FAQ

Q: How can I confirm this rotor head fits my injection pump?
A: Please check the existing part number on your current rotor head. If it matches 146401-0520 or 9461612068, this part is a direct replacement. You can also verify by confirming your engine model is a Nissan TD27 or AD23.

Q: What is the “4/10R” designation in the product name?
A: The “4/10R” refers to the specific design and plunger configuration of the rotor head within the injection pump. It indicates the number of plungers and the rotation direction, which is critical for correct fuel distribution and timing. This is a standard spec for these Nissan applications.

Q: What is the recommended procedure for installing a new rotor head?
A: Installation should be performed by a qualified diesel mechanic. The process involves disassembling the injection pump, removing the old rotor head, cleaning the housing, and installing the new one with proper torque specifications. It is crucial to ensure the pump is correctly timed after replacement to avoid engine damage. We recommend consulting the service manual for your specific injection pump model.
