I used my '49 8N yesterday to bush hog about 5 acres. No problems. As I was putting it away, the PTO seemed to lock up temporarily several times. After disconnecting the bush hog, I can turn both by hand. I suspect I might have a bearing failure on the PTO shaft. Removal appears to be straight forward, but my shop manual says the bearing inner race will have to be removed destructively and the new one heated to get it on. Does anyone have experience with this? How did you remove the bearing inner race, and does this apply to both bearings? Thank you in advance for any comments or suggestions.
 
Yes, I've had experience w/ this and I can assure you it's a lot easier to just replace the entire shaft, bearings and all for about $120, IIRC.

I 2nd the just buy a new 1 3/8 assembled shaft. A new, modern sized shaft is around $100 (I think this site has them at $78, as assembled shaft, housing, bearings, gasket, plus a new cover). And, literally can be 100% completed in 5 minutes or less (simple swap out, using only one wrench). I just did this. It took longer to drain the trans oil than to switch out the shaft, no joking. Seriously wondering why I didn't know about this 20 years ago.

If you buy all the parts to repair, you'll be $35-40 bucks into it before you remove the first bolt. Assuming the housing is still good and the shaft isn't twisted or bent somehow. If either of those happens, you'll be upwards of $100 anyway, well more if both are issues. And, before quantifying the value of your time. Speaking of which, expect it to take well longer than you'd expect to do the job.

Plus, the replacement allows for a easy to switch out ORC, instead of the ol' one where you must remove zerks, pound out a pin, clean up all the grease mess; all before hooking up whatever implement you want to use.
