Sealed and Lubricated track Sealed and lubricated track surrounds the track pin with lubricant to virtually eliminate internal pin and bushing wear as a maintenance consideration. Positive pin retention locks the pin to the link to prevent "end play" or "pin walking". Hydraulic track adjusters, track guiding guards and two piece master link standard. Features large pins, bushings and bolts with positive pin retention which leads to long track seal life. |
