When to Replace

Replace the 421-22-12160 when the shim is physically damaged or corroded; when clearance or preload measurements show the current shim pack thickness is outside specification; when the assembly is being rebuilt and all shims must be measured and verified; or when uneven wear on the shim indicates the assembly has been operating with incorrect clearance.
