Komatsu PC600/650-8 Excavator Main Control Valve
Part Number: 709-99-15100
Procurement Recommendations
  • Verify OEM part number and confirm valve assembly compatibility with complete boom, arm, bucket, and travel spool sections
  • Ensure new or remanufactured valves include hydraulic bench test reports covering pressure, flow, and internal leakage for each section
  • For remanufactured valves, confirm spools are new or honed and repaired, with replacement of all O-rings, relief valves, check valves, pressure compensators, and LS shuttle valves
  • Inspect valve block for cracks upon arrival and protect oil ports to prevent dirt contamination
  • Secure the valve during transportation to avoid impact damage to ports and precision spools
  • Clean hydraulic tank and pipelines before installation, replace all hydraulic filters, and bleed air from the system
  • Test boom, arm, bucket, travel movement, cylinder drift, and system relief pressure after installation
Common Faults & Solutions
Spool & Valve Bore Wear, Excessive Internal Leakage
Symptoms: Weak digging power; performance worsens when hot; cylinder drift and high oil temperature
Cause: Contaminated oil scratches spool and bore, increases clearance
Stuck Spool, Slow or Jerky Action
Symptoms: Stiff control lever, delayed movements; no operation if spool stuck at neutral
Cause: Dirt, oil sludge, deformed or broken return spring
Main Relief Valve / Pressure Compensator Failure
Symptoms: Low working pressure, pressure fluctuation, whistling noise, poor combined action
Cause: Worn valve parts, fatigued spring, clogged orifice
Damaged O-rings, External Oil Leakage
Symptoms: Oil seepage between valve slices and end caps
Cause: Loose bolts and aged seals, air ingress triggers cavitation
Clogged LS Shuttle Valve and Orifice
Symptoms: Abnormal LS signal pressure, poor pump-valve matching, overheating and high fuel consumption
Cause: Fine contaminants block load-sensing passages
Holding Valve Seal Failure, Cylinder Drift
Symptoms: Boom/arm sinks slowly, worse under heavy load
Cause: Dirt or wear on sealing surface of holding valve
Valve Block Cracking (Rare but Serious)
Symptoms: Sudden heavy oil leakage, unable to build pressure
Cause: Pressure shock, uneven bolt torque, casting defects
