Took the top off of the transmission on my 1954 SC.

The PTO shaft for the live hydraulics has a roller bearing that goes into a bore in the front housing. WELLLL, there is play laterally in the bearing bore. and the gear is a bit sloppy on the spline.

What have other people done to aleviate the slop in the bearing bore?
1. Do I Boston fit the bore and pound the bearing in?
2. Do I throw some braze(wont be able to get back in line though) and tighten it up that way.
3. Boston fit and put cylindrical loc tite in the bore.
4. (Thought of this one while I was typing this) use a shim around the bore and put some liquid steel in the bore?

any ideas?

Can you slide a sleeve onto the shaft? Chicago Rawhide makes something called Speedy Sleeves? or something similar in name. You might find one of those to fit the shaft. They are usually driven onto the shaft, but if the worn place is smaller than the part of the shaft that it has to slide over, you have problems. If that won't work, I guess you could weld the shaft and have it machined down to the correct size.

I'm afraid I'm not familiar with the term "boston fit". I am familiar with the bearing and plate your talking about, and would see if you can take some measurement of the bore, and if it's relatviely in round, look at getting a larger bearing that would fit. Maybe NAPA or a rep from a bearing company could help you get something closer to what you need. If its not worn round, maybe you can build up the bore itself thru brazing, and make it close to original. I've never come across a situation exactly like this, but thats what I would look into doing. Hope this helps, and keep us updated.
