No .. that would make them unreplaceable. The race must be a separate part.

And the inner?
And when you say "rotors came with the race for the outer bearings already machined into them", are you saying it's only machined smooth or there is a hardened race pressed into it already. Like said above, the races have to be separate pieces from the rotor.

It still looks like you've put another race in on top of the inner race that was already in the hub. Have you???
You really need to answer that question.
BTW, the races are pressed in... not machined in.

I don't believe mfgs machine race's or cups into rotors. You say the race did not fit? They don't just slip in, they're a pretty tight fit. Did you have to install the race for the INNER (rear) bearing? From what it looks like in the photo in #415, it appears the race is NOT SEATED 100% all the way down flush. If that's the case then the rotor is NOT installed all the way back and also the reason why your OUTER bearing is sticking out so far.
You have not done the other side yet, correct?
Show us CLEAR PHOTOS of both sides of the rotors hubs - CLEAR LIKE YOUR #417 photo.

Sharp, focussed, well lit, no shadows, grease free close ups please of the other rotor hubs, inner and outer.

Remove the rotor, wipe off all the grease so we can see clearly...
BTW, did you install the INNER bearing B4 you installed the seal?
Perhaps you installed the seal then just put the bearing on top. If that's the case the bearing is not even resting on the race...

It either came with BOTH inner and outer races INSTALLED or without BOTH races installed.
It can't be one without the other.

1. Rotor w/ "inner" bearings removed (race part is still inside the rotor)
2. w/ bearings installed in rotor w/ race.
3. Position "inner" bearing will be in on spindle when installed.
Yes/No??
Are the "outer" bearings (along with its race piece) dropped through the hole into the rotor? and THEN rotor slides onto spindle???

It looks to me like you've put a second race in on top of the race that was already pressed in the rotor.
The race you put in there will have to come out.

Yep. One race stacked onto the other which was already there preinstalled.
Good thing we caught that.
You should be good to go after that, Gary.

Go back and find the post where we agreed the outer race came pre-installed.
Therefore, the inner race would have been pre-installed also.
Peace, brother. Talk in the morning.

The $Million Dollar Question is: Do NEW rotors come with races already installed?
Remember this order for the back-side of rotor;
1. Install RACE (IF NOT ALREADY INSTALLED)
2. Lay generously grease packed BEARING onto RACE
3. Install SEAL (FLUSH)
4. Install Rotor

Any of the rotors I have changed always have races installed. I have yet to see one without races.

This dude is converting "A" body car to front discs. I'm following his steps exactly and in the same order (w/out the races that came with the bearings)...beginning at 7:20....

...the only difference here is I don't need the races that came with the bearings now.....I had no idea whatsoever starting out that I might not need those
You need to buy new inner seals now. Chances are 99.9% that you messed them up pushing them in with the bearings like that.... or when you pulled it apart.
