1.
PROBLEM:
Winch won’t hold load.
SOLUTION:
a. Excessive back pressure in the system. Check the system for restrictions and reduce the
backpressure.
b. Brake discs are worn out. Replace brake discs.
c. Winch clutch is slipping. Inspect the clutch and driver for wear and replace worn parts.
2.
PROBLEM:
Winch will not raise the load it should.
SOLUTION:
a. Relief valve setting may be too low to allow proper lifting. Increase relief valve pressure
setting.
(Note: do not exceed recommended system pressures).
b. Load being lifted may be more than the winch’s rating. Reduce the load or re-rig to
increase mechanical advantage.
3.
PROBLEM:
Oil leaks from the vent on the motor side of the winch.
SOLUTION:
a. The motor shaft seal may have failed. Replace this seal and reduce backpressure if that
caused the shaft seal to fail.
b. Brake piston seals may have failed. Service the brake section and replace worn parts.
