FAQ

Q: Is this liner a direct fit for my Yanmar 4TNE92 engine?
A: Yes, part number 729901-92660 is the OEM standard liner for the 4TNE92 engine. It is a direct drop-in replacement. Please verify your engine serial number to ensure it uses the standard bore size (92mm).

Q: What is the recommended installation procedure?
A: Installation requires proper cleaning of the cylinder block bore. The liner should be pressed in using a suitable tool and lubricated with engine oil. After installation, the liner protrusion (height above the block deck) must be checked with a dial gauge to ensure it is within the OEM specification (typically 0.02-0.10mm) to prevent head gasket failure.

Q: Does this liner come with a piston or piston rings?
A: No, this listing is for the cylinder liner only (part 729901-92660). We recommend using new piston rings and checking the piston-to-liner clearance when rebuilding the engine. Please contact us if you require a complete piston and liner kit.
