Description
Overview:
This non-genuine Rocker Cover Gasket is an aftermarket replacement for Yanmar diesel engines, made to seal the rocker (valve) cover to the cylinder head and prevent oil leaks. Manufactured from durable, oil-resistant gasket material, it maintains a clean, tight seal under heat and vibration, helping to protect the valvetrain area from dust and debris. It is a direct replacement for engines such as the Yanmar L90 and L100 found on compactors, generators, pumps, mixers, and other site and garden machinery. The gasket is shaped for an accurate fit to the cover profile and is suitable for routine servicing or repairs where the original gasket has become hard, flattened, or damaged, helping to restore reliable engine operation without modification.

- Non-genuine replacement compatible with OEM reference 114650-11310

- Straightforward installation using standard hand tools; no machining or alterations required
