FAQ

Q1: Is this liner a direct replacement for the Cummins NH220 without modifications?
A: Yes, this liner is machined to OEM specifications. However, we recommend checking your engine block for wear or corrosion in the cylinder bore before installation. For wet-liner applications, ensure new O-rings are used.

Q2: Can this liner be used with oversized pistons?
A: This liner is designed for standard bore diameter (130.18 mm). For oversized pistons (e.g., 0.5 mm or 1.0 mm oversize), you will need a corresponding oversized liner. Contact us for availability of oversized variants.

Q3: What is the recommended installation procedure for maximum lifespan?
A: Always clean the block bore thoroughly, apply fresh coolant, and use a torque wrench to tighten cylinder head bolts to Cummins specs (typically 190–210 ft-lbs for NH220). Allow the engine to idle for 30 minutes after startup to seat the rings properly. Avoid overloading during the first 50 hours of operation.
