FAQ

Q1: Is this a matched set of plunger and barrel?
Yes, this is a precision-matched plunger and barrel assembly. They are manufactured and lapped together as a single unit to ensure the precise clearances required for high-pressure fuel injection. It is critical to replace them as a set, not individually.

Q2: How do I know if this K155 plunger will fit my injection pump?
The K155 designation refers to the plunger diameter and helix design. To confirm fitment, please check the existing part number on your current plunger. The primary cross-reference numbers are 140153-4320, 2 418 450 037, or 2450 037. If your pump uses one of these numbers, this part is the correct replacement. If you are unsure, please contact our support team with the model of your injection pump (e.g., Bosch VE, inline pump).

Q3: What maintenance is recommended before installing a new plunger and barrel?
Before installation, it is essential to thoroughly clean the fuel injection pump housing and ensure no debris or old fuel residue remains. Always lubricate the new plunger with clean diesel fuel or assembly oil during installation. It is also highly recommended to replace the delivery valve and check the condition of the pump camshaft and tappets to prevent premature wear of the new component.
