And I'd caution against any suggestion to "dimple" or knurl the shaft. You'll always get the guy that says "..well an old millwright/mechanic neighbor of mine did it all the time and never had a problem." They usually follow up with a story about ten thousand dollar shaft on a multi million dollar machine that is still operating today and better than it ever was.
A precision knurl WITH Loctite can be a decent repair. Dimpling with a punch often results in a damaged bearing. And the dimples supporting the bearing on the power stroke side will be pounded flat pretty quick. Every time you (think) you hear a new noise you'll wonder about that bearing packing in.
