Fitment Notice

Please verify your pump before ordering.

The most reliable way to confirm this part is by checking your pump model number, your old part number, or a parts breakdown for your specific injection pump.

Many tractors and engines used more than one injection pump depending on year, serial number, engine build, market, or previous replacement history. If your pump has been changed in the past, the correct internal parts may not match the original equipment listing.

Repair Disclaimer

Diesel injection pumps are precision fuel system components. Internal pump parts should be installed in a clean environment by someone familiar with pump disassembly, inspection, timing, and reassembly.

This part is sold as a replacement repair part only. It does not include rebuild instructions, calibration service, or technical repair support.

If you are not experienced with diesel injection pump repair, we recommend having the pump serviced by a qualified diesel injection shop.
