Description
Overview:
The thrust washer is a precision steel spacer used in Robin/Subaru DY23 and DY27 diesel engines to control axial movement and minimise friction between rotating faces. Fitted at key bearing locations, it maintains correct end float so the crankshaft and related components run smoothly under load. By keeping contact surfaces properly separated and supported, it helps protect the crankcase and bearings from wear, improving engine reliability over long service intervals. This washer is suitable for a wide range of compact construction and garden machinery powered by DY-series engines, such as plate compactors, generators, pumps, and mixers. Supplied to match the original specification and dimensions for a straightforward replacement, it aligns with OEM reference 243-25003-03 for assured compatibility during routine maintenance or full rebuilds.
Key Features:
- Steel construction for dependable wear resistance under continuous load
- Controls axial end float to protect crankcase and bearing faces
- Reduces friction between mating components for smoother running
- Matches OEM specification for correct fit and alignment
- Suitable for both DY23 and DY27 engines for simplified stocking
- Consistent thickness and flatness for stable, repeatable performance
- Straightforward to install during servicing or rebuilds; typically no special tools
- Helps extend service life of associated bearings and rotating assemblies
Typical Applications:
Used during engine servicing and rebuilds on DY-series equipment to restore correct end float and reduce wear. Common in light plant and garden machinery such as plate compactors, generators, water pumps, mixers, power trowels, and small chippers that rely on Robin/Subaru DY23 or DY27 engines. Ideal when addressing axial play, clutch or flywheel work, or preventive maintenance schedules.
