Got bolster apart. Ordered seals. But need some specs on bolster shaft. The top end of shaft where the bushing and seal ride has been welded and re-turned. They didn't do a good job. Can someone tell me the O.D. Of that part of the shaft. Trying to decide whether to have redone.
 
Well after u get the seals, take the seals to the machine shop, with the shaft, they can make it fit for you, if they cant you got the wrong machinist.
 
Someone did it before I got it. Welded it up and resurfaced it. It is almost like the turned it off center. One place near the seal is rough. I'm just curious how close it is to spec diameter to determine if I want to have it redone. There wasn't a lower seal below top section or bottom section. No wonder grease everywhere.

With the shaft in that bad of shape have you considered replacing the shaft with a used one. The SM bolster shaft is the same as a Farmall M, 400 & 450 tractor. I know that I have a few used ones. Where are you located?
