Stationary gear bearing seized to e-shaft
 

I don't have an FD, it's a turbocharged 12a FB. But since this kind of shit wouldn't really happen unless you're making some power, I figured you guys might know more about it. I cracked the rear plate at the dowel pin, lost all oil, and shut off the car about 30secs-1min after the oil light came on. Still rotor bearings and rear stationary are good, but the front stationary gear bearing seized to the shaft. I also can't get the front rotor off the shaft because of it. I really don't care about the shaft, I just need the rotor. Anyone here know the best way to get the seized bearing off the shaft?

Thats a really good question. I could probably come up with something if it were sitting on my bench but over the internet im sort of lost. If your not worried about the shaft, maybe you should look in to having it cut at a machine shop. That would be pretty cheep, im assuming.

BTW, I would love to see a picture of that.

Cutting it would get the rotor off but still leaves a portion of the e-shaft in the front plate. Also there is not much room for any kind of blade to get in and cut without damaging the rotor. IMO.:)

you should be able to set it up in a hydraulic press and press out the e-shaft. I am guessing you already have the engine down to the front rotor. So you shoul be able to set the front plate up to support the press. This will prbably render the front plate useless as well. Don't know if you planned on reusing that. I would really check the other bearings and tolerances extra close since you apparently had a catastrophic oil "event".

My vote,... long story short is a press and then heat and a press if it talks back to you.

Part of the bearing seized to the e-shaft also ripped off from the stationary gear and from the rest of the bearing, so I have just the rotor and e-shaft here, all plates are off it. I was thinking of just setting the rotor on a center plate with 2 junk housings under it and putting it on a press and press it off, but I don't know if the seized bearing will dig into the rotor. I could cut it, but a plasma torch would transfer too much heat to the rotor, and also could start a nasty oil fire. And since the shaft is hardened I'd need to change the blade in the saw to something better. I work at a machine shop, so I have access to basically anything.

Just do what I do, bang on it, cuss at it, and bang it on the table a few more times. Always works for me. On a serious note, I like your idea of pressing it out. Im sure that would be alot less hassle than cutting the e-shaft. Save that as the last ditch effort. Cutting that baby would deffinatly generate some heat, hardend steel is no fun.

Yep, I think the press is your best and almost only hope. Probably some localized heat would help expand the materials a safe amount so it would drop out easier.

I would however plan for the worst and be ready to replace that rotor as well. In case the bearing scores the hell out of the rotor and it is beyond repair. ( i'm not sure if there are oversize bearings offered. As in next ( OD) bore size up. Same ID bore for the e-shaft. Good luck, I am curious to see pics and hear the final results.

An old shop teacher told me once, "if it doesn't fit, get a bigger hammer."
Same principle applies here to an extent. ;)

EDIT: Sounds like Bee and I had the same teacher :D

Since you don't care about the stationary gear or the eshaft you might be able to use a big gear puller to push the eshaft through the stationary gear. Taking Mr. Blowtorch to the stationary gear to expand the metal a little bit will help too.

Update: Used a simple manual press, came right off. There was no damage to the surface of the shaft, but the corner had a decent burr on it from digging in to the front thrust bearing. Put shaft on a lathe and used a stone to take off the burr and plolished the shaft with scotch brite, looks perfect, you'd never be able to tell something happened to it :)
