FAQ

Q1: How do I confirm this head rotor fits my injection pump?
A: Verify the part number stamped on your existing rotor. This product is a direct replacement for 7139-764T and 7180-616T. It is specifically designed for DPA-type rotary fuel injection pumps. If you are unsure, please contact us with your pump model or existing part number for confirmation.

Q2: What is the typical installation process for this part?
A: Installation should be performed by a qualified diesel mechanic. It involves disassembling the injection pump, removing the old head rotor and drive shaft assembly, and carefully installing the new rotor. Proper torquing and timing are critical for correct pump operation. We recommend consulting a service manual for your specific pump model.

Q3: What maintenance is required for the new head rotor?
A: The head rotor itself is a precision component and requires no direct maintenance. However, the overall fuel injection system’s longevity depends on using clean, high-quality diesel fuel and replacing fuel filters at recommended intervals. Contaminated fuel is the primary cause of premature wear in injection pump components.
