANSI B30.16, latest issue.

SECTION IV - LUBRICATION
4-1. GENERAL. The lubrication services outlined in Paragraphs
4-2 thru 4-5 should be performed at regular intervals to maintain top hoist performance and insure long life. The frequency for lubrication services will depend on the type of hoisting service that hoist is subjected to and should coincide with periodic preventive maintenance inspection. See Section V -
Maintenance.
4-2. SERVICE AIR LINE LUBRICATOR. Servicing air line filter and lubricator unit is of primary importance since it's the only source of lubrication for control valves and air motor. Fill lubricator with a good grade of light spindle oil or air powered tool oil, and follow the manufacturer's recommended service procedure.
4-3. LUBRICATE LOAD CHAIN. A small amount of lubricant will greatly increase load chain life, therefore, chain should not be allowed to run without lubricant. Chain should be cleaned and lubricated as directed in Paragraph a, below. User should set up a regular schedule for chain lubrication after observing operating conditions for a few days.
a. Under ordinary conditions only weekly attention will be necessary. Under hot and dirty conditions it may be necessary to clean chain at least once a day and lubricate it several times between cleanings. Thoroughly clean chain with an oil solvent and relubricate by coating it lightly with bar and chain oil (LUBRIPLATE or equal). Make sure that lubricant coats wear surfaces between links.
b. BUDGIT Series 6000 spark resistant air hoist models use stainless steel load chain that must be well lubricated at all times and must be inspected daily when in use.
See Paragraph 5-2.a.(2).
4-4. CHANGE GEARCASE OIL (Figure 4-1).
a. Remove drain plug from bottom of hoist frame and drain oil from gearcase. Replace plug.
b. Remove oil level plug from side of hoist.
c. Refill gearcase thru oil filler to proper level (bottom of oil level plug hole) using Automatic Transmission Fluid -
DEXRON
®
Type. This is an all weather oil available from all major oil companies. 1-1/2 pints of oil are required.
4-5. LUBRICATE UPPER HOOK AND LOWER BLOCK
ASSEMBLY.
a. Apply a few drops of graphite suspension oil on shank of upper hook where it enters frame.
b. Apply a few drops of graphite suspension oil on shank of lower hook where it enters lower block. Hook rotation bearing may be removed for cleaning and relubricating if necessary. See Paragraph 7-5.
c. On lower block assemblies with 2 or 3 lines of load chain also apply a good grade of bearing grease thru pressure fitting in end of sprocket pin to lubricate bearing in chain sprocket.
d. On models with 3 lines of load chain lubricate sprocket in hanger bracket with a few drops of graphite suspension oil in hole provided in center of sprocket hub.
WARNING
Before performing any internal work on hoist, be certain power is shut off.
Figure 4-1. Location of Oil Filler and Plugs
SECTION V - MAINTENANCE
5-1. GENERAL. Preventive maintenance services required on
BUDGIT Series 6000 Air Hoists are for the most part, simple periodic inspection procedures to determine condition of hoist components. Below are suggested inspection procedures, based on daily average hoist usage.
5-2. THIRTY DAY INSPECTION. Hoist may be left suspended.
a. Inspect Load Chain.
(1) Operate hoist under load and observe operation of chain over sprocket in both directions of chain travel.
Chain should feed smoothly into and away from the sprocket. It chain binds, jumps or is noisy, first see that it is clean and properly lubricated. If trouble persists, inspect chain as outlined below.
(2) Clean chain for inspection. Examine visually for gouges, nicks, weld splatter, corrosion or distorted links. Slacken chain and check bearing surfaces between links for wear, Figure 5-1. Greatest wear will often occur at sprocket at high or low point of lift, particularly when hoist is subjected to repetitive lifting cycles. Case hardness of chain is about .015" deep.
Chain must be replaced before the case is worn thru.
Also check chain for elongation using a vernier caliper
(Figure 5-2). Select an unworn, un-stretched section
Page 7
of chain (usually at slack or tail end) and measure and record the length over the number of chain links
(pitches) indicated in Figure 5-2. Measure and record the same length of a worn section in the load side of the chain. Obtain the amount of wear by subtracting the measurement of the unworn section from the measurement of the worn section. If the result (amount of wear) is greater than the amount specified in the
"ALLOWABLE CHAIN WEAR" table, the chain has elongated beyond the maximum allowable length and must be replaced. Chain with excessively pitted, corroded, nicked, gouged, twisted or worn links should be replaced using only factory approved chain. Never
weld or attempt to repair coil chain.
Load chain for spark resistant models is made of stainless steel. Surface hardness treatment is no more than .001" deep and the core is lower in hardness than standard alloy steel load chain. For these reasons the rated capacity of spark resistant models is lower than that of standard models as follows:

CAUTION
Do not assume that load chain is safe because it measures below replacement points given herein. Other factors, such as those mentioned in visual checks above, may render chain unsafe or ready for replacement long before elongation replacement is necessary.
WARNING
When replacing coil load chain, use only factory approved chain conforming to factory specifications for material, hardness, strength and link dimensions.
Chain not conforming to BUDGIT hoist specifications may be dangerous as it will not fit in the load sprocket and chain guide correctly, causing damage to hoist, and it will wear prematurely, deform and eventually break.
(3) Removing and Replacing Coil Load Chain.
(a) Replacement coil load chain is installed by attaching it to tail end of old chain, after disconnecting old chain from side of hoist frame and removing limit actuator. New chain is then run into hoist as old chain is run out. Use open "C" links, Figures 5-3 and 5-4, for attaching chains.
Links must be identical in size to hoist chain - 5/
16" wire size with .858" pitch length for all models.
Be certain that all welds on links of replacement chain face away from center of load sprocket.
(b) Remove lower block assembly and actuator from old chain and attach them to replacement chain at end which was just run thru hoist. Install limit actuator (as noted below) on other end of chain and anchor chain to side of hoist frame.
Figure 5-1. Check Chain Wear at Bearing
Surfaces Between Links
CAUTION
Two "C" links must be used on hoists with 1 line of load chain (Figure 5-4) in order to correctly position end link on tail end of chain to fit tail end anchor at side of hoist frame; only one "C" link is required on hoist with 2 or 3 lines of load chain.

WARNING
When installing coil load chain do not attempt to hand feed chain into hoist, or use a piece of wire In place of the method described herein. To do so may result in serious internal damage to hoist, as coil chain links must be properly seated in chain sprocket before chain
Is run into hoist.
(2) On double and triple reeved hoists, check sprocket and bearing in lower block for freedom of movement and signs of damage. Lubricate if necessary. Replace damaged parts.
(3) Check hook latches. Replace damaged or bent latches of broken springs.
Page 9
WARNING
Hooks, upper or lower, damaged from chemicals, deformation or cracks or having more than 15 percent in excess of normal throat opening or more than 10 degrees twist from the plane of the unbent hook, or opened, allowing the hook latch to bypass hook tip must be replaced.
Any hook that is twisted or has excessive throat opening indicates abuse or overloading of the hoist.
Other load bearing components of the hoist should be
Inspected for damage. (See Section V, Paragraph 5-
2.d.(2) below).
C. Inspect Upper Suspension.
(1) On hook suspended models, check for bent or distorted hook. If hook is opened beyond the dimension given in Figure 5-6, it must be replaced. Also check to see that hook pivots. Lubricate if necessary. Single reeved hoists have a stop pin installed in frame adjacent to hook to restrict hook rotation. Check to see that pin is not sheared off and stop lug on hook shank is not broken.

(4) Check hook latch. Replace damaged or broken parts.
d. Inspect Motor and Frame.
(1) Check to see that bolts securing motor to frame are tight. Also check for any visible damage to motor, supply head or muffler, such as a cracked or dented housing. Replace damaged parts.
(2) Check hoist frame for signs of visible damage. If frame shows evidence of fracture, the hoist should be disassembled and inspected for further signs of damage from possible overloading. Replace damaged parts. Also check condition of limit stop.
e. Check Oil Level. Remove oil level plug (Figure 4-1). If oil level is not even with bottom of tapped hole, add Automatic
Transmission Fluid, DEXTRON® Type, to bring proper level.
5-3. SIX-MONTH INSPECTION OR 500-750 HOURS OF
OPERATION. Hoist may be left suspended.
a. Check control cable wire strain reliever to see that it is in good condition and securely attached to supply head assembly.
b. Change Gearcase Oil. See Section IV, Paragraph 4-4.
c. Relubricate Load Chain. See Section IV, Paragraph 4-3.
d. Lubricate Upper Hook and Lower Block. See Section
IV, Paragraph 4-5.
5-4. ANNUAL INSPECTION. Hoist must be disconnected from air service and removed from overhead suspension. Hoists
subjected to severe service or to adverse environments should be examined weekly or as conditions warrant.
a. Hoist should be partially disassembled as necessary to inspect hoist parts noted in Paragraphs b through e below.
Refer to Section VII for disassembly and reassembly steps as noted.
b. Inspect Pendant Throttle Control Assembly. Remove springs and valves (Paragraphs 7-6.a.(3) thru 7-6.a.(5).
Check condition of springs and valves. Replace worm or damaged parts.
c. Inspect Supply Head Assembly. Remove supply head assembly (Paragraph 7-7.a) and disassemble it as outlined. Check condition of valves. Replace worn or damaged parts.
d. Inspect Air Motor. Remove air motor assembly (Paragraph
7-2.d) and disassemble it as outline (Paragraph 7-8).
Check for worn or damaged rotor vanes. Inspect ball bearings and check condition of rotor, shaft, cylinder and end plates. Any repairs beyond replacing vanes, springs, and pins would best be done at an authorized BUDGIT repair station. Repair or replace defective parts as noted in following steps:
(1) Rotor. Examine end faces for roughness and vane slots for wear and burrs. A new vane should move in and out without binding. Smooth roughness on end faces and remove sharp edges or burrs at slot corners using a hone. Replace motor if rotor and shaft assembly is excessively worn or damaged.
Page 10
(2) Cylinder. Examine surface of bore diameter for rough circular grooves from scoring. If the cylinder is badly scored, it must be replaced. A badly scored cylinder cannot be restored by honing, since it will only enlarge bore diameter, widening seal point between rotor and cylinder, resulting in loss of speed and power. If cylinder is replaced, new shim gaskets of the proper thickness are required to maintain the original spacing of the end plates.
(3) End Plates. Check faces of front and rear end plates for wear of scoring. If wear depth is greater than .005
inch, end plates should be replaced. Light score marks can be lapped out with 150-grit abrasive cloth on a flat surface.
(4) Rotor Vanes and Springs. Inspect the rotor vanes for wear, scoring, warpage, or other damage. Compare the width of the old vane with a new one to determine the amount of wear that has taken place on the width.
If the old vane is more than 3/64" less than the new vane (in width), it must be replaced. An old vane that shows wear on the thickness must also be replaced.
Vanes worn in this manner will eventually, fail, cause costly repairs, and unexpected down-time on the hoist.
Warped vanes must also be replaced as the vanes must move in and out of the rotor slot without binding.
Inspect leaf springs and centering pins. Worn areas on springs can cause eventual spring breakage and motor lock up. Replace worn springs, particularly when vanes are replaced.
c. Inspect Load Brake and Overload Clutch. Disassemble load brake and clutch assembly as outlined in Paragraph
7-4. Friction discs should be discarded and replaced with new discs. Check load brake friction surfaces on flange, ratchet assembly and gear clutch cone. Replace parts if badly scored or worn. Check condition of pawl and ratchet assembly. If pawl, ratchet teeth or pawl spring are broken, damaged or badly worn, replace complete assembly.
Check contact faces of load brake cam and gear center.
Brake gear and pinion teeth should be inspected for wear or broken teeth. Clean parts thoroughly with an oil solvent before reassembly.
Note: The overload clutch assembly should not be disassembled as it is preset at the factory to provide proper clutch pressure for a specific hoist capacity range.
If there is evidence of the clutch slipping or wear or damage to the clutch components, the complete clutch assembly should be replaced or sent to an authorized
BUDGIT Hoist Repair Station to be rebuilt and properly adjusted to factory specifications.
d. Inspect Sprocket and Intermediate Gears.
(1) Check condition of gear teeth on intermediate gear and pinion shaft assembly. Replace worn or damaged parts.
(2) Check condition of teeth or pockets on chain sprocket.
Replace worn or damaged parts.
e. Reassemble and Test Hoist. Reassemble hoist from subassemblies following procedure outlined in Paragraph
7-9. After assembly is complete, test hoist as outlined in
Paragraphs 7-10 and 7-11.
Figure 5-7. Rotor Vane
(5) Motor Bearings. check motor bearings, especially the bearing at the extended shaft end of the motor, for excessive looseness or binding. Do not, under any circumstances, wash sealed bearings nor blow off with a high pressure air hose. Replace damaged or worn bearings. See Paragraph 7-8.
e. Reassemble and Test Hoist. Reassemble hoist as outlined in Section VII, Paragraph 7-9. After reassembly, test hoist in accordance with Paragraph 7-10.

a. Disassemble Hoist into Subassemblies. Follow procedure outlined in Section VII, Paragraph 7-2.
b. Motor shaft oil seal and "0" ring, sprocket shaft bearing and seal, guide pin "0" rings and all gaskets should be replaced.
SECTION VII - DISASSEMBLY AND REASSEMBLY
7-1. GENERAL.
a. The following disassembly and reassembly instructions apply to all models of BUDGIT Series 6000 Air Hoists.
Where needed, variations to instructions are provided to cover differences between models (suspensions, load chain, reeving, capacity sizes) with applicable models specifically noted.
b. A complete tear down procedure is given. However, if only certain parts require repair or replacement, a partial tear down may be performed, using applicable portions of the instructions.
c. For easier handling during disassembly, the following disassembly steps may, where conditions permit, be completed before hoist is removed from its overhead suspension or disconnected from its air supply: Remove chain container, if hoist is so equipped. Remove lower block and load chain assembly, following procedure outlined in Paragraph 7-2.a. Drain and discard gearcase oil, by removing plug at bottom of frame.
d. These hoists contain precision machined parts and should be handled with care at disassembly and at reassembly.
When removing or installing parts with press fits, be careful to apply pressure evenly. On ball bearings, apply pressure to face of inner or outer race, whichever is adjacent to mating part. This will avoid damage to bearing races from brinelling by pressing through bearing balls.

(4) The load brake pawl and ratchet is a riveted assembly and is not to be disassembled.
b. Reassembly.
(1) Before assembly, all parts should be cleaned and inspected to determine their serviceability. Replace parts that are excessively worn or damaged.
(2) Reassemble load brake parts following a reverse procedure of the disassembly steps listed above, observing the assembly steps (3) through (6) below.
(3) Before installing spring in its recess in center of clutch cone (Figure 7-21) apply a good grade of ball bearing grease to inside of recess. Spring must be positioned exactly as illustrated, butted against pin.
(4) When installing pawl and ratchet assembly on load brake shaft, be certain that teeth on ratchet face are in the same direction as shown in Figure 7-20. The ratchet assembly should rotate freely when turned counterclockwise and the pawl should engage ratchet teeth when unit is turned clockwise.
(5) When installing brake flange position it with chamfer facing friction disc, Figure 7-19.
(6) The brake spring must be pre-loaded at assembly to a torque of from 10 to 14 lb. ft. This is accomplished using a plumber's strap wrench to wind (rotate) load brake gear to set up spring (Figure 722) while pressing brake flange into place using an arbor press. Clamp pinion end of shaft into a portable vise to keep brake from rotating in press. Use brass or copper jaw plates on vise to protect pinion gear teeth. Wind gear counterclockwise (viewing brake from flange end) with plumber's strap wrench and press down on flange until snap ring groove in shaft is exposed allowing snap ring to be installed. Use extreme care not to over wind spring as yield will result and final spring torque will be reduced. Do not wind gear beyond point necessary to install snap
*ring in groove.

Early hoist models utilized a plastic valve and valve base. When rebuilding supply head, replace these with the new valve sleeve, spring, and stem.
b. Reassembly. (See Figure 8-7)
(1) Before assembly, all parts should be thoroughly cleaned and inspected to determine their serviceability.
Replace all parts that are worn or damaged.
(2) Install muffler screen diagonally in cavity with square end resting against back above circular contour and notched end straddling bottom rib near opening.
(3) Install muffling material above screen and mount gasketed cover with screws.
(4) Install valve springs and stems in sleeves and lubricate.
(5) Slide sleeves into position in supply head (small, single hole on side of sleeves must align with retaining screws) and reinstall retaining screws.
(6) Replace supply head gasket. Position gasket so that no portion of ports is covered.
7-8. REBUILD OF AIR MOTOR.
a. General. For removal of supply head assembly and muffler assembly, see Paragraph 7-7.
b. Disassembly.
(1) Remove four hex socket cap screws and then remove motor from hoist.
(2) Remove three fillister head screws, end cap and gasket.
(3) Remove six hex head bolts holding rear end plate to motor cylinder.
(4) Hold the shaft in a soft jawed vise and using a puller, adapted to fit the three #10-32 bolt centers of the end cap, remove rear end plate and shim gasket. Do not try to pry the end plate from the motor.
(5) Remove six hex socket cap screws from front end plate.
(6) Remove motor body exposing the rotor assembly while leaving front end plate mounted on shaft. This relationship should be maintained to eliminate the necessity of adjusting the motor upon reassembly.
(7) Remove vanes, springs, and pins.
Note: Motors requiring further disassembly should be sent to an authorized BUDGIT repair station for repairs.
c. Reassembly.
(1) Before assembly, all parts should be thoroughly leaned and inspected to determine their serviceability. Replace all worn or damaged parts.
(2) Position assembly vertically with rotor facing upward.
Insert push pins in rotor. Place shim gasket and motor body on end plate, using dowel pins for positioning.
Insert vanes and springs into rotor. Take care that spring tab is positioned in slot of vane.
(3) Install six hex socket head screws through front end plate.
(4) Place shim gasket and rear end plate on body, using dowel pints for positioning. Press rear bearing onto rotor shaft by pressing on inner race. Bearing outer race should not be bottomed on rear end plate.
(5) Install six hex head bolts through rear end plate.
(6) Replace end cap and gasket and install three fillister screws.
(7) Position motor in proper orientation on hoist and fasten with four hex socket head screws.
7-9. REASSEMBLY OF HOIST FROM SUBASSEMBLIES.
a. General. The procedure to be followed to reassemble the hoist from subassemblies is in reverse order of the disassembly steps outlined in Paragraph 7-2. Listed below are special precautions which should be observed to assure proper assembly.
b. Assembly of Load Brake Thrust Washers. When reinstalling load brake assembly be certain thrust washers are properly installed at both ends of load brake shaft, as noted below.
(1) A bronze thrust washer with a lug on one side belongs on pinion end of shaft and must be installed so that its lug engages the special slot located on spotface surrounding bearing bore inside gearcase cover. Use heavy grease to hold washer in proper position in cover during assembly.
(2) A 5/8" I.D. steel thrust washer is to be installed on the brake flange end (end opposite pinion) of load brake assembly.
c. Assembly of Load Chain.
Note: Coil chain must be installed so welds on vertical links face away from the load sprocket.
Page 21
(1) Install load chain over sprocket before load brake assembly is installed. Insert anchor end of chain (end opposite lower block on single reeved models) into chain guide opening on far side of hoist (viewing frame from anchor screw side). Rotate sprocket gear by hand counterclockwise as chain is fed into opening. When sufficient chain has been run into hoist to reach anchor position, plus a slack loop, install limit actuator on anchor end of load chain (see (2) below) and attach end of chain to frame with special fillister head screw.
Be certain chain is not twisted.
(2) When installing limit actuator on anchor end of load chain attach it on the ninth link from the end.
(3) When installing limit actuator at lower block, attach to first link above block for single line hoists and third link above block (on chain that dead ends into block) on three line hoists. If single line hoist has a bumper, place it above the limit actuator.
d. Lubricate Hoist. Lubricate hoist as outlined in Section IV.
7-10. TESTING HOIST.
a. General. After completion of reassembly and before placing hoist in service, hoist should be tested to insure safe operation. To test: suspend hoist from an overhead supporting member of sufficient strength to carry rated load; connect to an air supply of the specified capacity and perform the following checks and adjustments.
(2) When installing limit actuator on anchor end of load chain attach it on the ninth link from the end.
(3) When installing limit actuator at lower block, attach to first link above block for single line hoists and third link above block (on chain that dead ends into block) on three line hoists. If single line hoist has a bumper, place it above the limit actuator.
d. Lubricate Hoist. Lubricate hoist as outlined in Section IV.
7-10. TESTING HOIST.
a. General. After completion of reassembly and before placing hoist in service, hoist should be tested to insure safe operation. To test: suspend hoist from an overhead supporting member of sufficient strength to carry rated load; connect to an air supply of the specified capacity and perform the following checks and adjustments.
b. Check that load hook will travel in the correct direction when up and down levers are depressed. Make correction, if necessary, by interchanging the two supply hoses at the pendant station. Upper ends of each supply hose are made to "nest" one above the other. Down supply hose has a speed adjustment screw as part of the elbow fitting.
c. Check Upper and Lower Limit Stop Operation. To determine if upper and lower limit stop functions properly, make the following checks.
(1) Depress "UP" lever and inch limit actuator (on single reeved models) or lower block up into limit stop to see that clutch will slip.
(2) Depress "DOWN" lever and inch limit actuator up into limit stop to see that clutch will slip.
d. Check Hoist With Capacity Load. Attach rated capacity load (or load to be handled) to lower hook and check hoist operation. If hoist does not lift rated load, refer to
Paragraph 7-11.
(1) Operate hoist to raise load. When control is released, hoist should stop and hold load at that level.
(2) Operate hoist to lower load a short distance, then release control. Hoist should stop and hold load at that level.
(3) If hoist does not stop or hold load refer to Section VI.
e. Adjust speed of lowering with load to be handled, as required, by positioning screw in elbow fitting of down supply hose.
7-11. TEST PROCEDURE FOR CHECKING OPERATION OF
OVERLOAD CLUTCH.
a. General. The overload clutch must be tested using known weights. The following prerequisites (Paragraphs (1) through (4)) must be strictly observed in performing this test.
(1) A qualified person shall determine before testing, that all structures supporting the hoist are adequately strong to withstand the test load of 200 percent of rated hoist load, whether hoist is tested in installed position or moved to a designated test facility.
(2) Loads used for testing must be accurately known.
(3) Test shall be made only by a qualified operator thoroughly familiar with the hoist and the purpose of the test.
(4) Provide adequate and proper rigging to insure test loads are securely attached, properly balanced, and will lift level.
b. Test Procedure. With the above prerequisites satisfied and hoist properly connected to air supply, proceed with the test as follows:
(1) Using a known load equal to rated load of hoist, operate hoist to lift load. Raise load high enough to be certain the entire load is freely suspended. Clutch
should not slip at rated load. If hoist does not lift rated load, clutch requires adjustment. Refer to Section
V, Paragraph 5-5.c.
(2) Increase load to 200 percent rated load and operate hoist to lift the load. Clutch must slip, causing the hoist to refuse to lift the load. If hoist lifts this overload, the overload clutch is out of adjustment and must be readjusted. Refer to Section V, Paragraph 5-5.c.
(3) If clutch slips as required in step (2) above, continue to run hoist (clutch slipping - hoist refusing to lift load) for no more than five (5) cycles of one (1) second each.
(4) Remove excess weight to return the load to rated hoist load. Lift rated load one final time to be certain that the clutch does not slip and that the hoist lifts the rated load.
Page 22
WARNING
DO NOT LIFT MORE THAN RATED LOAD EXCEPT FOR TEST PURPOSES
