ABSTRACT:
The useful life of the track components of a track-type tractor are prolonged by providing wear-compensating means within the track chain and sprocket assembly. The wear within this assembly is compensated for by providing a sprocket drive chain having pin bushing wear surfaces and a sprocket with replaceable tooth segments so that the pitch diameter of the chain and sprocket may be maintained in matched relationship by replacing the tooth segments with tooth segments having a greater root diameter as the chain pin bushings wear.
