Description
Overview:
This injection washer is a solid copper sealing washer used in the fuel injection system of Yanmar L‐series single‐cylinder diesel engines, including the L40AE and L90AE. Copper is chosen for its ability to deform slightly under torque, creating a reliable crush seal that prevents fuel leaks and blow-by at high temperatures and pressures. The washer sits at a critical sealing point within the injector assembly, helping maintain correct combustion and efficient running. It is suitable for small plant and garden machinery powered by Yanmar engines, such as compactors, generators, pumps, and similar equipment. Identified by OEM reference 114350-11470, it is a direct match for the specified applications and a sensible part to replace during injector removal or routine servicing.
Key Features:
- Copper crush-type washer for a secure, leak-tight seal under heat and pressure
- Helps prevent fuel seepage and loss of compression at injector interfaces
- Stable sealing performance across repeated heat cycles in diesel engines
- Precisely sized for Yanmar L‐series injector assemblies for consistent fit
- Supports reliable starting, smoother running, and clean combustion when correctly fitted
- Simple to install during injector service, reducing downtime on site
- Corrosion resistant material suitable for diesel and common biodiesel blends
- Matches Yanmar reference number 114350-11470 for easy identification
- Suitable for construction and garden machinery powered by Yanmar L‐series engines
- Cost-effective maintenance item to replace whenever an injector is removed
Typical Applications:
Used when servicing or refitting injectors on Yanmar L‐series engines to restore a proper seal at the injector seat or mating face. Replace if there are signs of fuel staining, hard starting, rough idle, smoky exhaust, or after injector removal. Ideal for keeping compactors, generators, pumps, and small agricultural or garden machinery operating efficiently.
