BUSHING (Komatsu KO3EA-64-A5120)

KO3EA-64-A5120: A worn bushing can lead to excessive play in the pivot point it supports. This aftermarket replacement part references the Komatsu catalog number KO3EA-64-A5120. The bushing acts as a sacrificial wear surface between moving metal components. Its plain mechanical function is to reduce friction and absorb vibration at the joint. When a bushing fails, the resulting looseness can cause accelerated wear on the surrounding hardware. Keeping a bushing in sound condition helps maintain precise alignment and reduces noise during operation. Verify the serial number or application, then call (562) 693-7748.
