WASHER (Bobcat BC81543-1)

BC81543-1: A worn washer can compromise the clamping force of a bolted joint, leading to loosening over time. The catalog reference for this aftermarket replacement part is Bobcat BC81543-1. This washer type provides a bearing surface under a fastener head to distribute load. A plain mechanical function is to prevent galling between the fastener and the mating surface. A concrete generic failure consequence is that a missing or crushed washer may allow the fastener to embed into softer material, reducing preload. During routine disassembly, a technician may find the washer deformed or corroded. Verify the serial number or application, then call (562) 693-7748.
