SHIM (Genie GN639291)

GN639291: A worn shim can cause excessive play and misalignment in the assembly it supports. The Genie catalog reference for this aftermarket replacement part is GN639291. A shim is a thin, flat component used to fill small gaps or adjust the fit between two mating surfaces. Its plain mechanical function is to take up clearance and establish a precise spacing. Over time, a missing or degraded shim may lead to uneven load distribution and accelerated wear on adjacent parts. Keeping a shim in sound condition helps maintain proper alignment and reduces the risk of premature component failure. Verify the serial number or application, then call (562) 693-7748.
