6275-11-3100 Replacement Common Rail Injector For Komatsu SAA4D95LE-6A

The 6275-11-3100 common rail injector assembly is a new aftermarket replacement for diesel fuel systems using the corresponding 6275-11-3100 / 295050-1090 configuration, associated with selected Komatsu SAA4D95LE-6 diesel engines. It is supplied as a replacement component only and is not a factory-branded unit.

The same fuel-system configuration lists supply pump 6275-71-1120 and common rail assembly 6275-71-1210, which are useful when identifying or repairing the complete common rail system.

Application

High-Confidence Application

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.
