WASHER SHIM .265 X .5 X .030 (Doosan DWMF450004)

A worn shim washer can cause looseness in bolted assemblies, leading to premature component wear. This aftermarket replacement part references the Doosan catalog and cross-references part number DWMF450004. The washer shim measures .265 inch inside diameter by .5 inch outside diameter by .030 inch thickness. Its plain mechanical function is to provide a precise spacing layer between a fastener head and the mating surface. A common failure consequence is that a missing or compressed shim allows fastener torque to relax, resulting in vibration and eventual joint failure. This type of shim is often used during assembly adjustments to achieve correct clearance or preload. Verify the serial number or application, then call (562) 693-7748.
