Shaft Repair; Spedi-Sleeve Or JB Weld?

My PTO shaft has a seal-caused groove around it. I've read of repair sleeves or filling the grooves with a metal type epoxy. I have no experience with either one. What are some pros and cons for these two fixes?
 
I'm with IH2444. It would be difficult if not impossible to get any epoxy down to the desirable uniformity of surface you need on a seal. The speedi-sleeve is an elegant fix.
 
Speedi-Sleeve... and I think I'd put the green Loctite under the sleeve to seal it. I think it's 562... but it's basically a bonding agent to fill gap on sloppy parts.
I'd hate to see a new seal, tight on the sleeve and the damn sleeve leak between the shaft... It's amazing what Hy-tran can leak through.

If the groove is not real deep you can work it down with emery tape sometimes to where its smooth again.Or you can try not driving the seal all the way in so it runs in a different place thats smooth.If you do that you want to get it straight some way.If you do have to put a sleeve on it,I always put a skim of silicon form a gasket where the sleeve is going to set to keep it from leaking around the sleeve.
 
jb weld wont last a day running against a seal even if you could get it the right diameter there are 2 ways to repair, as others have said use a redi sleve and loctite to seal it, or examine the bore the seal goes in is it deep enough for 2 seals? 1 in the original location as a spacer the 2nd to seal riding on a new surface,only other way would be to remove the pto shaft, have a machine shop weld it up, and then turn it down to the right original, diameter on a lathe ,its a smal possibility these days, but if you know of a really good parts store with a really good old man in it, take the seal to him and get in the national seal book, in the listings by diameter he might be able to find a seal with the same od but a slightly smaller id, [ it will have to be a very slightly smaller id] dont waste time on the kid at the counter he will not have a clu on how to do this
 
See if Napa has a speedi-sleeve kit with a new seal. Then it will have a new surface to ride on. Hal
 


Epoxy is not a good choice ,especially if you
cannot put it in a lathe and turn it true to
the centerline and then durability is a problem.

Sleeves are available in most sizes and work
quite well.

The other option is to spray weld with a hard
nickel alloy and turn back to size in a lathe.

And we just were looking at no fix parts!!! Ha you guys fix them, the buy new parts manufactors!!!Some times two thin seals works, but thats what you get.
 
As in the case of JD "B" , you get two thinner seals and install both. Now you have twice the seal and they are both on "new" shaft surface. The groove is between them.Don't know what you are working on but maybe a different brand or application seal would do the same for you.Otherwise speedysleeve.
 
There is one other application you can do that hasn't been mentioned. I've done this on low pressure seals in fluid motors that get a groove worn in them by the seal with good results Take the little spring out of the seal if it has one and replace it with an "O" ring. Get an "O" ring that will just lay on the open side of the seal. If the wall thickness is just right you can press the ring in the seal. This will tighten the seal on the shaft. rw
