SHIM (Mitsubishi MB1009617)

MB1009617: A shim that is too thin or missing can allow excessive clearance, leading to premature wear of adjacent components. This aftermarket replacement part references Mitsubishi as the OE maker and cross-references part number MB1009617. A shim is a thin, flat component used to fill small gaps or adjust the alignment between two mating surfaces. Its plain mechanical function is to occupy space and establish a precise fit between parts. When a shim fails or is omitted, the resulting looseness can cause vibration, noise, or accelerated component fatigue. Keeping a shim in sound condition helps maintain proper spacing and load distribution in the assembly. Verify the serial number or application, then call (562) 693-7748.
