FAQ

Q: Is this engine assembly a direct replacement for my existing Cummins NT855 engine?
A: This listing covers multiple models (NT855, KT19, KT38, KT50). The assembly is designed for these specific series. However, for a direct replacement, you must confirm that your engine’s model, power rating (1656 kW), and configuration match. We recommend providing your engine’s serial number for verification before purchase to ensure a perfect fit.

Q: What is the specific role of the crankshaft (part #3418898) in this assembly?
A: The crankshaft is a critical rotating component that converts the linear motion of the pistons into rotational motion to drive the propeller. Part #3418898 is a genuine Cummins specification crankshaft, designed to withstand the high torque and stress of the KT/NT series engines. It is either included as part of the assembly or is a key compatible component.

Q: What maintenance is required for this engine assembly after installation?
A: Following standard marine diesel engine practices, we recommend regular oil and filter changes, coolant checks, and valve adjustments according to the engine’s manual. Given the Euro 5 emission system, ensure that the after-treatment system (if applicable) is properly maintained. The 3000-hour warranty is contingent on following the prescribed maintenance schedule and using approved lubricants and coolants.
