Description:Cat® Track Links, driven by the sprocket and final drive, connects the ends of a chain to form a loop, a rail for the machine to run on, and a place for the shoes to attach. Grease Lubricated Track features internally greased pins and bushings to eliminate contact and friction, each track joint sealed to retain the grease. This improves internal wear life by 25% over sealed track, decreases undercarriage noise and reduces the potential of frozen or seized joints.Application:Consult your owner’s manual or contact your local Cat Dealer for more information.
