FAQ

Q1: How do I confirm this plunger fits my injection pump?

A: Check your existing plunger for the part number stamped on the barrel or packaging. Match it against 134101-6420, 9411610328, or P49. If you cannot locate the number, provide us with your engine model, pump make, and pump model number — our technical team will verify compatibility within 24 hours.

Q2: What is the correct installation procedure for this plunger and barrel?

A: Installation should be performed by a qualified diesel fuel injection technician in a clean environment. Key steps include: (1) Thoroughly clean the pump housing and all components; (2) Lubricate the plunger with clean diesel fuel or calibration oil before insertion; (3) Never force the plunger into the barrel — it should slide smoothly by hand; (4) Ensure correct orientation and alignment with the control sleeve; (5) Torque all retaining components to OEM specifications. Incorrect installation can cause immediate damage and void warranty.

Q3: How should I maintain this component for maximum service life?

A: To maximize lifespan: (1) Use clean, high-quality diesel fuel and replace fuel filters at recommended intervals; (2) Avoid water contamination in the fuel system; (3) Periodically check injection timing and pump calibration; (4) Store spare plungers in clean, dry conditions with protective oil coating; (5) Replace the plunger and barrel as a matched set — never mix components from different sets, as they are precision-lapped pairs.
