Product Description
Excavator Hydraulic Pump 708-2K-00330 708-2K-00240 708-2K-00014 Komatsu PC3000-6 PC4000-6 Main Piston Pump Pressure Pump
Common Faults & Diagnostics
  • Weak / slow movement on one pump or side: Internal leakage from worn pistons/valve plate/slippers in that section, reduced volumetric efficiency — measure each section's pressure and case drain flow to diagnose.
  • All functions weak: Insufficient main pump pressure, failed main relief valve setting, severe pump internal leakage.
  • Pump abnormal noise / squealing: Insufficient suction or air ingress (with large suction flow, cavitation damages quickly), contaminated oil, internal pump wear.
  • Engine lugging / speed drop under load: Seized power regulator/control spool; pump stays at large displacement.
  • 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 the main pump configuration (multi-section combination)
  • Confirm main pump assembly vs single pump section
  • Confirm the part number based on the original old part number; part numbers for ultra-large displacement pumps are highly specific
  • 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
