FAQ

1. How do I confirm this plunger fits my excavator’s injection pump?

Please check the part number stamped on your existing plunger. It should match one of the numbers listed: 2418455544, 2455-544, 2455544, or 2 418 455 544. If you are unsure, contact our technical support team with your engine model and pump serial number for verification.

2. What is the recommended installation procedure for this plunger?

Installation should be performed by a qualified diesel technician. Ensure the pump housing and barrel are perfectly clean. Lubricate the plunger with clean diesel fuel or assembly oil before insertion. Use a torque wrench to tighten the retaining screws to the manufacturer’s specifications. Never force the plunger into the barrel.

3. How can I maximize the service life of this fuel injection plunger?

Use high-quality, clean diesel fuel and replace your fuel filters regularly. Contaminated fuel is the primary cause of plunger wear. Also, ensure the fuel injection pump is properly timed and the injectors are in good condition to avoid excessive pressure spikes that can damage the plunger.
