Description
Overview:
This injector washer (MPN 124550-51350) is a copper crush sealing ring for Yanmar small diesel engines, including L40AE and L48AE. It sits between the injector and the cylinder head to provide a gas- and fuel-tight seal, helping to maintain correct injection pressure and preventing combustion blow-by.

Used across a wide range of compact Yanmar engines in construction and garden machinery, it supports reliable running in equipment such as generators, compactors, pumps, and mowers. Built to meet OEM fit and performance requirements, it is a straightforward replacement during injector servicing and routine maintenance to keep fuel systems efficient and starting dependable.
