Product Detail
Caterpillar Fuel Injector 4P-9075 / 0R-3051
4P-9075 is a Caterpillar mechanical unit injector with cross reference 0R-3051, used on CAT 3300 Series engine applications. The unit injector combines the pump and nozzle in one body driven by the camshaft, so it is replaced as a complete assembly.

Why Unit Injectors Are Replaced
The plunger and barrel wear against each other with every camshaft revolution, and the nozzle seat erodes at the same time. As they wear, the injected quantity drifts and the engine runs rough, smokes and loses power. On these engines the injector is normally replaced as a complete unit rather than repaired in the field.
Fitting Notes
- Confirm the number on the original injector before ordering; unit injectors are matched to the engine variant.
- Renew the copper washer and O-rings and keep the injector bore clean.
- Check the rack setting and calibration after fitting where the engine requires it.
