458-7787 Link Group
General Duty Link Group
Description
The link group is driven by the sprocket and final drive. It supports the weight of the machine, provides a rail for the machine to travel on, and provides a place for the track shoes to attach.
Features
General duty tracks are designed to be an affordable option for machines at the end of their life cycle or with low utilization. Their lower initial price allows them to be run until failure. All Cat® undercarriage is backed by the Undercarriage System Guarantee. Manufactured by Caterpillar, they are hardened and quality tested to meet the productivity and performance demands of the work site.
