Description
Overview:
The Pump Shim is a thin, precision steel spacer used to set and maintain correct fuel injection pump alignment on Yanmar single-cylinder L‐series diesel engines. This non-genuine part replaces OEM No. 114250-53400 and is suitable for workshop maintenance or field repairs where accurate pump positioning is required. Fitted between the pump base and the crankcase, it helps achieve the correct pump height and timing, supporting smooth starting and reliable running. Made from durable steel with a flat, stable profile, it is designed to seat cleanly without distortion when torqued. Ideal for compact construction and garden machinery powered by these engines, including generators, water pumps, plate compactors, and small agricultural equipment. Compatible with models such as Yanmar L40 and L100.
