FAQ

Q1: Is this cylinder liner a direct fit for my Yanmar 4TNV84 engine?
A: Yes, this liner is a direct, drop-in replacement for the standard bore 84mm Yanmar 4TNV84 and 4TNE84 engine families. It matches the OEM specifications of part numbers 129105-22900 and 129350-01100. We recommend cross-referencing your engine’s serial number to confirm compatibility.

Q2: Do I need to replace the piston rings and gaskets when installing this liner?
A: Yes, it is highly recommended to replace the piston rings, cylinder head gasket, and all related seals when installing a new cylinder liner. This ensures a proper seal, prevents leaks, and maximizes the lifespan of the new component. We offer complete overhaul gasket kits for these engine models.

Q3: How do I properly install this dry cylinder liner?
A: Installation requires careful preparation. The engine block bore must be thoroughly cleaned and checked for burrs. The liner should be installed using a specialized press tool with even pressure, or by using the freezer method for a light interference fit. Never hammer the liner directly. Always check the liner protrusion height above the block deck after installation to ensure it is within the manufacturer’s specified range (typically 0.00-0.10mm).
