Description
Overview:
This bonnet seal is a replacement sealing strip for Yanmar L-series single-cylinder diesel engines, matching manufacturer reference 114250-11311. Made from tough, oil- and fuel‐resistant elastomer, it sits between the engine bonnet/cover and the shroud to create a tight barrier. The seal helps prevent leaks and keeps dust and moisture out, supporting reliable running and protecting components. It also helps maintain correct cooling airflow by closing gaps around the cover. Suitable for service and repair work on compact plant powered by engines such as the Yanmar L48AE and L40AE, it is designed as a direct-fit part to restore sealing performance when the original seal has hardened, flattened, or perished through heat and vibration.
Key Features:
- Durable elastomer construction resists oil, diesel, heat, and vibration for long service life
- Accurate profile for a snug, leak-reducing seal around the engine bonnet/cover
- Helps prevent dust and water ingress to protect filters, electrics, and fuel system parts
- Supports correct cooling airflow by sealing shroud gaps, aiding stable engine temperature
- Reduces oil mist and fumes escaping at the cover joint for a cleaner engine bay
- Direct-fit replacement matching Yanmar reference 114250-11311 for straightforward compatibility
- Simple installation with basic hand tools, minimising downtime during routine servicing
- Suitable for demanding site use on compact plant and equipment

Used during servicing or rebuilds of Yanmar L-series engines in generators, water pumps, plate compactors, trench rammers, mixers, rollers, rotavators, and other small plant. Replaces worn or flattened cover seals to restore protection against contaminants and maintain stable cooling and performance.
