FAQ

Q: Is this piston a direct fit for my Yanmar 3TNM74 engine, or do I need other parts?
A: This piston (119D00-22080) is a direct-fit replacement for the Yanmar 3TNM74 engine. However, during an engine overhaul, it is highly recommended to also replace the piston rings, cylinder liners, and connecting rod bearings to ensure optimal performance and sealing. Please verify your engine’s serial number to confirm the piston size is correct.

Q: What is the installation procedure for this piston?
A: Installation should be performed by a qualified diesel mechanic. Key steps include: thoroughly cleaning the cylinder bore, lubricating the piston and rings with engine oil, using a proper ring compressor to install the piston into the cylinder, and torquing the connecting rod bolts to the manufacturer’s specified settings. Never reuse old circlips or bolts.

Q: How can I verify the quality of the piston before installation?
A: We provide a machinery test report and offer a video outgoing inspection service upon request. You can also visually inspect the piston for any casting defects or damage. Measuring the piston diameter with a micrometer and comparing it to your cylinder bore clearance specifications is a standard best practice before final assembly.
