Frequently Asked Questions
Which Komatsu heavy mining excavators and engines use Denso injector 095000-5890?
Denso 095000-5890 is calibrated for Komatsu SAA6D114E-3 (8.27L, 6-cylinder Tier 3) industrial diesel engines. It is standard equipment on Komatsu PC300-8, PC300LC-8, PC350-8, PC350LC-8 hydraulic excavators, WA380-6 wheel loaders, and D65EX-15 / D65PX-15 bulldozers from 2006 to 2018.
What are the Komatsu OEM reference part numbers for Denso 095000-5890?
Genuine Komatsu OE numbers are 6251-11-3200, 6251-11-3201, and 6251-11-3202, with aftermarket reference DCRI105890. It belongs to the heavy-duty Denso G2 common rail architecture.
How is Denso 095000-5890 registered in the Komatsu PC300-8 engine controller?
Input the 30-digit QR compensation code stamped on the top connector into the engine controller via Komatsu K-Doc diagnostic software. This registers the manufacturing flow rate curve and prevents cylinder-to-cylinder fuel balance errors.
What is the clamp bolt tightening torque for Komatsu SAA6D114E-3 injectors?
Torque the injector hold-down clamp bolt to 34 N·m. Always clean the cylinder head bore thoroughly, seat a new 1.5 mm heat-treated copper washer, and lubricate the injector body O-ring before lowering the injector into place.
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.
