WASHER (Komatsu KO3EB-15-11350)

KO3EB-15-11350: A worn washer can compromise the clamping force of a bolted joint, leading to loosening over time. This aftermarket replacement part references Komatsu as the OE maker and carries the cross-reference number KO3EB-15-11350. 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 clamping pressure evenly across the mating surface. A common generic 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 a washer that has deformed or cracked under repeated torque cycles. Verify the serial number or application, then call (562) 693-7748.
