Hi guys- My brother dropped off an OC-4 for me to play with. We're trying to figure out these tracks; the grouser or pad is offset from the chain, meaning not centered on it. I've never seen a set like this, but then again I haven't looked that closely. There is only 1/2 to 5/8" clearance between the track and some frame parts.  Is this an original track or did someone cut them down? They are pretty well worn, and I'm watching for a better set. I found an 8" wide set from an OC-3 that I think will work. In the past I've seen 10" and 12" from an air track drill but they are too wide unless the track frame and sprockets are spaced out. -Gerry |

My guess is that these were cut down to better fit your machine. Probably used up ten cut-off discs doing it  Offset tracks were not factory output, I am quite sure. The grousers have been built-up too. The 8 in. set from that OC3 will work, but you'll need a few extra pads. |

Chris: there were some OC-4 tractors built with just 3 lower rollers like an OC-3

Tell us more, John.
I actually have an OC4 with OC3 track frames and therefore just three rollers per side, but I just assumed some cheap #@! swapped out the proper tracks frames for spares from an OC3. Everything else is pure OC4.

We have a Cletrac around with one side cut off the tracks. I think it's a model AD. Not sure whether those tracks would be factory or not. I know one of the ADs has B tracks on it, but I don't think it is the one that's cut.

I've never seen any Oliver or Cletracs with offset track pads. I have however seen Case crawlers that had them that way from the factory. In reference to the OC-4's with 3 roller track frames, I do have literature that states they had 3 or 4 (optional) rollers per side. That must have been very early production as I have never seen a 3 roller OC-4.

I think I might be able to help. I am in Washington and trying to post an OC 3 for my uncle. it has good tracks and finals with a model S Carco winch. I haven't been able to get anything to post so I thought I'd come ona and see if someone might be able to help or just pass the word along. I am not a computer expert. If you might be interested please contact me I do have some pictures of it.

I had photos as well of a OC4 that someone sent me, it too had the 3 rooler rails, and these same offset tracks/pads. I think it was becuse it was a 31 gauge ? unit Really narrow machine
I think I posted on this on one of the forums too at the time.
Wished I bought that machine, looking back..
