5. Remove the brake cylinder assembly (500) after loos-
ening and removing the twelve capscrews (12) and
lockwashers (14) securing it to the ring gear (65). The
brake cylinder pilots on the inner diameter of the ring
gear and must be pulled straight out to prevent bind-
ing.
6. Remove the primary sun gear (2), thrust washer (4),
and the primary planet carrier assembly (200).
7. Remove the secondary sun gear (3) and the second-
ary planet carrier assembly (300) from the ring gear
(65).
8. Remove the output sun gear (64) and output planet
carrier assembly (400).
9. Remove the retaining ring (36) from the drum shaft in
the primary housing and remove the output adapter
(72).
10. Secure the ring gear (65) with eye-bolts, an overhead
hoist, and rigging in preparation for removing the ring
gear (65) and motor-end bearing support (34). Slowly
remove the six capscrews (77), nuts (79), and lock-
washers (78) that secure the motor-end bearing sup-
port to the base-angles and lift the ring gear and mo-
tor- end bearing support off of the drum shaft.
11. Remove the seal container (60) and the thrust washer
(82) from the drum shaft.
12. Secure the winch drum with lifting straps or a lifting
fi xture and use an overhead hoist to remove the drum
from the drum shaft.
13. Remove the drum shaft (1) from the support end bear-
ing leg (38) and remove the sliding clutch (101), spac-
er (81), and retaining ring (75).
14. Set the base angles (73 and 74) onto the ground and
remove the support end bearing leg (38), band brake
(104), and air cylinders (5 and 6) if necessary.
See the subassembly service section in this manual for
disassembly and reassembly procedures for the brake
cylinder, the three planet carrier subassemblies, the over-
running clutch, and the hydraulic motor subassembly.

If the winch cannot be set on the support end, but must
be serviced with the winch on the base angles, remove
the brake cylinder assembly slowly and carefully. The
primary planet carrier (200), primary sun gear (2), thrust
washer (4), and secondary sun gear (3) can fall be-
tween the brake cylinder and the ring gear as the brake
cylinder is removed. Failure to take precautions to pre-
vent parts from falling as the brake cylinder is removed
from the winch may result in personal injury or property
damage.
CAUTION
The HP125B winch drum weighs approximately 400
lbs (182 kg). Ensure all lifting equipment including the
overhead hoist and rigging have adequate capacity.
Use of lifting equipment that does not have adequate
lifting capacity or is not properly maintained may result
in personal injury or death.
The winch drum shaft weighs about 142 lbs (65 kg).
Ensure the hoist and rigging are rated for this weight.
Using a hoist or rigging with insuffi cient rating may re-
sult in personal injury or death.
The winch base angles and bearing leg weighs about
320 lbs (145 kg). Ensure the hoist and rigging are rated
for this weight. Using a hoist or rigging with insuffi cient
rating may result in personal injury or death.
