6275-11-3100 Remanufactured Common Rail Injector For Komatsu PC138US-10 Engine

Product Specification

6275-11-3100 Remanufactured Common Rail Injector For Komatsu PC138US-10

This is a remanufactured common rail injector assembly for applications identified by Komatsu 6275-11-3100 (also written 6275113100) and the fuel-system reference 295050-1090, used with selected Komatsu SAA4D95LE-6 diesel engines. It is a remanufactured unit, not a new factory injector.

Each core is fully disassembled, cleaned and inspected, then rebuilt with new wear parts and 100% tested before packing.

SAA4D95LE-6 Injector Assembly Parts

Engine parts documentation for the SAA4D95LE-6 configuration lists the following items together in the injector assembly section.

Complete Fuel-System References

The same SAA4D95LE-6 / PC138US-10 documentation lists the surrounding fuel-system assemblies.

Repair Nozzle

Repair-market nozzle reference: G3S59 (repair-market reference only; not stated as an official Den-so nozzle without further confirmation).

Remanufacturing Process

• Full disassembly of the returned core
• Cleaning, inspection and rebuild with new wear parts
• Cross reference 295050-1090
• SAA4D95LE-6A / PC138US-10 application
• Four-piece engine set or individual injector supply
• Repair-market nozzle reference G3S59
• 100% bench tested before packing
• Neutral or customized export packing

Application

High-Confidence Application

Komatsu documentation confirms PC138US-10 uses the SAA4D95LE-6 common rail engine, while engine-parts references identify the -6A parts book for PC138US-10 / PC138USLC-10.

About 6275-11-3101

6275-11-3101 is listed as an Additional / Service Reference only. Komatsu catalogues separately list a 6275-11-3101 Injector Assembly and repair channels often pair 3100 / 3101, but no official supersession table confirming a complete replacement in all applications has been verified, so it is not stated as a direct supersession of 6275-11-3100.

Correct Part Identification

Please confirm the following before ordering:

1. Komatsu OE number: 6275-11-3100
2. Injector reference: 295050-1090
3. Engine model: SAA4D95LE-6A or complete engine identification
4. Machine model and serial number
5. Clear photo of the injector label

Machine model alone should not be used as the final identification method because different SAA4D95LE engine variants may use different fuel-system specifications.

Komatsu SAA4D95LE Engine Variant Note

This page locks only the confirmed configuration: 6275-11-3100 / 295050-1090 → Komatsu SAA4D95LE-6A → PC138US-10 / PC138USLC-10. Other SAA4D95LE-6 variants may use different calibrations — for example PC78US-10 is documented with the SAA4D95LE-6E suffix, and market listings also extend this injector to PC120-10, PC120-11 and PC128US-10 without an equivalent OEM application table. Do not assume all 4D95 engines use the same injector. Other Komatsu injectors, pumps and rail components are treated as related products only; they are not mandatory matched parts for 6275-11-3100. Always confirm by the number stamped on the existing injector, the engine variant and the machine serial.

Related Fuel System Parts

6275-71-1120 fuel supply pump assembly and 6275-71-1210 common rail assembly are listed together with 6275-11-3100 under the SAA4D95LE-6 / PC138US-10 documentation. These are related references for the same fuel-system configuration; they are not mandatory matched parts.
