Description
Overview:
The Gasket, Bonnet is a Genuine Yanmar part for small air‐cooled diesel engines, including the L90AE and L100AE. Supplied under MPN 114650-11311, it is made from durable, heat- and oil‐resistant gasket material designed for engine environments. Its job is to seal the bonnet/cover to the engine housing, helping to prevent oil and air leaks and to keep contaminants out of the engine. A correct seal supports stable running, reduces mess from weeping joints, and protects internal components. This gasket is a direct replacement to restore factory sealing after inspection, repair, or routine servicing of the cover area. It suits tradespeople maintaining site equipment as well as DIY users keeping generators, pumps, and compact plant powered by Yanmar L‐series engines in good order.
Key Features:
- Genuine Yanmar part for assured fit and specification (MPN 114650-11311)
- Durable gasket material engineered for heat, vibration, and oil exposure
- Accurate profile for the bonnet/cover interface to minimise leaks and misting
- Helps protect internal components by maintaining a clean, sealed joint
- Consistent sealing performance supports engine reliability over time
- Suitable for routine maintenance, rebuilds, and leak rectification
- Simple, like‐for‐like replacement with no modification required when used with the correct model
- Designed to fit within OEM tolerances for ease of installation
Typical Applications:
Used when refitting the cover/bonnet after inspection or service, or when curing oil seepage from the joint. Common during routine maintenance, engine overhauls, or component replacement on equipment powered by Yanmar L‐series engines such as generators, water pumps, light construction machinery, and compact agricultural or garden machinery.
