Frequently Asked Questions
What Komatsu construction excavators and engines use Denso injector 095000-6310?
Denso 095000-6310 is calibrated for Komatsu SAA6D107E-1 (6.7L, 6-cylinder) turbocharged common rail engines. It is standard equipment on Komatsu PC200-8, PC200LC-8, PC220-8, PC220LC-8, PC240LC-8 excavators, WA200-6 and WA250-6 wheel loaders, and D39EX-22 bulldozers from 2006 to 2017.
What are the Komatsu OEM cross-reference part numbers for Denso 095000-6310?
The genuine Komatsu part numbers are 6271-11-3100 and superseded number 6271-11-3101, corresponding to Denso revisions 095000-6311 and 095000-6312. These part numbers share the DLLA152P879 nozzle specification.
How is the Denso 095000-6310 coded into the Komatsu engine controller?
Input the 30-digit alpha-numeric QR compensation data stamped on the injector connector into the engine controller using the Komatsu Diagnostic Tool (K-Doc). This aligns high-pressure injection timing maps and ensures smooth fuel metering across 1,600 bar operating pressure.
What tightening torque is required for Komatsu PC200-8 injector hold-down bolts?
Torque the injector clamp mounting bolt to 34 N·m. Ensure the nozzle projection protrusion through the cylinder head matches factory spec (1.6 to 1.8 mm) using the standard 1.5 mm copper washer.
Diagnostic Trouble Codes & Fault Protocols
Common diagnostic trouble codes (DTCs) triggered when this common rail injector experiences wear, circuit faults, or calibration drift:
Fuel Rail / System Pressure Too Low
Excessive internal backleak from worn control valve seats drops common rail pressure below target under engine load.
Injector Circuit Malfunction / Open Circuit
Solenoid coil resistance drift (0.2-0.5 Ω) or piezo stack degradation triggers driver stage shutdown on affected cylinders.
Cylinder Misfire & Balancing Deviation
Carbon-clogged nozzle spray holes or missing IMA calibration causes uneven cylinder contribution. Recode ECM and verify washer seating.
Fuel Rail / System Pressure Too High
Spill line backpressure or stuck metering valve prevents rail depressurization, creating overpressure risks under load.
