FAQ

Q: Is the 127510-22491 liner suitable for a standard engine overhaul or do I need oversized liners?
A: This specific part is listed as “OEM Size,” meaning it is the standard factory specification. It is intended for standard engine overhauls where the cylinder block is not excessively worn or damaged. If your block has been previously bored out, you will require an oversized liner. Always measure your block’s bore before ordering.

Q: What other parts should I replace when installing a new cylinder liner in my Yanmar 3TNM72?
A: For a successful rebuild, it is highly recommended to replace the piston, piston rings, and cylinder head gasket simultaneously. A worn piston ring set will quickly damage a new liner. We recommend sourcing a complete 3TNM72 overhaul gasket kit and piston/ring set to ensure all components wear in together perfectly.

Q: How can I confirm that this liner will fit my specific Yanmar engine?
A: The primary identifier is your engine model number, which must be 3TNM72. You should also visually compare the liner to your old part or check the number stamped on your existing liner. If your engine is a variant (e.g., 3TNM72F or 3TNM72U), the liner is likely the same, but we recommend contacting us with your engine serial number for 100% confirmation.
