Not likely, the surfaces where the Hyatt bearings run look good. Rust in the middle is harmless but should be removed. Any surface rust on the tapered end should be polished out.
Constantine. I will gladly take it from you and any others just like it that you have!!
Even better if you are running safety hubs!

A trained metallurgist can correct me, but I think you will want to have the rusty part of the axle polished as well as de-rusted. Because of the loading on the axle, it undergoes reversal of stresses every revolution. Any imperfections in the surface finish can become the seed for a crack in the axle.
I would run it
Did you find it like that or can you explain the rusting in just a few spots? There may be defects in the surface finish making it susceptible to rust. Can't think it would wreck it though.
Nothing wrong with it. Polish it out with fine sand paper and put it together.
Just a heads up,..If that axle shaft is one of the Off shore units, so may want to check the diameter with a micrometer before installing the axle gear. They are supposed to have .002" clearance (larger than the bore of the axle gear)
The ones I purchased had almost no clearance as they were oversized, which makes installing the gear almost impossible.
That rust in that location shouldn't hurt anything.Just my opinion. Tim
I think you mean they are supposed to have a press fit, (or interference), of .002. Which, by the way, is a very heavy press fit.
Maybe "the ones you purchased" had too great a press fit? There really should be NO clearance.
If rust made Model T parts unusable there would be no Model T's...
I would buff off the rust and use that axle without a second thought if the taper and threads are good.
Charlie B, I purchased it new, and it came sealed in plastic; but the plastic got some holes in it then the whole thing got wet...I should have been more careful.
This is a spare shaft, I have no plans to use it. What's the best way to store it making sure the rust will not spread? Cover in grease then wrap in newspaper?
Constantine the axle is worthless....but I'll give you $3.00 for the rust. Leave it on the shaft and send it to me! ha
Clean it up, then coat it with a thin layer of grease, not oil, but a good grease
Didn't you finish a long model T tour? I'm surprised with the question.
James, one of the reasons why my long tour ended well is because I always like to hear what other people's opinions and their reasoning, even when I'm 90% certain I know the answer. There always could be a better or smarter way to do things no matter how much you think you know.
