FAQ

1. How do I confirm the correct plunger for my engine?
Check your existing plunger for the stamped part number (e.g., PT12, PT40). If the number is not visible, refer to your engine’s service manual or contact us with your engine model and injection pump details for cross-referencing.

2. What is the installation procedure for this plunger?
Installation should be performed by a qualified diesel mechanic. Ensure the fuel injection pump is clean and free of debris. Lubricate the plunger with clean diesel fuel before insertion. Follow the manufacturer’s torque specifications for the retaining screws. After installation, prime the fuel system and check for leaks.

3. How can I extend the service life of the plunger?
Use clean, high-quality diesel fuel and replace fuel filters regularly. Ensure the injection pump is properly lubricated and avoid running the engine with contaminated fuel. Periodic inspection and timely replacement of worn components will prevent damage to the plunger and pump.
