Looks like you are working your way though this nicely. That's a lot of stretch on the chain. What were the symptoms/problems you were having with it? How many miles were on it?
It had just under 160k on it. When I was driving you could hear the chain (at least I believe it was the chain). But I believe the big problems were caused by the chain because there were a few bearings that just sounded like they had sand in it lol. But it was a clunky noise at first, then the faster you went the more constant the noise was. Then about 35 mph it was shaking everything. When I started taking the t case out there were bolts shaken loose and a few that were gone from the transmission bell house bracket thing that's in between the lower oil pan and trans. (Sorry I don't know what that piece is actually called) while I was driving on the highway there was a pop and the t case was shaking so bad that I got death wobble the vertical version lol.
Great work so far! I don't want to jinx it.
Thanks for sharing and good luck with the rest of the rebuild!
Be sure to mount that "kill" on your garage wall or the side of your tool box. Years from now you can look at it and remember all the joy and frustration of your fix. I have a cracked syncro ring out of my 4 speed Muncie that I keep on my tool box. Rebuilding that was very fun pre-YouTube/forum era. It's so rewarding to find the definite cause of your problem.
