Farmall Cub

has anyone ever seen a PTO shaft without the circlip groove on it. Mine dont have one. I looked really good. i thought that it may have been shered off but thats not the case. There not one at all.

The early ones didn't have the snap ring. The bearing was staked onto the shaft.

Does anyone have pics or info on how it goes together. Im a little lost!

The staking had failed before I bought one of my tractors. I machined the lock ring groove in that shaft.

Hopefully one of these pics from TM will show you what you want. I can't locate the page in the manuals. http://www.tm-tractor.com/gpt/gpt_001.htm

I'd install the new seal into the outside of the cast housing first, then install your shaft (with bearing attached) into the cast cover housing from the inside, then once your shaft is in place, you'll install the shield with the big snap ring that snaps into the cast cover. A search will show you the easiest way to install the unit back into the diff/trans housing. I'm sure others will also pitch in to add their shortcuts.

I'm rebuilding my PTO and it had a staked shaft, no snap ring groove. I thinking about buying a new shaft with snap ring groove and I see a lot of replacement shafts for sale on ebay all the way from $15 to $70. How is the quality of these compared to the original shafts? What about the shaft TM tractor sells, anyone have one and how is it?
Are they heat treated to make them hard enough to last?

If you want to reinstall it, make sure the bearing is good, then clean the inner race good, as well as the shaft. There is a product called bearing mount that is similar to Loctite Thread Locker, but is more permanent. Put it on the shaft before sliding the bearign into place, then use a center pumch to raise dimples on the shaft . Between the two of them you should not have any more problems.

I pressed on my new bearing and it went on good and tight so I'm ok. It was originally staked two places, I re-staked it in 3 places. I didn't use bearing mount since it went on tight. I wanted to use my old shaft, I'm just not sure the replacement shafts are up to snuff.

Just a thought, I replaced the last couple with a sealed bearing. It's a 6205 (6205 2RS has rubber seals) and very common.

The last one I got through a dealer was unmarked, made in China and the same price I paid for an SKF sealed bearing (delivered!). With a sealed bearing there is some drag, but you may be able to get away without replacing the seal and you can ignore the grease fitting. The 1977 Cub had about 1/2 a tube of grease in the transmission, somebody must have pumped it 'full' of grease.... or till the tube was empty .
