PROBLEM
POSSIBLE CAUSE
CORRECTION ACTION
Winch Operates But Exhibits The Following Problems
Winch operates in
LINE-
IN
only.
Brake shuttle stuck.
Check for debris.
Counterbalance valve pilot
signal blocked or connected
to drain.
Check for plugged control manifold passage or missing
manifold plug.
Counterbalance valve
damaged or set incorrectly.
Adjust or replace counterbalance valve.
Malfunction in the ripper
control circuit.
Troubleshoot circuit per tractor service manual.
Winch operates in
LINE-
OUT
only.
Brake shuttle stuck.
Check for debris.
Malfunction in the ripper
control circuit.
Troubleshoot circuit per tractor service manual.
Winch will not generate
suffi cient line pull.
Tractor implement pump relief
set too low.
Check tractor hydraulic system settings.
Worn or damaged components
in the gear train.
Visually Inspect to identify damaged components. Repair
and replace as necessary.
Brake not releasing due to
insuffi cient brake release pres-
sure or leak in brake.
Check that brake release pilot pressure is more than 200
psi in
LINE-IN
and
LINE-OUT
functions. If pilot pressure
is too low, check for leaks, faulty control lever, or insuf-
fi cient pilot supply pressure. See Step By Step Pump
and Controller Troubleshooting section in this chapter. If
brake is leaking, repair as needed.
Brake shuttle valve stuck.
Clean or replace as necessary.
Leak in hydraulic system other
than brake assembly.
Plug brake line and check that pressure at motor ports
A & B (See Hydraulic System Pressure Check Tables).
Leak in motor speed spool re-
lief cartridge (
HI-SPEED
only).
Check that the pressures at motor test ports A & B are
suffi cient for operating the winch in
LINE-IN/OUT
with the
brake line plugged. If the pressure is low and registered
simultaneously at A and B, leakage is occurring past the
relief valve. Remove and repair the valve.
Clogged fi lter.
Tractor fi lter indicator light will illuminate if fi lter is clogged.
Replace fi lter. Refer to tractor specifi cations.
Wrong oil.
Use correct oil grade; refer to tractor oil specifi cations.
Low oil level in reservoir.
Add oil; refer to tractor oil specifi cations.
Damaged freespool compo-
nents may be causing winch
to be stuck in
FREESPOOL
.
Inspect freespool shaft for wear or damage, repair or
replace as necessary.
Drag brake piston stuck.
Remove drag brake cover to determine if piston is stuck
and not releasing the drag brake clutch.
Motor damaged.
Repair or replace motor.
