FAQ

Q1: How do I verify if this pump fits my specific Cummins NT855 engine?

A: Please check the engine serial number (ESN) located on the engine data plate. This pump is designed for the NT855 family, but minor variations in fuel system configurations exist. Cross-reference your existing pump’s part number with 4951350 or 3419493. We recommend consulting your equipment’s service manual for exact fitment.

Q2: What is the recommended procedure for installing this fuel injection pump?

A: Installation should be performed by a qualified diesel technician. Key steps include: 1) Disconnect the battery and relieve fuel system pressure. 2) Ensure the engine is at top dead center (TDC) on cylinder #1 for timing. 3) Align the pump drive gear with the timing marks. 4) Torque mounting bolts to manufacturer specifications. 5) After installation, prime the fuel system and check for leaks. Proper timing is critical for engine performance.

Q3: What maintenance is required for this fuel injection pump?

A: Regular maintenance includes: 1) Changing the fuel filters every 250 hours or as recommended by the engine manufacturer. 2) Using clean, high-quality diesel fuel to prevent internal wear. 3) Inspecting fuel lines for air leaks or restrictions. 4) Having the pump’s timing and calibration checked every 2000 hours of operation. Proactive maintenance extends the pump’s service life significantly.
