FAQ

Q: How do I confirm this liner (129930-01100) fits my engine?
A: To confirm fitment, please check the engine model plate on your equipment. This liner is specifically designed for the Yanmar 4TNE94 and 4TNV94 diesel engines. It is a standard OEM-size liner. If your engine block has already been bored to a specific oversize, you will require a corresponding oversized liner, not this standard part. Always cross-reference your existing part number with 129930-01100.

Q: What is the recommended installation procedure for this cylinder liner?
A: Installation should be performed by a qualified diesel mechanic. Key steps include: 1) Thoroughly cleaning the cylinder block bore. 2) Applying a suitable sealant (e.g., Loctite) to the outer surface of the liner’s lower flange. 3) Using a specialized liner press tool to gently press the liner into the block until it is fully seated. 4) Measuring the liner protrusion above the block deck to ensure it is within the engine manufacturer’s specified tolerance (typically 0.02-0.12mm). 5) Honing the liner bore to the final cross-hatch pattern if required for new piston rings.

Q: What maintenance should I perform after installing a new cylinder liner?
A: After installation, it is critical to follow a proper break-in procedure. This involves running the engine at varying speeds and loads for the first 10-20 hours, avoiding prolonged idling or full-throttle operation. Use high-quality engine oil and a new oil filter. After the break-in period, perform an oil change to remove any initial wear particles. Regularly check the coolant level and condition to prevent corrosion of the liner’s outer surface. Adhering to the manufacturer’s service intervals for oil and filter changes will maximize the lifespan of the new liner and piston rings.
