WASHER SHIM-3.06+/-.015 X-4.75 (JLG JL8307913)

A worn shim washer can cause looseness in bolted assemblies, leading to premature component wear. This aftermarket replacement part references the JLG catalog number JL8307913. The washer shim measures 3.06 inches outer diameter with a +/-0.015 tolerance and a 4.75-inch inner diameter. Its plain mechanical function is to fill gaps and distribute load between fastened surfaces. If the shim is missing or compressed beyond spec, the joint may shift under vibration, resulting in fastener fatigue or misalignment. Keeping a shim washer in sound condition helps maintain consistent clamping force in critical connections. Verify the serial number or application, then call (562) 693-7748. The item ships at approximately 0.338 pounds.
