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.
