Troubleshooting Checklist Trouble Cause Remedy Oil Leakage 1.  Hose fittings loose, worn or damaged Check & replace damaged-fittings or "O" Rings.  Torque to manufacturers specifications. 2.  Oil seal rings (7) deteriorated by Replace oil seal rings by excess heat disassembling Torqmotor   unit. 3.  Special bolt (24) loose or its sealing (a).Loosen then tighten single bolt to area deteriorated by corrosion 45-55 ft.lbs.  (60-76 N m) (b) Replace bolt. 4.  Internal shaft seal (5) worn or Replace seal.  Disassembly of damaged Torqmotor   unit not necessary. 5.  Worn coupling shaft (11) and internal Replace coupling shaft and seal by seal (5) disassembling Torqmotor   unit. Significant loss of speed under 1.  Lack of sufficient oil supply (a) Check for faulty relief valve and load adjust or replace as required. (b) Check for and repair worn pump. (c) Check for and use correct oil for temperature of operation. 2.  High internal motor leakage (a) Replace worn rotor set by disassembling Torqmotor TM unit. 3.  Severely worn or damaged internal Replace rotor set, drive link and splines coupling shaft by disassembling Torqmotor TM unit. 4.  Excessive heat Locate excessive heat source (usually a restriction) in the system and correct the condition. Low mechanical efficiency or 1.  Line blockage Locate blockage source and repair undue high pressure required to or replace. operate TorqmotorÔ   unit 2.  Internal interference Disassemble Torqmotor TM unit, identify and remedy cause and repair, replacing parts as necessary. 3.  Lack of pumping pressure Check for and repair worn pump. 4.  Excessive binding or loading in system Locate source and eliminate external to MAB/MAE unit. 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.
