CAUTION
• Ensure the reduction gear oil is drained before disassembly
and that the drain and fill plugs are removed. When using
jacking bolts, ensure the cover lifts evenly by turning bolt
one full turn and then repeating on the other bolt. If cover
jams, remove jacking bolts and gently tap around the cover
to reseat it before starting over. Careful prying of the cover
along its diameter during jacking, using a soft material
wedge, to guide the cover is acceptable. Care must be taken
not to scar, gouge or damage the machined finishes on the
cover and the reducer housing mating surfaces during parts
separation.
14. Stand drum on end with reduction gear on top. Remove
reduction gear assembly from drum (62) by removing six
capscrews (32) attaching end cover (33) to drum. Screw
two 7/16 - 20 UNF x 1-1/2 inch capscrews into the
threaded holes in cover (33). Turn both screws evenly until
cover is separated from housing. Remove cover.
15. Screw two 1/2 - 13 UNC x 1-1/2 inch capscrews into the
threaded holes in the reducer housing (59). Turn both
screws evenly until housing is separated from drum. Attach
suitable lifting eyes to the capscrews and remove housing
from drum.
16. To further disassemble reduction gear refer to ‘Reduction
Gear Disassembly’ section.
Control Valve and Inlet Manifold Removal
Refer to Dwg. MHP1314.
1.
Disconnect main air supply line at the winch.
2. Disconnect disc brake air line from the elbow (319) fitting
located on the control valve.
3. Remove capscrews (331) and lift off control valve assembly
(260) and gasket (248).
4. Remove capscrews (614) and lift manifold cover (607) and
manifold (606) from motor housing (220). Manifold and
cover are Loctited together and should not be separated
unless repairs are required to one of the parts.
5. Remove and discard gasket (611).
Control Valve Disassembly
Refer to Dwg. MHP1314.
NOTICE
• Match mark control valve parts to ensure proper
reassembly.
1. Remove the two capscrews (302) and lockwashers (304)
that hold the valve body retainer (305).
2. Mark the square end on the valve body (316) and the
handle (300) to ensure correct orientation during re-
assembly.
3. Drive out pin (301) and remove handle (300).
4. Note how spring (303) is positioned before removing it.
Pull valve body (316) out of the valve bushing (314) while
disconnecting the spring (303).
5. Remove seal rings (315) from valve body (316).
6. Check parts for score marks or wear.
7. Measure clearance between the valve bushing (314) and
valve body (316). Clearance between valve bushing and
valve body should not exceed 0.002 inch (0.05 mm) or
excessive air leakage will occur.
Remote Control Valve and Inlet Manifold Removal
Optional feature. Refer to Dwg. MHP1304.
1.
Disconnect main air supply line at the winch.
2. Disconnect disc brake air line from connector fitting (621)
located on valve assembly (355).
3. Disconnect pendant hoses from valve assembly.
4. Remove capscrews (608) and lift off valve (355) and cover
(607) assembly.
5. Remove capscrews (615) and separate cover (607) from
valve assembly (355).
6. Remove capscrews (614) and lift manifold (606) from
motor housing (220).
7. Remove gasket (611).
Motor Disassembly
Refer to Dwg. MHP1310.
NOTICE
• Internal components of the motor are machined to very
close tolerances. Ensure that work area and parts are kept
very clean to prevent damage or contamination to
components.
1. Disconnect air line to winch.
2. Remove muffler (234) as an assembly.
WARNING
• The air motor weighs approximately 100 lbs. (45.3 kg).
Adequately support the air motor before removing the motor
mounting capscrews.
3. Use a nylon sling and suitable hoist to support the motor
assembly.
4. Remove capscrews (221) and pull motor straight away from
motor adapter (71).
5. Place motor on a suitable clean bench with air inlet facing
up.
6. Refer to ‘Control Valve Disassembly’ for manifold
removal.
7. Remove capscrews (224) and pull exhaust manifold (233)
off of motor housing.
8. Tip motor onto the open end. Remove capscrews (224) and
pry cover (223) off of motor housing (220).
9. Remove setscrew (218) and loosen capscrew (216) and
locknut (217). Pull counterweight (214) off of crankshaft
pin (213).
10. Remove capscrews (229) from caps (226) and (227) and
remove cylinder assemblies.
11. Rotate crankshaft slowly until the flat portion of the piston
assembly (240) can be lifted into the square portion of the
cylinder port in the motor housing. Lift the piston assembly
off the crankshaft pin (213) and slide back out through the
motor housing.
12. Repeat this operation for the other piston assembly.
13. Push spool (231) out of motor housing (220). Remove and
discard ‘O’ rings (230).
CAUTION
• Use a press to remove the following components. DO NOT
use a hammer to remove parts as this can cause damage to
the link rod and piston rod.
