INSUL-MTG LWR (CAT CT21538-FK301)

A damaged lower mounting insulator can allow vibration to transfer directly into the attached component, leading to premature wear or misalignment. During inspection, a deteriorated insulator may show cracking or compression set that reduces its isolating ability. The part type serves as a mechanical buffer between two surfaces, absorbing normal operational movement and dampening transmitted energy. Keeping this insulator in sound condition helps maintain consistent alignment and reduces stress on surrounding hardware. This aftermarket replacement part references the CAT catalog number CT21538-FK301. The item ships at approximately 0.094 pounds. Verify the serial number or application, then call (562) 693-7748.
