FAQ

Q1: How do I confirm this valve fits my specific Yanmar engine?
A: First, locate the engine model plate on your equipment. It should clearly state “3TNV80”. If your engine is a different model (e.g., 3TNV82 or 4TNV80), this valve will not fit. We also recommend comparing the physical dimensions (valve head diameter and stem length) with your old part to ensure a perfect match.

Q2: Is this a complete set for a 3TNV80 engine, or a single valve?
A: The product is sold as a set of valves required for the 3TNV80 engine. A 3-cylinder engine typically requires 6 valves (3 intake and 3 exhaust). Please check the product listing for the exact quantity. If you need individual valves or specific intake/exhaust types, please contact our support team for a custom order.

Q3: What maintenance should be performed when replacing these valves?
A: When replacing engine valves, it is strongly recommended to also replace the valve stem seals and check the condition of the valve guides. After installation, the valve clearance must be adjusted according to the Yanmar 3TNV80 service manual specifications to ensure proper engine operation and prevent premature wear. We recommend having this work performed by a qualified diesel mechanic.
