FAQ

Q1: How do I know which plunger (A765, A766, etc.) is correct for my pump?

A: You must match the plunger part number exactly to the specifications of your existing injection pump. The number is typically stamped on the pump’s data plate or on the old plunger itself. If you are unsure, please provide us with a clear photo of your old part or the pump model number for verification.

Q2: What is the recommended installation procedure for these plungers?

A: Installation should be performed by a qualified diesel technician. The plunger and barrel (if applicable) must be kept as a matched set and installed in a clean, dust-free environment. Proper lubrication with clean diesel fuel or assembly oil is essential. Ensure the plunger moves freely without binding before final assembly.

Q3: How can I extend the service life of the injection pump plungers?

A: The most critical factor is fuel quality. Always use clean, high-quality diesel fuel and replace the fuel filter at recommended intervals. Contaminants in the fuel are the primary cause of plunger wear. Regular maintenance of the entire fuel system, including the water separator, will significantly prolong the life of the injection pump components.
