Description
Excavator Hydraulic Pump 95601040 95784040 96326540 Komatsu PC4000-6 PC8000-6 Main Piston Pump Pressure Pump
The PC4000/8000-6 is a Komatsu ultra-large mining hydraulic shovel. The machine uses multiple large-displacement variable displacement piston pumps supplying oil in parallel for working, rotating and other circuits, plus a pilot pump. 95601040 is one of the main pump part numbers for this model. These pumps have enormous displacement, very high power and very high unit price, making them the most critical high-value component of the machine.
Common Faults
  • Weak / slow movement on one pump or circuit: Internal leakage from worn pistons/valve plate/slippers in that pump section, reduced volumetric efficiency — measure each pump's pressure and case drain flow to diagnose.
  • All functions or a specific action weak: Insufficient main pump pressure, failed main relief valve setting, severe pump internal leakage.
  • Pump abnormal noise / squealing: Insufficient suction or air ingress (large suction flow accelerates cavitation damage), contaminated oil, internal pump wear.
  • Engine lugging / speed drop under load: Seized power regulator/control spool; pump stays at large displacement and absorbs excessive power.
  • High oil temperature: Severe main pump internal leakage, high-pressure oil converting to heat.
  • Oil leakage: Aged main shaft oil seal, worn end-cover O-rings, poor case drain.
  • Jitter / pressure fluctuation: Air in the system, seized regulator, scored valve plate.
Purchasing Recommendations
  • Confirm the sub-model and pump configuration (multi-pump combination, working/rotating section split)
  • Confirm main pump assembly vs single pump / single section
  • Confirm the full configuration of part No. (displacement, interface, cross-check against original old part number)
  • Confirm condition: genuine new units are extremely expensive; remanufactured (Reman) units are the mainstream cost-saving option; aftermarket compatible units require extreme caution
  • Overhaul parts: cylinder block, valve plate, piston (slipper), retainer plate, swashplate, main shaft, bearings, seal kit
  • After-sales: warranty; fill with hydraulic oil before starting; after repair, replace all filters and clean the oil tank; for ultra-large pumps, prefer genuine or specialized-factory remanufacturing
