11. On standard winch: using a hoist to support the drum,

remove sideframes (64) and (65), one at a time, by
removing four capscrews (66) attaching each sideframe to
uprights (26) and (68).

12. On Open Frame (Face) winch: To assist reassembly,

record the number and location of washers (584) installed
between the sideframes (571) and (573) and bars (570).
Using a hoist to support the drum, remove rear sideframe
(64) by removing four capscrews (66) attaching sideframe
to uprights (26) and (68). Remove front bars (570) and
sideframes (571) and (573) as an assembly by removing
four capscrews (574) and washers (584). To separate bars
from sideframes, remove capscrews (572). Refer to Dwg.
MHP1324.

13. Remove the inboard (motor end) upright (68) by pulling

straight away from drum (62) in a horizontal direction.
Remove oil seal (29) and bearing (30) from upright.
Discard oil seal. Discard bearing if inspection indicates
replacement.

14. If equipped, remove the drum band brake assembly (104)

by sliding over the end of the drum (62) flange. To further
disassemble the drum brake, refer to the appropriate
‘Manual Drum Band Brake Disassembly’ or ‘Automatic
Drum Band Brake Disassembly’ section.

15. Remove the outboard (disc brake end) upright (26) by

pulling straight away from drum (62) in a horizontal
direction. Remove oil seal (29) and bearing (30) from
upright. Discard oil seal. Discard bearing if inspection
indicates replacement.

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.

16. 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.

17. 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.

18. 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.

(260) and gasket (321).

4.

Remove capscrews (614) and lift manifold cover (607) and
manifold (606) from motor housing (220). Manifold and
cover are bonded together and should not be separated
unless repairs are required to one of the parts.

5.

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).

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.

8.

Remove the two capscrews (302) and lockwashers (304)
attaching flange (318) to valve body.

9.

Remove flange and gasket (317). Discard gasket.
