I've made history. This is the first Oliver tractor that I have ever split. I've had the 1800's rockshaft casting off a few times and can do it in a few hours, but this was much easier.

Thanks to all for the input. I had this apart in just over an hour.  Now comes the disassembly and catalog of what I need to make repairs. 

I did turn the input shaft(s). I found the inner one turns the 1024 gear and the 608 and will &quot;rattle&quot; the 1041 coupling. I think I have that set to nuetral. Turning the outer shaft will turn the entire transmission or so it seems. I didn't look to see which gears I was driving specifically. 

This is interesting even if it is a little intimidating being in a transmission for the first time.  <!-- s:oops: --><img src="{SMILIES_PATH}/icon_redface.gif" alt=":oops:" title="Embarassed" /><!-- s:oops: -->
