Product Description
Komatsu Articulated Dump Truck HM400-3 HM400-5 Hydraulic Pump
Piston Pump, Main Hydraulic Pump 708-2W-00450 708-1W-02260 708-1W-02270
Common Fault Symptoms
  • Abnormal pump noise: Worn pistons and slippers, scratched valve plate; air ingress in suction line, contaminated hydraulic oil
  • Insufficient output pressure: Internal leakage caused by worn piston pairs and aged seals; faulty pressure regulator, pressure fails to reach rated value
  • Slow lifting & tilting movement: Reduced volumetric efficiency of hydraulic pump and insufficient output flow; clogged suction filter element, excessive suction resistance
  • Excessively high hydraulic oil temperature: Severe internal leakage inside pump and increased frictional heat; incorrect hydraulic oil grade or deteriorated oil
  • Pump housing leakage: Aged and damaged end cover seals and O-rings; uneven tightening torque of bolts, cracked housing
Purchasing Recommendations
  • Verify the stamped part number on old pump and truck model HM400-3 / HM400-5 before placing order. Hoist piston pump and steering gear pump have different structures, similar part numbers cannot be directly interchanged.
  • New assembly or remanufactured assembly are available. For reman pumps, confirm factory test report and warranty period.
  • Replace full seal kit during installation, inspect hydraulic oil and suction filter to avoid premature wear and damage of new pump.
  • Inspection upon arrival: Check pump housing for dents and cracks, intact oil port threads and legible nameplate. Perform no-load test before installation to check pressure and noise.
  • Storage requirement: Store in dry and shaded area, seal oil ports against dust and moisture.
