Together, remove the second reduction pinion and first
reduction gear from the winch case. Press the pinion from
the gear and bearings.
Inspect the bushing in the first reduction gear for scoring
or excessive wear. The bushing should fit freely over the
pinion.
Inspect the bearing cup in the inner case wall and replace
as required.
FREESPOOL CYLINDER ASSEMBLY SERVICE
Remove the capscrew, retainer washer, springs and
spring guides.
Remove the cylinder rod from the cylinder.
Inspect the sealing surfaces for scoring or other abnormal
wear and replace components as required. Use new O-
rings when reassembling.
Apply Loctite 242, or equivalent, to clean, dry threads of
the capscrews during reassembly.
ASSEMBLY
Place the second reduction pinion on a flat surface with
the small diameter end facing upward.
Lubricate the bushing and mating surfaces of the second
reduction pinion with new winch oil, and install the bush-
ing over the pinion.
Install the freespool clutch collar over the first reduction
gear with the beveled side of the collar facing down
toward the large end of the pinion.
Lubricate the outside diameter of the bushing and the first
reduction gear bore with new winch oil. Install the first
reduction gear and clutch collar assembly over the bush-
ing, aligning the second reduction pinion teeth with the
splined collar teeth. The clutch collar MUST be installed
with the chamfered edge toward the pinion.
Install the thrust washer over the second reduction pinion
and into the recess of the first reduction gear.
Press the inner bearing cone over the end of the second
reduction pinion, until the bearing cone is resting firmly
against the thrust washer.
Press the outer bearing cone over the end of the second
reduction pinion, until the bearing cone is resting firmly
against the pinion shoulder.
If required, lubricate and install the bearing cup into bore
in the inner wall of the winch case.
Place the first reduction gear and second reduction pinion
assembly into the winch case opening, aligning the inner
bearing cone within the bearing cup.
If required, install the cylinder stud into the winch case.
Use Loctite 242, or equivalent, on clean, dry threads.
Install the freespool cylinder assembly into the winch
case. Engage the clutch collar with the yoke. Rotate the
cylinder assembly into alignment with the cylinder stud.
BE SURE the roll pin in the stud engages the hole in the
cylinder assembly.
Install the capscrew, spring and retainer. Apply Loctite
242, or equivalent, and torque to 45 lb•ft (61 N•m).
