Winch Assembly
All components should be inspected for wear or damage
as they are removed. Refer to Figure 4-8, Visual Inspection.
All seals that were removed should be replaced during
assembly. Carefully inspect all bearings that have been
removed. Used bearings often appear satisfactory, but
may fail when placed under a load. When in doubt, it is
recommended to install a new bearing. Any component
that indicates excessive wear or damage should be
replaced. The following reassembly and installation
sequence assumes a complete winch overhaul.

ITEM
INSPECTION REQUIREMENTS
CORRECTIVE ACTION
Brake Assembly
Check for cracked or broken belleville/coil
springs.
Replace springs if cracked or broken.
Inspect housing and covers for leakage or
damage.
Replace component if sealing surfaces or splines
are damaged.
Check the rotor discs for wear, distortion,
or damage. The discs should be free of
hydraulic oil.
Replace the rotor discs if the wear grooves are
worn away, the discs are burned, damaged,
warped, or exposed to oil. Brake cleaner may
be used to clean dust from the discs but will not
remove impregnated oil.
Check the brake/motor shaft seals for
leakage into the brake housing.
Replace damaged seals.
Inspect the brake/motor shaft for wear or
damage.
Replace a damaged shaft.
Check that the stator discs are flat, free of
large blue areas (caused by overheating)
or damaged surfaces.
Replace damaged stator discs.
Inspect the piston for damage. Make sure
the seal groove and sealing surfaces are
in good condition.
Replace a damaged piston. Always replace the
piston seals when the brake is repaired.
Planetary Speed
Reducer
Check the housing for leakage or damage. Repair or replace assembly.
Check output shaft bearing end play.
End play is 0.000-0.006”. End play is adjusted
using the appropriate thickness retaining ring.
See parts manual.
Inspect sun gear and carrier assembly for
damage or wear. Sun gear should spin
freely in carrier assembly.
Replace assembly.
Winch Motor
Inspect motor shaft seal for wear or
damage.
Note: A leaky motor shaft seal will contaminate
the brake with oil and the brake will likely require
service. Replace seal.
