WASHER - LOCK (Bobcat BC89517.7)

BC89517.7: A damaged lock washer can allow fastened components to loosen under vibration, leading to mechanical misalignment or fastener failure. During routine service, a lock washer's split or toothed design provides spring tension that resists rotational loosening. The catalog reference for this aftermarket replacement part is Bobcat BC89517.7. This hardware washer type functions by creating friction between the fastener head and the mating surface. A common failure consequence is that a worn or collapsed lock washer may no longer maintain clamping force, resulting in joint separation. Verify the serial number or application, then call (562) 693-7748. Keeping a lock washer in sound condition helps prevent fastener back-out in bolted assemblies.
