AT NO LOAD
DRUM WILL NOT ROTATE
UNDER LOAD
WINCH RUNS TOO SLOW
DRUM WILL NOT
FREESPOOL
BRAKE WILL NOT HOLD
LOAD DRIFTS
ROPE BIRDNESTS WHEN
CLUTCH IS DISENGAGED
EXCESSIVE NOISE
DRUM CHATTERS IN
"REEL IN" DIRECTION
OIL LEAKS FROM
BREATHER VENT UNDER
MOTOR END BEARING
POSSIBLE CAUSE
Winch not mounted squarely, causing end bearing
to bind up
Gears damaged
Winch not mounted squarely, causing end bearing
to bind up
Load greater than rated capacity of winch
Low hydraulic system pressure
Low hydraulic system flow rate
Motor worn out
Clutch not disengaged. Check Adjustment of Manual
Shifter, page 9.
Winch not mounted squarely, causing end bearing
to bind up
Side mounted bolts too long, causing binding of ring
gear (Item #15, page 14).
Incorrect directional control valve (cylinder spool-
closed center)
Excessive Backpressure 6,9 bar (100 PSI) Max.
Drag screw improperly adjusted
Hydraulic system flow too high
Drum in bind, winch not mounted squarely
Low hydraulic system flow rate
Low hydraulic system relief pressure setting
Damaged brake o-rings, backup rings, or sealing
surfaces
Check mounting. Refer to Winch Mounting, page 4.
Inspect and replace damaged gears
Check mounting. Refer to Winch Mounting, page 4.
Refer to Specifications page 3 for line pull rating.
Check pressure. Refer to Hydraulic Systems
performance charts page 6.
Check flow rate. Refer to Systerm Requirements and
Typical Layout page 6.
Replace motor
Check Operation, page 5.
Check mounting. Refer to Winch Mounting, page 4.
Check bolt length. Bolt thread MUST NOT engage
threaded holes in sides of end bearing more than
between 12,7 mm (.50 in) and 17,5 mm (.68 in)
thread depth in the end bearing.
Use only a motor spool (open center) control valve.
Check for restrictions in hydraulic system. Refer to
System Requirements and Typical Layout page 6.
Adjust nylon drag screw. Refer to Rope Installation,
page 4.
Check flow rate. Refer to Typical Layout page 6.
Check mounting. Refer to Winch Mounting, page 4.
Check flow rate. Refer to Typical Layout page 6.
Check relief valve setting.
Disassemble brake and inspect. See Overhaul
Instructions, pg. 8.
