FAQ

Q: How do I know if this Plunger and Barrel Assembly is the correct part for my pump?
A: The most reliable method is to remove the old plunger and barrel from your pump and compare the physical dimensions (length, diameter, and slot configuration) with this unit. The part numbers 2 418 455 705 and 2455/705 are the primary identifiers. If in doubt, please contact our support team with a photo of your old part.

Q: What is the installation procedure for this part?
A: Installation should be performed by a qualified diesel technician. The process involves removing the delivery valve holder, extracting the old plunger and barrel, and carefully inserting the new assembly. It is critical to keep all parts scrupulously clean to avoid damage. The fuel pump must be re-calibrated on a test bench after installation to ensure correct injection timing and fuel volume.

Q: Can I replace just the plunger, or do I need to replace the barrel too?
A: This is a matched set. The plunger and barrel are lapped together to create a precise, high-pressure seal. They must always be replaced as a pair. Installing a new plunger into an old barrel (or vice versa) will result in poor performance, fuel leakage, and rapid wear.
