FAQ

Q1: How do I confirm this rotor head fits my injection pump?
A: Please verify your pump’s existing rotor part number (look for 9094-404S or 708S) and the rotor shaft size (3/8.5R). Measure the shaft diameter and spline configuration if possible. If you are unsure, provide us with your pump model and engine details for cross-verification.

Q2: What is the installation procedure for this DPA head rotor?
A: Installation should be performed by a qualified diesel technician. Generally, it involves removing the pump head, extracting the old rotor, cleaning the housing, and pressing in the new rotor with proper alignment. Ensure the rotor is lubricated with clean diesel fuel during assembly. Torque specifications for the retaining nut must be followed to avoid damage.

Q3: How can I maximize the lifespan of this rotor head?
A: Use clean, high-quality diesel fuel and replace fuel filters regularly. Ensure the injection pump is properly timed and calibrated after installation. Avoid running the engine with contaminated fuel or air in the system. Periodic inspection of the rotor for scoring or wear is recommended during pump servicing.
