FAQ

Q1: How do I confirm this rotor head fits my DPA pump?
A: Verify the part number on your existing pump head. This rotor is for standard DPA pumps using numbers 7123-909T or 7180-571T. Physically measure the rotor diameter and shaft length. For 4-cylinder applications, this is the standard size. If your pump uses a different number (e.g., 7135-xxx), please contact us for cross-reference confirmation.

Q2: Can I replace just the rotor head without overhauling the entire pump?
A: Yes, this is a common repair for worn rotor heads. However, we recommend inspecting the pump housing, drive shaft, and delivery valves for wear. If the pump has high mileage or contamination, a full pump rebuild kit is advisable to ensure longevity. Our rotor head is a direct replacement for the worn unit.

Q3: What maintenance is required after installation?
A: After replacing the rotor head, the injection pump must be re-timed to the engine using a timing light or dial gauge per the engine manufacturer’s specifications. Prime the fuel system to remove air. Check for leaks at high idle. We recommend an initial service check after 50 hours of operation to re-torque the pump mounting bolts.
