FAQ

Q1: How do I confirm if the 7123-340U rotor head fits my injection pump?

Check your existing pump’s model number (e.g., DPA type) and rotor part number. The 7123-340U is a standard-size DPA head rotor. Measure the rotor diameter and length, and verify compatibility with your pump’s drive shaft and housing. Consult your vehicle’s service manual or contact us for technical assistance.

Q2: What is the recommended installation procedure for this head rotor?

Installation should be performed by a qualified diesel mechanic. Ensure the pump is clean and free of debris. Align the rotor’s keyway with the drive shaft, apply light lubrication, and torque to manufacturer specifications. After installation, bleed the fuel system and test for leaks. Improper installation may cause pump failure.

Q3: How can I extend the lifespan of the DPA rotor head?

Use clean, high-quality diesel fuel with proper filtration. Regularly replace fuel filters and maintain the injection pump’s lubrication system. Avoid running the engine on low fuel levels to prevent air ingress. Follow the manufacturer’s service intervals for pump inspection and replacement of wear parts.
