TROUBLE
PROBABLE CAUSE
REMEDY
D
Winch will not pull the rated load. 1. The hydraulic system relief valve
may be set too low. The relief
valve may need repair or replace-
ment.
2. Be certain the hydraulic system
temperature is not more than
200ºF (93ºC). Excessive hydraulic
oil temperatures increase motor
and pump internal leakage.
3. Winch line pull rating is based on
first layer of wire rope.
4. Same as C5.
5. Hydraulic motor locked in high
speed, small displacement posi-
tion.
A. Check system relief pressure as fol-
lows:
Install an accurate gauge into the trac-
tor pump pressure port per the tractor
manual.
Apply a stall pull load on the winch while
monitoring the pressure.
Compare the gauge reading to the winch
specifications. Adjust the relief valve as
required, if necessary.
NOTE:
Refer to the tractor service man-
ual for more information regarding the
system relief valve.
A. Check system relief valve, per D1A.
B. Same as E2A.
A. Refer to winch performance data for
more information.
