Yanmar 119125-01330 Cylinder Head Gasket

The Yanmar 119125-01330 cylinder head gasket is engineered for the 3TNM68 engine series, a 3-cylinder 0.784 liter water-cooled diesel power unit. This gasket provides critical sealing between the cylinder head and block, containing combustion pressure, engine coolant, and lubricating oil passages. Constructed from multi-layer steel (MLS) with elastomer coating, the gasket maintains dimensional stability across thermal cycles and resists creep relaxation. The design matches OEM fire-ring geometry and fluid port alignment for direct replacement without modification. Compatible with Yanmar 3TNM68 sub-variants including HA, HAC, HACP, HAP, HAS, HASC, HASCP, HASP, HDW, HGB2B, and HGE series engines used in compact excavators, rice transplanters, generators, and utility tractors.
