FAQ

Q1: How can I be sure this gasket will fit my specific Yanmar engine?
A1: This part is manufactured to the exact specifications of OEM number 119818-01330. For guaranteed fitment, please confirm your engine’s model is either a 3TNV78 or 3TN78LL. Cross-reference your old gasket’s part number or consult your engine’s service manual for verification.

Q2: What are the critical steps for installing this cylinder head gasket to ensure a proper seal?
A2: For a successful installation: 1) Ensure both the cylinder head and engine block mating surfaces are perfectly clean, flat, and free of old gasket material. 2) Do not use any sealant unless specified by the engine manufacturer. 3) Precisely follow the engine’s torque sequence and specification when tightening the cylinder head bolts to the recommended value in multiple stages. An improper torque procedure is a common cause of gasket failure.
