I am looking at an old d6 dozer I don’t know much about these cat dozers. My main question is did all of them come or have pony motors on them and if soo what years and or models. Also I am trying to find a serial number break down for these things. Also can you get reman or parts for those pony motors. I figure diesel parts are readily available.
Unless you are just playing around don't go any older than a D6C 10K.
Pony motor parts are getting harder to find and hard to use enough to keep one running. |
