WASHER (Komatsu KO3EB-21-15160A)

KO3EB-21-15160A: A worn washer can allow fastener loosening under vibration, leading to component misalignment or failure. This aftermarket replacement part references Komatsu as the OE maker and carries the cross-reference number KO3EB-21-15160A. The washer functions as a load-distributing spacer placed under a nut or bolt head. Its plain mechanical role is to reduce surface pressure and prevent galling between the fastener and mating part. A common generic failure consequence is that a missing or crushed washer can cause the fastener to embed into the surface, resulting in loss of clamping force. Keeping a washer in sound condition helps maintain joint integrity during routine service intervals. Verify the serial number or application, then call (562) 693-7748.
