FAQ

Q1: How do I confirm this rotor head fits my pump?
A: Please check the number stamped on your existing pump’s rotor head or the pump housing. The primary reference numbers are 7123-340W and 7180-550W. If your pump is a Bosch CAV DPA type and uses these numbers, this part is a direct fit. If you are unsure, please provide a photo of your current part or pump tag for verification.

Q2: What is the installation procedure for this part?
A: Installation should be performed by a qualified diesel technician. The process involves disassembling the DPA pump, removing the old head rotor, and carefully installing the new unit while ensuring proper alignment and torque specifications. It is critical to maintain absolute cleanliness during installation to prevent contamination of the fuel system.

Q3: Can this part be used for repair or is it only for replacement?
A: This is a new replacement part designed to restore the pump’s performance. It is ideal for repairing a worn or failed DPA pump. Replacing the rotor head, along with other wear items like the drive shaft and vanes, can fully rebuild a pump to like-new condition.
