    Nope. I changed it last month. It was a Payne in the neck.

    Can you just go back with a pillow block and re-locate the bearing an inch inward or outward?

    What is it about churches that always seem to have the equipment that's from the 60s and the widest variety of "innovative" repairs.

    One church I went to had a Carrier AHU from the early 60s and the shaft looked just like this. They used a jillion washers to move the four bolt bearing off the cabinet and past the worn spot. Bearing stands off the cabinet about 2 inches. TBH, it never would have even occured to me to do that, I was impressed.

    It was a standard repair to move a bearing in my experience. I have used four pipe couplings to move a flange bearing. Have also fashioned two channel iron stand offs. Or as they did in your case; stacks of flat washers. I would have used fender washers to spread the side loading a bit - is that what the churchies used? I have also mounted a piece of angle iron and installed a pillow block bearing instead of a flange bearing.

    Moving pillow blocks themselves either in or out is even easier - just bolt another angle to the existing angle and re-mount a new bearings.

    Replacing a shaft is a real bastard of a job by comparison. <g>

    Electricity. And everything else is insanely expensive in california. Couple that with a lack of maintenance on average and a "throw away " culture and the units dont go long.

    Can you detail out the exact procedure which would be required?

    Fill in the wear with rod then grind the shaft back round so the bearing fits nice.

    Maybe with a lathe, which if you were going to go through the trouble of getting the shaft out, why would you not replace it? I cant imagine you could do it by hand with an angle grinder, or at least, I couldnt.

    It's possible with a grinder. I have repaired trailer spindles with a welder and angle grinder before. Had to rethread them even.
    Just takes some time and patience.

    The key is to use a new wheel and use the outside of the wheel not the face. Slow and steady


    I'm not saying this to brag just letting people know it's a possible option.

    Thanks. I wouldn't have easily thought of that - and would have been concerned for distorting the shaft from the heat if I had thought of it. I think I would be doing to final-finish with a file rather than a grinder - although too, it doesn't have to be laser-beam accurate either. <g>

    99% of the time I have found a way to re-locate the bearing onto a different area of the shaft.

    Something that I proposed was to bolt a two-part sleeve over the damaged area and then use a bearing to fit the increased OD. At the time I had an excellent machine shop to fabricate the sleeve -and the shaft and wheels were really Huge so it was cost and time effective. But since then I've pondered the idea of using something like a shaft coupling - with the same sleeve-like design and maybe only one-piece if it could be slid on from the end of the shaft - and then use a large bearing to fit the larger OD of the sleeve. On a center bearing of course you would have to use a two-piece bearing.

    I am almost constantly fascinated by the fact that there are any cats with skin - there being so damned many ways to skin them. <g>

    Probably the best thing that ever happened to me in my career was working for a farmer and in the oilpatch
    There wasn't no cants.
    You figured out how to fix it. A lot of times it didn't matter if it cost more to fix vs replace you just fixed it. Just the way it was.

    Yeah I've done it. You don't need a lathe. Just get the shaft turning and use a nice file on it after brazing.
    Even done it on engine crank shafts .
    You don't squat with your spurs on.
    And you NEVER put the torches away before pressure testing.
