FAQ

Q: How do I confirm this liner fits my Yanmar 4TNV106 engine?
A: First, locate the part number on your existing liner or your engine’s parts manual. The primary numbers are 129901-01198 and 123950-01100. If your engine is a 4TNV106, 4TNE106, or 4D106, this is the correct standard-size liner. We recommend measuring the cylinder bore in your block to confirm it is within service limits for a standard liner.

Q: What is the difference between a dry liner and a wet liner? Is this one?
A: This specific part is designed as per the Yanmar OEM specification for the 4TNV/4TNE/4D series. Typically, these engines use a dry liner design, which means the liner is pressed into the block and does not come into direct contact with the engine coolant. This design provides a rigid cylinder wall. For definitive identification, check your service manual.

Q: What maintenance is required when installing a new cylinder liner?
A: Proper installation is critical. The cylinder bore in the block must be clean and free of burrs. The liner should be installed using a proper driver tool to avoid distortion. After installation, the liner height (protrusion) above the block deck must be checked with a dial gauge to ensure it is within spec for proper head gasket sealing. We recommend replacing piston rings and cylinder head gaskets simultaneously for a complete and reliable rebuild.
