Product Description
Bulldozer Komatsu D375A-6 and D375A-6R Main Control Valve Assemblies
Part Numbers: 723-66-21400, 723-66-21600, 723-65-21400
Procurement Recommendations
  • Verify OEM part number compatibility for D375A-3 models with complete blade and ripper spool sections
  • Ensure all valves (new or remanufactured) include hydraulic bench test reports covering pressure, flow, and internal leakage for each section
  • For remanufactured valves, confirm spools are either new or professionally honed and repaired, with replacement of all O-rings, relief valves, check valves, and pressure compensators
  • Inspect valve block for casting cracks upon arrival and maintain port protection to prevent contaminant entry
  • Secure valves properly during transit to prevent impact damage to ports and precision spools
  • Clean hydraulic tank and pipelines before installation, replace all hydraulic filters, and thoroughly bleed air from the circuit
  • Conduct comprehensive testing after installation including blade lift/tilt, ripper operation, cylinder drift, and system relief pressure verification
