    To me it seems like an over tightening issue.

    Its not overtightening, you can't. The bolt had a shoulder on it that sits on the top of the boss, and you sure can't crank that bolt down too tight, i have broken two of them not being ginger with them. Below the shoulder on the bolt there is a section of no thread before the thread starts thats really skinny and makes the bolt weak. They aren't to hard to twist them off for sure!

    Oh. Yeah. I haven't pulled the bolt out yet. It's been crappy out with the fresh snow. I'll have to dig through the bolt bucket and find a longer one for welding.

    Its like they built in a failure point with that weak area between the shoulder and the threads.

    I'm chiming in because I'm searching for the pieces you guys are speaking of. I've taken off the left side cover where the clutch is housed. Is this the side to be working on? Also, I noticed strange wear on some phillips head screws...

    as I recall, I had the same sick feeling when I took mine apart.
    What in the world was loose and grinding against those p. head screws.?
    I just buttoned mine back up awaiting a thread like this one but mine looks the same.

    Hard to believe someone came to work with this great idea, which is ok but then,'
    a committee of 12 AGREED with them.
    I wonder what the 90/110's look like as they don't seem to fail as frequently.

    The shift drum stopper is behind the primary gear to the upper left of the case. Primary gear being left of the clutch assembly.

    Mine was literally just sitting on top of the primary. You can see it ground it down nicely.

    You need a spanner tool to get the clutch assembly off and snap ring pliers to remove the primary gear.

    Those screws look as if they came loose and wore on something. And that is never a good thing. Look at your side cover and all other parts for wear marks.

    I got it all apart and the lever was both bent and a little split; probably should have taken a photo. Anyway, I ran up to work and welded it back (just enough to make it sturdy and put everything back together. Not sure why, but those screws that were shaved looked like button heads. There were holes countersunk into the piece they secured so I just bought some that had the matching counter sunk heads. Rides and shifts great! No missing gears, popping out of gear or hunting for neutral. Feels like there might be
    just a tad too much tension on the lever so I'll order a new one to put in there for good measure. Thanks to all and I appreciate you sharing your knowledge

    Glad you had success jeep!

    I found a longer bolt to hold my stopper boss in place for welding on the first try in the bolt bucket.
