227-3029: 73.42mm Outer Diameter Track Master Bushing

Description: Track bushings, along with the pins, hold the track links together and are part of the sealing arrangement between the link and the bushing. Attributes: 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. Stepped wall bushings have a larger diameter in the wear area to provide additional wear life.
