    Sealed Track Pin Master

    This product contains a chemical known to the State of California to cause cancer, birth defects or other reproductive harm.


    • Track pin masters, along with the bushings, hold the track links together. The pin acts as a hinge at an adjoining bushing.


    • 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.
