Product Description
Komatsu Mining Excavator PC3000-6 PC4000-6 Fan Pump Auxiliary Hydraulic Pump
Part Numbers: 708-2G-00020, 708-2G-00021
Common Failures
  • 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, insufficient fan drive pressure and low cooling fan speed.
  • Unstable fan speed & poor heat dissipation: 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 mining excavator model PC3000-6 / PC4000-6 before placing order. The auxiliary fan pump cannot be interchanged with main hydraulic pump.
  • 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, noise and fan speed regulation function.
  • Storage requirement: Store in dry and shaded area, seal oil ports against dust and moisture.
