ITEM
INSPECTION REQUIREMENTS
CORRECTIVE ACTION
Winch Motor
Inspect motor shaft seal for wear or dam-
age.
Note: A leaky motor shaft seal will contaminate the
brake with oil and the brake will likely require service.
Replace seal.
Inspect vanes for wear or damage.
Normal wear results in slight fl attening of vane tips,
which does not impair motor performance. Replace
vanes if radius is reduced by 50%.
Inspect plates for wear or damage.
Normal wear results in marking of timing plates which
does not impair motor performance. Replacement of
the timing plate is required if any smearing, galling,
or heat cracks are present.
Inspect stator for wear or damage.
Normal wear results in polishing of cam form which
does not impair motor performance. Noticeable wear
may be apparent along the corner of one side of the
vane slot. This does not require replacement of the
stator, but may slightly affect volumetric effi ciency.
Freespool Shifter Check oil level in winch is not over full. This
is an indication that the freespool hose or
piston seals are leaking.
Tighten or replace freespool shifter hose. Replace
piston seals.
Freespool Dental
Clutch
Check for broken or worn teeth.
Replace dental clutch if teeth are broken or severely
worn.
I n t e r m e d i a t e
Shaft
Check for deep scratches or scoring on
bearing surfaces at each end of shaft.
Dress surface or replace shaft if severely worn.
Check for broken or severely worn splines. Replace if splines are broken or severely worn.
I n t e r m e d i a t e
Gears
Inspect both gears for broken or severely
worn teeth. Pay particular attention to lead-
ing edges of straight-cut gear teeth.
Replace gears if teeth are broken or severely worn.
Drum Shaft
Check for deep scratches or scoring on
bearing surfaces.
Dress surface or replace shaft if severely worn.
Check O-ring groove and seal surface.
Dress groove or replace shaft if severely worn.
Check for crossthreaded or damaged
threads.
Dress threads with thread chaser.
Drum Gear
Check for broken or severely worn gear
teeth. Pay particular attention to leading
edges of straight-cut gear teeth.
Replace gear if teeth are broken or severely worn.
Drum
Inspect quad-ring groove for burrs, scoring
and rust.
Replace drum or rebuild drum groove if a new quad-ring
will not seat properly.
Drum Adapter
Carefully inspect double seal contact sur-
face for deep scratches, burrs and rust.
Replace if damaged.
Winch Frame
Check area around drum and drum adapter
for damage if cable has slipped between
cable guard and winch frame.
Consult the factory.
