SHIM (JLG JL91121081)

A worn shim can allow unwanted movement between assembled components, leading to accelerated wear or misalignment. During assembly, a shim fills a precise gap to establish correct clearance between mating surfaces. The catalog reference for this aftermarket replacement part is JLG part number JL91121081. A shim’s condition directly affects the stability of the joint it occupies. If the gap is too large without a shim, vibration or load shift may occur. Keeping a shim of the correct thickness in place helps maintain consistent positioning. Verify the serial number or application, then call (562) 693-7748.
