FAQ

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

A: Please verify the OEM number on your original plunger. This part is identified by numbers A829, 131150-2620, or 1311502620. If your part matches any of these numbers, it is the correct replacement. For further verification, consult your fuel injection pump’s service manual.

Q: What is the installation procedure for this high-pressure plunger?

A: Installation should be performed by a qualified diesel technician. Ensure the work area is clean. Carefully remove the old plunger and inspect the pump bore for scoring. Lubricate the new plunger with clean fuel or assembly oil before insertion. Follow the manufacturer’s torque specifications for the retaining components to avoid damage.

Q: What is the recommended maintenance for this plunger?

A: The plunger itself is a wear item. Its lifespan depends on fuel quality and operating conditions. To maximize service life, always use clean, high-quality diesel fuel and replace the fuel filter regularly. Inspect the plunger during routine injection pump maintenance. If you notice a drop in engine performance or hard starting, the plunger may need inspection.
