FAQ

Q: How do I confirm this piston will fit my specific Yanmar engine?
A: First, identify the exact model of your engine (e.g., 4TNC88). Then, locate the existing piston or your engine’s parts manual to verify the OEM part number is 129001-22081. Matching both the engine model and the part number is the most reliable method for confirming fitment.

Q: Is this piston sold as a single unit or as part of a set?
A> This piston is sold as a single item. For a complete engine overhaul, you will need to purchase one piston per cylinder. We recommend inspecting and replacing all pistons in an engine simultaneously for balanced performance.

Q: What documentation is provided with the part for international buyers?
A> We provide full export documentation, including a commercial invoice and packing list. Upon request, we can also supply machinery test reports and video outgoing-inspection records to support quality claims and facilitate customs clearance in your country.
