FAQ

Q1: How do I verify that this plunger fits my injection pump?
A: Check the existing part number on your plunger or fuel injection pump. If it matches K329 or 134101-9120, this part is a direct fit. If unsure, consult your pump’s service manual or contact our technical support team with your pump model and serial number for assistance.

Q2: What is the recommended installation procedure for this plunger?
A: Installation should be performed by a qualified diesel technician. Ensure the pump housing and bore are clean and free of debris. Lubricate the plunger with clean diesel fuel or assembly oil before insertion. Follow the manufacturer’s torque specifications for the retaining components. After installation, prime the fuel system and check for leaks before engine start-up.

Q3: How can I extend the service life of this high-pressure plunger?
A: Use clean, high-quality diesel fuel with proper filtration. Regularly replace fuel filters as per the engine manufacturer’s schedule. Avoid running the engine with contaminated fuel or low fuel levels, which can introduce air and cause cavitation damage. Routine inspection of the injection pump for wear is also recommended.
