Troubleshooting Checklist

1. Hose fittings loose, worn or  
 damaged.

2. Oil seal rings (3) deteriorated by 
  excess heat.

3. Special bolt (1, 1A, 1B or 1C)  
  loose or its sealing area  
  deteriorated by corrosion.

4. Internal shaft seal (14) worn or 
 damaged.

5. Worn coupling shaft (10) and 
  internal seal (14).

Oil Leakage

Check & replace damaged 
fittings or “O” Rings. Torque to 
manufacturers specifications.

Replace oil seal rings by disassembling 
Torqmotor™ unit.

(a)  Loosen then tighten single bolt to 
 

torque specification.

(b)  Replace bolt.

Replace seal. Disassembly of Torqmotor™ 
unit necessary.

Replace coupling shaft and seal by  
disassembling Torqmotor™ unit.

Significant loss of 
speed under load

1. Lack of sufficient oil supply

2. High internal motor leakage

3. Severely worn or damaged 
  internal splines.

4. Excessive heat.

(a)  Check for faulty relief valve and  
 

adjust or replace as required.

(b)  Check for and repair worn pump.

(c)  Check for and use correct oil for  
 

temperature of operation.

Replace worn rotor set by disassembling 
Torqmotor™ unit.

Replace rotor set, drive link and coupling 
shaft by disassembling Torqmotor™ unit.

Locate excessive heat source (usually a 
restriction) in the system and correct the 
condition.

Low mechanical  
efficiency or  
undue high pressure 
required to operate 
Torqmotor™ unit

1. Line blockage

2. Internal interference

3. Lack of pumping pressure

4. Excessive binding or loading in 
  system external to Torqmotor™  
 unit.

Locate blockage source and repair or 
replace.

Disassemble Torqmotor™ unit, identify and 
remedy cause and repair, replacing parts 
as necessary.

Check for and repair worn pump.

Locate source and eliminate cause.

CAUTION: If the hydraulic system fluid becomes overheated [in excess of 200°F (93.3°C)], seals in the 
system can shrink, harden or crack, thus losing their sealing ability.
