PROBLEM POSSIBLE CAUSE CORRECTION
Low forward or reverse
clutch pressure
Leak in hydraulic system, or loose
hydraulic connections.
Visually inspect winch for leaks, and ensure
hydraulic connections are secure.
Leaky clutch circuit. Perform clutch bleed-down test on clutch circuit.
Broken or worn seal rings on the
bevel gear shaft.
Replace seal rings.
NOTE: A broken seal ring is the most common
cause of a pressure differential between the two
clutches. Check preload on clutch/brake shaft
and adjust it if necessary to prevent additional
breakage of seal rings; refer to Section 4 in
Service Manual.
Damaged bevel gear shaft seal
ring grooves.
Check grooves for taper, scoring and rust. Replace
or rebuild shaft if surfaces between the inner side
of groove and seal ring are not fl at.
Damaged bevel gear shaft bearing
retainers.
Check retainer for grooves. Replace retainer if
defective, or re-sleeve.
Damaged clutch piston, piston
retainer or O-rings.
Check piston and piston retainer cavity for
damage. Always replace both O-rings when clutch
is repaired. Refer to Section 4 in Service Manual.
Reverse pressure hose damaged
by bevel gear.
Remove cover and inspect.
