6275-11-3100 Original Fuel Injector 295050-1090 For Komatsu PC138US-10

6275-11-3100, also written without hyphens as 6275113100, is the original common rail injector assembly for selected Komatsu SAA4D95LE-6 diesel engine applications. Its widely used Den-so cross reference is 295050-1090. Komatsu identifies 6275-11-3100 as an Injector Assembly.

The confirmed application is the Komatsu PC138US-10 / PC138USLC-10 fitted with the SAA4D95LE-6A engine.

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.
