Machine ModelPart Number
CAT 31261807341

The 1807341 unit injector pump cat 3126 provides precise, high-pressure fuel atomisation into the combustion chamber of the CAT 3126 engine, ensuring complete combustion, full power output, and minimal emissions. A failing injector delivers incorrect fuel quantities and spray patterns, causing rough running, power deficiency, increased fuel burn, and the risk of carbon build-up in the combustion chamber. Built to OEM specification 1807341 for direct fitment on the CAT 3126, restoring complete combustion efficiency from installation.

Key Features:

  • High-Pressure Injection Accuracy: Provides accurate fuel delivery timing and volume for full power and efficient combustion.
  • Direct OEM Replacement: Built to specification 1807341 for exact fitment on the CAT 3126.
  • Combustion Restoration: Eliminates rough running, power loss, and excessive smoke caused by a worn or clogged injector.

The 1807341 unit injector pump cat 3126 is an essential fuel injection component for maintaining power output and fuel economy on the CAT 3126.

What Does This Injector / Fuel Pump Assembly Do?

Delivers a precisely metered, high-pressure fuel spray directly into the combustion chamber at the timing commanded by the ECU. Correct injector operation is critical for power output, fuel efficiency, and meeting emissions requirements.
