TROUBLE SHOOTING
TROUBLE
REMEDY
PROBABLE CAUSE
If a winch ever exhibits any sign of erratic operation, or load control difficulties (i.e. load creeping or chattering)
appropriate troubleshooting tests and repairs should be performed immediately. Continued operation in this manner
may result in property damage, serious personal injury or death.
A
The winch will not pay-out or haul-in
the load smoothly.
CAUTION
WARNING
!
!
Disassemble brake to inspect
brake discs.
2.
Friction brake will not release as
a result of damaged brake
discs.
Check brake cylinder seal as
follows:
A. Disconnect the hose from the
brake valve block. Connect a
hand pump with accurate 0-
2,000 psi (13,800 kPa) gauge
and shut-off valve to the hose
(–4 J.I.C. fitting).
B. Apply 1,000 psi (6,900 kPa) to
the brake. Close shut-off valve
and let stand for five (5) min-
utes.
C. If there is any loss of pressure in
five (5) minutes, the brake cylin-
der should be disassembled for
inspection of the sealing sur-
faces and replacement of the
seals. Refer to “Motor Support-
Brake Cylinder Service”.
1.
The friction brake may not be
releasing as a result of a defec-
tive brake cylinder seal.
NOTE: If the brake cylinder seal
is defective the winch drum will
fill with hydraulic oil and slowly
fill the chain case. A fast leak
may cause oil to leak around the
motor end drum seal. A slower
leak may fill the chain case and
leak oil from the vent.
Oil leaks from vent plug.
Same as A1.
Peak intermittent system back
pressure must not exceed 150
psi (1,030 kPa). Inspect
hydraulic system for a restriction
in the return line from the control
valve and/or from the motor
case drain to the reservoir. Be
sure control valve and plumbing
is properly sized to winch motor.
Oil analysis may indicate con-
tamination has worn motor shaft
and seal. Thoroughly flush
entire hydraulic system and
install new filters and oil. Install
new motor seal.
1. Same as A1.
2. Motor seal may be defective as a
result of high system back pres-
sure or contaminated oil.
