The D65 (D65EX / D65PX / D65WX series) uses an electro-hydraulic static cooling fan system (HSS). The fan motor is the hydraulic motor within this system—driven by pressure oil supplied from the engine-mounted fan pump (gear pump), replacing the conventional mechanical belt drive. Its speed is electronically regulated to precisely control the cooling fan rotation.

Core Function

Drives the cooling fan to dissipate heat from the engine and hydraulic system. It automatically reduces speed at idle or low temperature to save fuel and reduce noise, and increases speed under high temperature or heavy load to ensure adequate cooling.

Common Faults & Troubleshooting
  • Fan not rotating / abnormal speed: First determine whether the fault is in the pump or the motor—measure the fan motor inlet pressure/flow. If pressure is normal but the fan does not turn, it indicates internal motor wear; if pressure or flow is insufficient, check the fan pump, filter and oil circuit.
  • Abnormal noise / squealing: Worn internal motor bearing, cavitation (air entrained in system), contaminated oil.
  • Unstable fan speed / jitter: Abnormal electronic control signal, seized motor displacement mechanism, air in oil circuit.
  • Oil leakage: Aged shaft oil seal, worn end-cover O-rings.
  • High oil temperature chain reaction: Severe motor internal leakage generates heat, which in turn accelerates wear.
Repair & Purchasing Recommendations
  • Light wear: Replace the oil seal + seal kit and clean the interior.
  • Severe scoring (cylinder block, valve plate, piston): Replace the rotating group parts or the complete motor assembly.
  • After reassembly, always fill the pump/motor with hydraulic oil before starting; running it dry will burn out the motor.
  • When ordering, confirm the specific D65 sub-model (-12 / -15 / -16) and the original old part number, as part numbers differ by generation.
