SHIM ZINC PLATED PER ASTM B633 (JLG JL91031236)

A shim that is zinc plated per ASTM B633 serves as an aftermarket replacement part, cross-referenced to JLG part number JL91031236. Its plain mechanical function is to fill small gaps between mating surfaces, ensuring proper alignment and load distribution. A worn or missing shim can lead to accelerated wear on adjacent components due to uneven contact. During assembly, a shim of incorrect thickness may cause misalignment, resulting in premature failure of the connected parts. Keeping a shim in sound condition helps maintain consistent clamping force and reduces vibration. This item ships at approximately 0.21 pounds.
