Campi wheel removal

Coat the back of the rims with anti-seize compound.

I always put a little anti-seize on the threads & on the mating surface between the hub & the wheel. Haven't had any problems so far.

Doug ...what are they hanging up on ??

I have been upgarding a resto'ng 6476 Suspension and brakes ...I observed a bunch a bent studs ... needless to say I had a similiar problem before. What do you see the problem as. ??

I have never heard of this. When you put the wheel back on the car, does it start to get tight on the studs, or when the centre of the hub locates inside the wheel? Do you have the original M12 x 1.5 studs? or has someone changed them for an imperial equivalent?

The studs aren't bent, they are original, and there is a lot of anti-seize applied.

It's as if the bolt circle diameter on the studs are a few thousands bigger then the bolt circle diameter of the wheels. (Or the wheels shrink when cold).

I can probably fix this if I ream the stud holes on the wheels larger.

Because the wheels are mag I've always been concerned about trying that. My wheels feel like there are hardened steel seats in the wheels, but they don't show it.

Now this happens when everything is cold. Considering the reputation mag has for expansion and contraction maybe that's the cause. I can't tell you if I can get them off easier when the car is hot because I never tried that. So much for the sceintific method huh?

You guys, the wealth of the known Pantera knowledge in the Universe are going to tell me you have never heard of this problem, issue, delema, dillusion?
I'm scared!

I have seen a similar problem where an aftermarket axle was used and it had a thinner flange than stock. This allowed the shoulder of the stud to stick out beyond the axle flange and jam in the wheel.

Hum. I'll look but they are stock studs. thanks for the input.

Mine were hard to get off. There was a lot of corrosion on the back of the rim and between the rim and hub. I wire brushed the hubs and applied anti seize compound and haven't had any more trouble. The maintanance manual recommends grease or anti seize compound because of the different type metals being in contact.

Are you sure it's the studs that it's hanging up on? Campys are centered on the hub not on the studs. It's real common for the mag rim to corrode on the hub center. Clean and add antisieze/lube.

So far what I have found with the 8" fronts is that yes, the hub locates the wheel.
No there is no corrosion but the first wheel I scraped away the paint in the hub and hit it with a brake cylinder hone.

All wheels and hubs had been previously blasted and repainted.

You wouldn't figure that .003" of paint would be a problem but so far that's the front problem.

Still got to get the rears off.

My memory is correct. There are steel inserts for the studs in the wheels.

These things don't seem to like paint. I guess the Italians figured they could save a couple of Lire by elimininating it.
