Todd that would have me :HeadScratch:trying to figure that one out.

Is that off the pinion gear:bigthink:?

Too small judging by the pic.

Todd,
Getting caught up on your work. Which looks GREAT! I love the new paint (primer) and parts repaired or replaced when worn. If your still removing paint I used the Rustoleum Aircraft remover stripper. wire brushes on air grinder, cordless drill, and DA sander and lots of elbow grease too. On the center pin in the axle I was having problems too. I tipped the frame/axle upside down and the old pin just about fell out! What I found was that the worn area on the pin was holding the pin in place. That may not be your problem but worth a thought.
You work looks top notch. I like that sand blaster. I would use something like that! This looks a lot like a full blown restoration to meeeeeeee! :)
Regards,
Chris

I'd pull the shifter and see there's any missing teath in the part of the trans.

Good tip there!

Todd,
Hope you find where that tooth came from.
We have a 106 in the family that always jumps out of reverse.
ljones,
I like your web site.

Thanks for the idea's guys. I'm pulling the shifter next week and see what I find there.
I and the wife both looked from the backend and there is nothing broken, so I just don't know, I'll check from the top end and see if anything shows up.
Good news, I got my steering parts Fri. and the coupler for the drive shaft, LIFE IS GOOD, LIFE IS FINE.
Went hunting tonight (this afternoon) and saw a couple does that would like to be introduced to my freezer, but not just yet.

Wow Todd, You have a lot of nice new Cub parts to keep you busy for a day or to.
I have not seen a deer. Hunted to hours last night 2 this morning and snuck out again tonight till dark. Not a tail!
Good luck filling the freezer!
Regards,
Chris

Chris shoulds like a shifter fork to me!
