The winch runs hot.

1. The winch may be mounted on an uneven or flexible surface which causes distortion of the winch base and binding of the gear train. Binding in the gear train will absorb horsepower needed to hoist the rated load and cause heat.

   Reinforce mounting surface.
   
   If necessary, use shim stock to level winch. Refer to "Winch Installation" section of the service manual.
   
   First loosen, then evenly retighten all winch mounting bolts to recommended torque.

2. Be certain hydraulic system temperature is not more than 180 degrees F. Excessive hydraulic oil temperatures increase motor internal leakage and reduce motor performance.
   
   Excessive hydraulic oil temperatures may be caused by:
   
   
   1. Plugged heat exchanger.

      Thoroughly clean exterior and flush interior.

   2. Too low or too high oil level in hydraulic reservoir.

      Fill/drain to proper level.

   3. System relief valve may be set too low. Relief valve needs adjustment or repair.

      Check relief pressure as follows:
      
      

      1. Install an accurate 0-4000 psi (27,580 kPa) gauge into the inlet port of the brake valve.
         
      2. Apply a stall pull load on the winch while monitoring pressure.
         
      3. Compare gauge reading to winch specifications. Adjust relief valve as required.
         

      
      NOTE: If pressure does not increase in proportion to adjustment, relief valve may be contaminated or worn out. In either case, the relief valve may require disassembly or replacement.

3. Hydraulic pump not operating efficiently.

   Prime mover low on horsepower or R.P.M. Tune/adjust prime mover. Check suction line for damage.
   
   If pump is belt driven, belts are slipping. Replace/tighten belts.
   
   Pump worn. Replace pump.

4. Excessively worn or damaged internal winch parts.

   Disassemble winch to inspect/replace worn parts.
