I just bought an old Bobcat model 56 which is also a rebadged Komatsu PC05-6. One of the previous owners blew out a final drive motor and decided to rip off all the drive parts and just drag it around from spot to spot. I'd love to get this unit mobile again but am dreading the cost. Does anyone know of anywhere to get used parts for this animal. It'll need bother drive motors, both idler pullys and spring tension bits and a set of tracks, metal or rubber dosent matter.. Ideas or recommendations? Thanks Tom.
