2A-3241: 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. Track Bushing Masters are found within the master link on the link assembly. Attributes: Sealed track has contact between the internal pin and bushing causing wear to begin immediately because of the friction between the two parts. This results in a significant increase of internal wear life of the link assembly. Grease Lubricated Track link assemblies are direct replacements for sealed link assemblies on Cat Hydraulic Excavator models.
