Wheels - Bearing Surfaces Blasted

Ok, got wheels back from blasting and coating, they are all lovely and white again, however all of the bearing surfaces have been blasted as well!

I don't remember this being done the last time and I'm unsure if this will affect the fitting/retention of bearings!

Any thoughts?

as long as the bearings are tight then they'll be fine.

It's now a rough surface instead of a machined surface, meaning that part of the machined surface has been worn away, hence my concern ... there's tight and there's proper!!

I guess the only way to find out is to try, but if they're not okay then it's basically a fecked set of wheels and the £120 on getting them done in the first place!

Also, it was cash in hand, so no official record of them doing it and I can't see them paying out for new wheels without a fight (if they are gubbed)!

Not very happy at the moment  :frustrated:

That sounds rather annoying, I've always thought they should mask bearing seats etc when blasting.

That's malpractice in my book. But what would a blaster guy know about mechanics. It is not the first time I heard of a blast job turn out this way. That's why the old bearings should be kept in place before giving it to the blaster.

Besides the bearing seats I would also be concerned with the brake rotor seats. If they are unevenly blasted they run untrue.

I've never had the bearing surfaces done before, if my memory serves me correctly ... rotor surfaces yes and never had a problem, but I see where you are coming from.

I'll take some photos and a video of the surfaces tomorrow before I attempt fitting bearings, but if it doesn't feel right then I'll be going back ... they'll pay one way or the other!!

Good luck getting it sorted, so many companies are bloody useless these days.

Thanks for the heads up, when I get mine done I will mask it myself, then they will have no excuses

yeah they should of masked them  :rolleyes:  if they are still an interference fit then not to worry, but if you are concerned you can use locktite. if its good enough for a nuclear submarine then its good enough for wheel bearings.
I had a mate who had bearings that he could push in by hand and he used locktite and never gave a problem, not what i would do with loose fitting bearings but it didn't bother him  :whatever:

What a bugger, the blasting shop should know better.  Bearing fit should still be ok, the hassle would be if you were to get the surfaces skimmed in a lathe, they'll be even more oversize, not sure what the next size up bearing OD would be. Rotor mounting surface you can get cleaned up easily, a hardened washer between the caliper and mounting lug would sort out any major offset

Best of luck
I try to take one day at a time, however sometimes several days catch up with me at once.

I had similar. They powdercoated the bearing recess. That was a hell job scraping it out.Agree, leave old brgs in the wheels.

Irish in Oz

Loctite 648.
I have had electric motor bearings a bit loose in housing, centre popped the surface and loctite with great results and these things can be running 24/7.

Did similar Irish. Old car gearbox, front brg housing flogged out, basically glued brg in with 648, went for years.
