steering box seal surface repair?

[unimogger]

I'm rebuilding a 77 saginaw box, and the shaft is pitted and grooved where the two seals ride above the pitman arm. As I see it, My options are:
1: push the seals up into the box a little more, maybe they will land on a fresh spot with no grooves. There seems to be 1/8" extra before the inner seal would touch the bearing
2: Timken and SKF make .001 thick stainless sleeves to heat and press over, to provide a fresh surface. I don't know of they have one the right size. Maybe someone has used one?
3. Spray arc it, and turn it back down. Not crazy about this idea, welding on the main steering shaft.
I'm open to suggestions, as its not like these boxes are easy too source, gotta make this one work.

Speedisleeves like you mentioned in #2 is best solution i've heard of before for similar applications. I've had some success with #1 by using spacers/shims on yokes and output shafts to get to a fresh shaft area.

I used to work at a machine shop where we did a lot of spray metal work, building up bearing surfaces mainly. Metco was the name of the equipment we used, I think. Powdered metal that was fed into an oxy/acetylene torch. The shafts didn't need to be heated to the point that the metal properties were changed (not red hot.) Worked really well. Did lots of pinion shafts, bearing fits on electric motors, etc.

Looking for someone in the area to do it. If I can't find someone, I'll try moving the seals. Thanks
