Description
Overview:
This non-genuine head gasket is a precision replacement for Yanmar L-series single‐cylinder diesel engines, including the L90AE and L100. It sits between the cylinder head and engine block to seal the combustion chamber and fluid passages, maintaining compression while preventing oil, coolant, and gas leakage. Made from durable, heat‐ and pressure‐resistant gasket material, it is engineered for dependable sealing in demanding site and garden machinery. The gasket measures 87.5 mm inner diameter and 100 mm outer diameter, matching the original layout for correct alignment of bores and ports. A cost‐effective alternative to the OEM part, it supports reliable running after routine service or top‐end repairs on equipment powered by these engines. Non‐genuine replacement for OEM 114970-01340. MPN: 320 100.
