After almost 50 years of faithful service, the rear drive hubs of my Hawke DL11 are looking a little worn. In this case, it looks like the retaining nut was not as tight as it could have been, and there has been some fretting on the bearing surfaces. It was pretty easy to remove the bearings.
I've had success in using Bearing Mount to take up slack and "repair" outer diameter housings, but not on shafts.
Whats the collective opinion?
I’ve had my hubs fret like that too and consider it to be time to toss them.
If someone has a way to repair them I’d love to hear it.
Dave, thanks for that, probably a lot easier to toss them than get a new one. From what I can determine, all of this rear end drive was manufactured by Hawke.Quote:

You usually have to supply a bearing (a new one) and tell them the tolerance you’re looking for but a quick Google will probably locate a hard chrome shop near you. Here in CA I’ve used a shop called Chrome Craft for this https://www.chromecraftreman.com/
Hope this helps-
You can also have them plasma sprayed and turned (or ground) back to the correct dimension. You may need to have them turned slightly undersized first.
What are the pros and cons of plasma spray vs hard chrome?Quote:

IMHO hard chrome is the way to go. Have saved many high pressure hydraulic cylinders with hard chrome and they have lasted pretty much forever every time
