Normandy hub--race loose inside shell?

No pic as I don't think it would help.

My 1974 Motobecane Grand Record has its apparently original wheelset, Normandy 'Competition' hubs (ie Campy high-flange knockoffs) with Weinmann 700C rims. No obvious damage, and the alloy responded very well to cleaning and polish...they look great in fact.

The hubs are peculiar in that the front has no dust covers at all, the rear only on the drive side. So I cleaned everything out with gun swabs (think very long, one-ended Qtips with a wooden shaft), and all seemed good, except on the one side I was able to open up, the rear drive side. There, the race actually was loose, and would rotate around while I was trying to rub out the last bits of old grease. (This was particularly a tougher job because the 'grease' included something grey and very adhesive, which resisted every solvent I threw at it. Don't know what was up with that.) Anyway, I was able to get it clean but the rotating race bothered me. Surely it was not supposed to be that way. It would not come out, at least. There was no surface I could get to to apply JBWeld, but I was able to get some Loctite around the outside edge, then I spun it around a time or two, left it awhile, and finally it seemed to be stuck in place. Fresh grease and bearings, and the hub seemed to spin smooth and tight.

However. On the bike it makes some pretty strange noises, esp as it is gradually slowing to a stop. I wonder if the loctite bond has broken so that the race shifts every now and then.

I think I'm going to look for a replacement, and while I'm at it try to find a complete set with Campy high-flange hubs. (I have a set of low-flange with great new Mavic rims but it's a 126mm set.) But in the meantime...anyone seen (or heard) this anomaly?

In the two years I twiddled wrenches professionally, I saw this once. I can't remember the brand of hub, but yeah... it can happen.

This happens from time to time, usually in cheaper hubs where the press fit isn't as good as it should be and/or has deteriorated over decades of use. You won't be able to fix it, and it might not sit perfectly parallel to the other race anymore. Replace it.

Thanks for the answers, it all makes sense now. Torque, I had the exact thought about it sitting parallel. When I spun the wheel by hand it felt faultless. Spinning by hand ≠ spinning under load, though.

Oh well!

Also it occurs to me that the race might still be held in place, but it may have 'stuck' very slightly out of true as Torque noted, resulting in some noise as the cone passes from an area of less pressure to more. I have feelers out for a replacement (matching) wheel or hub, or perhaps a completely different wheelset.

Anyway, I don't think there'll be any harm in riding it this way for the short term.

The ball cup can come loose from it's press fit sometimes. Locktite can fix this if there's a compelling reason to not replace the hub/wheel. You won't always get the same bearing adjustment after though... Andy.

You have Normandy Luxe Competition hubs. They were originally sold as professional racing hubs and they weren't cheap. They have a reputation for having soft cones and they deserve it in my experience. You'd be much better off finding some Campagnolo Records to replace them. They do have dust caps. Apparently, machining was done after they were pressed in and the seam becomes invisible. They switched to plastic caps later on.

You could also use Maillard 700 hubs. Peugeot started using them on the PX10LE in 1974. Mine have lasted 38 years.

Have you priced out Record high-flange hubs lately?!

I may just spread the stays and use the 126mm Record lowflange wheelset I picked up last year.

you would need to remove the cup from the hub, and get things clean ,
Then a bit of loc-tite, the bearing seating type.. there are bigger gap filling types

John:
I actually have a couple of Normandy 'Sports' hubs around, attached to steel rims. Functionally that would answer but I'm trying to do this build 'just so' so matching wheels, etc. The hub actually is functional for short rides at least, I think at the worst there is uneven wear going on now in that race.

Bob:
The race did not really seem removable, at least not without some violent prying at the tiny gap along the edge (think a jeweler's screwdriver maybe fitting) so I figured that getting it out and back in was likely to make things even worse. I've had that happen with a dust cover that was tough to get out. It finally went back in but looked more like an amoeba than a neat disc.
