FAQ

1. Is this cylinder head assembly a direct bolt-on replacement for my Yanmar 3TNV80 engine?

Yes, this is a complete assembly designed as a direct replacement. It includes all necessary components (valves, springs, seals, and retainers) pre-installed. However, we strongly recommend using a new cylinder head gasket set and tightening head bolts to the manufacturer’s specified torque sequence and angle (typically 40 Nm + 90° turn). Always confirm your engine’s serial number against the 119717-11740 part number.

2. What is the typical installation time for this cylinder head?

For a qualified diesel mechanic, replacing a cylinder head on a 3TNV80 engine typically takes 4-6 hours. This includes draining fluids, removing the old head, cleaning the block surface, installing the new head with a fresh gasket, and reassembling the valve train and cooling system. We recommend replacing the head bolts and coolant simultaneously during this service.

3. Can I use this cylinder head on a Yanmar 3TNV76 or 3TNV82 engine?

No. This specific assembly (119717-11740) is designed exclusively for the 3TNV80 engine with an 80mm bore. The 3TNV76 and 3TNV82 engines have different bore sizes and combustion chamber designs. Using an incorrect cylinder head will result in poor compression, potential piston-to-valve contact, and engine damage. Please verify your engine model is 3TNV80 before purchasing.
