FAQ

Q: Is this liner a direct fit for my 6D40 engine, or will I need modifications?

A: This liner is a direct OEM replacement. No modifications are required. Ensure you are replacing a standard bore liner (130mm). If your block has been overbored, you will require a +0.50 or +1.00 oversized liner.

Q: Should I replace piston rings when installing a new cylinder liner?

A: Yes, it is strongly recommended to install new piston rings with a new cylinder liner. Used rings will not seat properly against the new honed surface, leading to blow-by and reduced compression. We recommend replacing the piston ring set (Part No. ME120029) simultaneously.

Q: What is the recommended installation procedure for this wet liner?

A: Clean the liner bore and block counterbore thoroughly. Apply a light coating of clean engine oil to the O-rings and the liner outer surface. Using a liner press tool, gently press the liner into place. Do not hammer. After installation, perform a protrusion check; the liner top should sit 0.01-0.05mm above the block deck surface for proper cylinder head gasket sealing.
