TROUBLESHOOTING GUIDE

POSSIBLE CAUSE
Winch not mounted squarely, causing end

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.

Low hydraulic system flow rate
Low hydraulic system relief pressure setting
Damaged brake o-rings, backup rings, or
sealing surfaces
CORRECTION/ACTION
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 the 12,7 mm (.50 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.
