FAQ

Q: Will this liner fit my Cummins ISM11 engine with serial number 123456?
A: The liners with part numbers 3803703, 3801254, and 3080760 are standard for ISM11 and M11 engines. However, engine updates may have occurred. We strongly recommend checking your engine serial number against Cummins documentation or contacting us with your serial number for confirmation.

Q: What is the recommended installation procedure for this cylinder liner?
A: Installation requires careful cleaning of the cylinder bore, proper application of sealant (O-rings or gaskets are included in a full kit, sold separately), and precise torquing of cylinder head bolts. We recommend using a professional mechanic familiar with Cummins engines to ensure correct protrusion height and avoid coolant leaks.

Q: How can I ensure long service life from this liner?
A: Use high-quality coolant with correct corrosion inhibitors, perform regular oil changes with the recommended viscosity, and avoid excessive engine idling. Always replace piston rings and seals when installing new liners for a complete overhaul.
