FAQ

Q1: How do I confirm this head rotor fits my pump?
A: Please check the part number on your existing pump head rotor. The primary numbers are 9003-135U or 9003-135L. Also, verify your pump is a DPA (Distributor Pump) type with a 6/9R specification. If your rotor number is 615U, this part is the correct replacement.

Q2: What is the recommended installation procedure?
A: Installation should be performed by a qualified diesel injection technician. The process involves careful disassembly of the pump head, cleaning of the housing, precise alignment of the new rotor, and reassembly with new seals. Proper torque specifications and cleanliness are critical to prevent contamination and ensure correct pump timing.

Q3: What maintenance is required after installing a new head rotor?
A: After installation, it is essential to prime the fuel system to remove air. The injection pump should be re-calibrated on a test bench to ensure correct fuel delivery and timing settings. Regularly check for fuel leaks and ensure the fuel filter is changed according to the vehicle’s service schedule to protect the new rotor from contaminants.
