Cub 22 mower

[nic]

Hello,
I have a yellow 22 mower with some sort of collet holding the pitman arm to the wrist pin. I am stumped. How do I remove it to replace the pitman rod? I am only familiar with the left hand threaded nut holding the pitman to the wristpin. It is a collet with two holes drilled into it. Is this standard equipment? I can find no reference to it in the manual. the mower is in great condition, just has a cracked pitman. Thank you!

Nic, does it look like this?

I just removed the two set screws and pulled it off.

Barnyard,
Yes that is what it looks like. I would post a picture, but I do not know how to do it! I will see if I can get the set screws out. A friend told me he thought it was some sort of two piece eccentric locking ring. Nothing I am familiar with. I appreciate the help.

I removed the collar and this is what I have left to remove. How do I do it?

that is a bearing pressed on the shaft, it may just pry off if not to tight or use a bearing puller

Thank you. I have always wanted a bearing puller! Seems like a good enough reason. I wonder why they moved away from a simple lefthanded thread nut?

Final word on the mower (I hope). After drilling out the set screws, splitting the collar, and examining Barnyard's photo of his, I figured out the problem. The Pitman wrist had been installed behind the pressed bearing, preventing an easy removal. I ordered a puller, and will reinstall all the parts correctly. I will have a machine shop turn a new collet since the original is ruined. I saved the old one for a pattern. Thank you everyone for your interest.

that is a common bearing collet found on haybines and balers, even tractor supply stocks them, they are pretty cheap also

Once again, tst, and others, thank you for the information. I will look for one in my area before I have a shop fabricate one.

Also, the collar is machined with an eccentric recess that fits over a matching eccentric on the bearing's inner race. It fits loosely one way only.

Once the collar is on the bearing, you use a drift pin and a hammer to tap it around until it locks the bearing to the shaft.
