163-7538: Sealed Track Group

Description: Track groups are formed when the track shoes and hardware bolt the shoes to 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. Double grouser track shoes have less penetration and traction than single grouser shoes, but better turning ability. Double grouser shoes are standard on track-type loaders and excavators because less turning resistance and greater maneuverability are needed.
