FAQ

Q1: How do I confirm which plunger size (P25, P27, etc.) fits my injection pump?
A: The plunger size is determined by the pump model and engine specifications. Check the existing plunger’s stamped code (e.g., P30) or refer to your injection pump’s service manual. If unsure, measure the plunger diameter and stroke, or contact us with your engine model and pump serial number for verification.

Q2: Can I install these plungers myself, or do I need professional service?
A: Plunger replacement requires disassembly of the injection pump and precise calibration of delivery valves. We strongly recommend installation by a certified diesel injection technician to ensure correct timing and fuel delivery. Improper installation can cause engine damage or poor performance.

Q3: What is the typical lifespan of these plungers under normal operating conditions?
A: With proper fuel filtration and clean diesel, these plungers can last 200,000 to 500,000 kilometers (or 3,000-5,000 operating hours) in heavy-duty applications. Regular maintenance, including fuel filter changes and checking for water contamination, will maximize service life. The 6-month warranty covers early failures due to material or manufacturing defects.
