FAQ

Q: How do I know if these valves are the correct ones for my engine?
A: The primary way to confirm fitment is to check your current valve for the stamped part number. The numbers 129900-32001 and 129900-32002 are the most reliable identifiers. You should also verify that your engine is a Yanmar 3TNE68. If you are unsure, please provide a photo of your old valve and your engine’s model plate to our support team for verification.

Q: Should I replace the valve seals and guides at the same time?
A: Yes, it is a best practice in engine rebuilding to replace the valve stem seals and inspect the valve guides whenever you replace the valves. Worn guides or seals can cause oil consumption and poor sealing, which will quickly damage new valves. We recommend ordering these supporting parts separately for a complete and reliable repair.

Q: What is the difference between part number 129900-32001 and 129900-32002?
A: 129900-32001 is typically the intake valve, which allows the air-fuel mixture into the cylinder. 129900-32002 is typically the exhaust valve, which releases the spent combustion gases. They are designed with slightly different materials and heat resistance to handle their specific roles. This listing includes both, so you have the correct valve for each position.
