FAQ

Q1: How do I confirm that this 9mm rotor head fits my injection pump?
A: Please check the existing part number on your Lucas CAV DPA pump. The rotor head must match the pump’s internal diameter. This specific unit is for 9mm applications. If your current part is 7139-130T or 7123-340T, it is a direct fit. If you are unsure, measure the diameter of your old rotor head or consult your pump’s service manual.

Q2: What is the installation procedure for this DPA rotor head?
A: Installation should be performed by a qualified diesel technician. The process involves disassembling the DPA pump head, removing the old rotor, cleaning the housing thoroughly, and installing the new rotor with proper lubrication. It is critical to maintain absolute cleanliness to prevent fuel system contamination. We recommend replacing the drive shaft seal and O-rings during service.

Q3: What is the average lifespan of this rotor head?
A: The lifespan depends on fuel quality, operating conditions, and maintenance. In standard agricultural or industrial applications with clean diesel and regular filter changes, this high-performance rotor head can last for several thousand hours of operation. The 4-month warranty covers manufacturing defects, but proper installation and fuel filtration are key to maximizing its service life.
