FAQ

Q1: How do I verify that this K155 plunger is compatible with my fuel injection pump?
A1: Please check the model number stamped on your existing plunger or consult your pump’s service manual. The OEM numbers 140153-4320 or 1401534320 are the primary cross-references. If your pump uses an A-type element, this plunger is likely a correct fit.

Q2: What is the recommended installation procedure for this plunger?
A2: Installation should be performed by a qualified diesel technician. Ensure the pump housing and all components are thoroughly cleaned before installation. Lubricate the plunger with clean diesel fuel or assembly oil. Handle the plunger with care to avoid damaging the precision-ground surface. Torque all components to manufacturer specifications.

Q3: How can I maximize the service life of this plunger?
A3: Use high-quality, clean diesel fuel and replace your fuel filters regularly. Ensure the fuel injection pump is properly timed and calibrated. Contaminated fuel is the primary cause of plunger wear. Regular inspection and maintenance of the entire fuel system will help extend the life of this component.
