FAQ

Q1: How can I confirm that part 129005-11100 is the correct valve for my 4TNV88 engine?
A: The 129005-11100 is the OEM intake valve for the Yanmar 4TNV88. To confirm, check the head of the existing valve for this stamped number. If your engine is a 4TNV88 variant (e.g., 4TNV88-BVHC), this valve should be compatible. If you are unsure, please measure the valve stem diameter and overall length to compare with our specifications.

Q2: Do you sell these valves individually, or only as a set of intake and exhaust?
A: We can supply both parts individually to meet your specific needs. Part 129005-11100 is the intake valve, and 129100-11112 is the exhaust valve. When ordering, please specify the quantity of each part number required. For a full engine overhaul, we recommend replacing all intake and exhaust valves to ensure balanced performance.

Q3: What maintenance tips can help extend the life of these new engine valves?
A: To maximize valve life, adhere to the following practices: 1) Always adjust valve clearance to the manufacturer’s specification during installation. 2) Use high-quality engine oil and change it at the recommended intervals to prevent carbon buildup on the valve stems. 3) Ensure the fuel injection system is properly timed and functioning; incomplete combustion can lead to valve burning. 4) Replace valve stem seals during installation to prevent oil from entering the combustion chamber.
