FAQ

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

Match the part number on your existing plunger (e.g., A812, A814, etc.) with our listing. Measure the diameter and length to ensure standard sizing. If unsure, contact our support team with your pump model and engine serial number for verification.

Q2: Can this plunger be installed without special tools?

Installation requires basic mechanical knowledge and standard diesel injection service tools. For professional rebuilders, we recommend using a micrometer to check clearance and a torque wrench for pump reassembly. Improper installation may affect fuel timing and engine performance.

Q3: What is the expected lifespan of this plunger in heavy-duty applications?

With proper fuel filtration and maintenance, this plunger typically lasts 3,000-5,000 operating hours in industrial engines. In automotive applications, it can exceed 100,000 km. Actual lifespan depends on fuel quality, contamination levels, and operating conditions. Regular inspection is advised.
