FAQ

Q1: How can I be sure this valve seat will fit my Yanmar 3TNV80 engine?
A1: This part is manufactured to the exact OEM size and specifications for the Yanmar 3TNV80 engine. For absolute certainty, we recommend providing the existing part number from your engine or consulting your engine’s service manual. Our technical team can also assist with cross-referencing.

Q2: What is required for the proper installation of this valve seat?
A2: Professional installation is strongly recommended. The process typically involves heating the cylinder head (using an oven or induction heater) to expand the metal, then chilling the valve seat to contract it (using liquid nitrogen or dry ice) for a precise interference fit (“shrink-fit”). Proper machining of the seat pocket in the cylinder head is also critical.
