WASHER (Komatsu KO01641-11220)

KO01641-11220: A worn washer can compromise the clamping force of a bolted joint, leading to loosening over time. This aftermarket replacement part references the Komatsu catalog and cross-references part number KO01641-11220. The washer functions as a load-distributing spacer placed under a fastener head or nut. Its plain mechanical role is to prevent galling and distribute tightening torque evenly across the mating surface. A common failure consequence is that a crushed or missing washer allows the fastener to embed into the softer material, reducing preload. During routine disassembly, a technician may find the washer deformed or cracked from repeated loading cycles. Verify the serial number or application, then call (562) 693-7748.
