SPACER (Komatsu KO3EB-15-21370)

KO3EB-15-21370: A worn spacer can disrupt the precise alignment of components it separates. This aftermarket replacement part references the Komatsu catalog number KO3EB-15-21370. The spacer maintains a fixed gap between two parts, preventing metal-to-metal contact or unwanted movement. If the spacer fails, the affected assembly may experience loosening, vibration, or accelerated wear. Keeping a spacer in sound condition helps preserve the intended clearance and load distribution. The part is a simple mechanical shim that does not require adjustment after installation. Verify the serial number or application, then call (562) 693-7748.
