C22 mower drive pulley

Postby staninlowerAL » Sat Apr 29, 2023 2:17 pm

Looking at the details of the drive pulley in the C22 mower parts list it doesn't show the nut as a separate part or number. Actual inspection of the drive pulley makes me believe that it and the nut is cast as one piece. Can someone confirm this? TKS. Stan

That’s correct, Stan. It’s one piece

Hi,
I guess you are talking about the lower pulley, you didn't say.
Remember when trying to remove them, the lower pulley and the nut that holds the pitman on the front flywheel are left hand threads. :)

Re: C22 mower drive pulley

Looking into this a bit closer I noticed that the drive pulley belt adjustment is made a bit different from what I can see on the pictures on the forum. Just wondering which is correct OEM or if maybe the odd one is a shop built reproduction. First 2 pictures attached look the same and the last one is missing the circle that widens the contact surface on about 3/4 of the circumference. Any thoughts? Thanks. Note: the first picture was copied from an old post while the last 2 are on equipment that I have. I can't tell much about what is shown in the parts list. Stan

Observatioins:
1 is broken.
2 is good second style.
3 is probably home-made, similar to second style.

Thanks Jim, the forum member who posted the first picture said that the adjustment bolt was broken.

You commented on #2 about being a second style. Was there more than one style? The parts list that I looked at did not show the square/rectangle plate. It could have been an earlier style. This style was not clearly shown in the pdf manuals listed here on the forum. Thanks. Stan
EDIT: I reviewed the 3 manuals for the C22 mower listed in the pdf manuals folder and the first (earlier dated one) seems to show the early style as a circular fitting with the adjustment bolt welded on to the circle part (probably a piece of pipe). The other two manuals clearly show the square/rectangle adjustment part with the bolt welded in place. I did not find any different part numbers. No indication that the different styles would not interchange. Stan

The part numbers advanced from R91 to R95, all with the same base number. The earliest ones were just a ring. Later ones added the flat plate. Since the base part didn't change, each version would backfit onto all earlier mowers.

Jim, Thanks for taking the time to explain this. :hattip: I was confident that if anyone would know, you would. I'm always amazed at your depth of knowledge. Stan

That makes two of us (I'm confident there are many more).

Hi,
The adjuster on my Cub 22 Mower has a nut above the hole in the bracket, and a lock washer on the bottom of the bracket, above the lower nut.
I tighten the nuts together after adjusting the belt tension.
The 2 nuts may be so the lower nut doesn't vibrate off the bottom of the threads, I don't know.
Below is a picture. :)

In the original version, the lower nut is used to set the belt tension. Then the second nut is tightened not only to keep the first nut from vibrating off but also to firm up the tensioner so it can't rattle around in the slot in the lower shield. The ring part of the tensioner would break once in a while, releasing the belt tension and letting the big tube bang around in the slot of the lower shield. The flat plate addition reinforced the ring and used the bolt through the lower shield to reduce vibration of the tensioner. This should have pretty well eliminated breakage of the bolt end of the tensioner. As you can see from the first picture, they still broke once in a while.

Hi,
The Cub 22 Mower owner's manual from 1952 says to use 1 nut above the bracket and 1 nut below the bracket, and the lock washer. Below are pages.
http://www.farmallcub.info/manuals/cub- ... e%2010.jpg

The nuts are A and B on this page.
