Troubleshooting
General
Winch problems fall into one of three categories: control
system, hydraulic system or mechanical system. Follow
the troubleshooting steps below to isolate the problem
area.
1. Be sure the tractor hydraulic system is working
properly. Verify that other implements, such as blade
functions, are operating properly.
2. Make sure the winch electrical system is functioning
properly.
3. Check winch hydraulic pressures. See Service section
of this manual to perform Hydraulic System Pressure
Checks.
4. Inspect the winch gear train for mechanical problems.
Mechanical/Hydraulic Troubleshooting
For proper hydraulic troubleshooting, the winch oil oper-
ating temperature should not exceed 180°F (82°C). Oil
reservoir temperature is monitored at the dozer.
NOTE: Please refer to the Safety Summary before
performing any troubleshooting or maintenance on
the winch.
PROBLEM
POSSIBLE CAUSE
CORRECTION ACTION
Winch Does Not Operate with the Tractor Running
Hydraulic power not being
supplied to winch.
Tractor work equipment lever is in
locked position.
Unlock tractor work equipment lever.
Improper winch hose routing.
Verify hose connections are in accordance
with hydraulic schematic and installation
instructions for specifi c application.
Low oil.
Check for proper oil level.
No pilot pressure (PS).
Tractor work equipment lever is
locked.
Unlock tractor work equipment lever.
Improper winch hose routing.
Verify hose connections are in accordance
with hydraulic schematic and installation
instructions for specifi c application.
Low pilot pressure (PS).
Improper tractor pilot supply setting
or malfunction.
Refer to tractor pilot system troubleshooting.
Brake not releasing.
No or low brake release pressure.
Check pilot pressure.
Check hoses for leaks.
Brake valve out of adjustment or
damaged.
Perform brake valve pressure checks and
adjust as specifi ed. Remove valve and
inspect for debris or damage. Replace valve
as necessary.
Improper winch hose routing.
Verify hose connections are in accordance
with hydraulic schematic and installation
instructions for specifi c application.
Brake mechanical damage.
