Removing exhaust housing - how?

[T Spool]

I have an old Turbonetics Cheetah with a broken bolt in the exhaust housing. I removed the two retainers and 5 or 6 bolts and the housing spins freely, but will not separate from the center section. Am I missing something? I want to take the exhaust housing to a machine shop to have the bolt removed.

Also, I have the question mark bracket, but in no way is it attached to my turbo. It was simply there to hold the chrome turbo cover. I believe I am supposed to have a "dog ear bracket" on the turbo that attaches to the question mark bracket. Are these universal? Will one from a stock turbo fit my Cheetah with a .82 A/R housing?

Ok, it depends if the bolt pattern on the turbine housing has the same bolt spacing as the dog eared bracket. If so, you should be able to reuse the one on your stock turbo, onto the t-netics. If not, you might be able to modify that bracket but you will have to have the turbo installed while modifying in order to get the proper alignment.
If you have removed all the bolts and turbine housing clamps and the housing will rotate, now you put the turbine housing on a flat surface and use a hammer to help remove the housing. It might take a few swift hits for the housing to come loose as the burned carbon and coked up oil is what is keeping it attached to the chra. Just make sure that your feet are clear if you have to use excessive force to hammer the housing off. Those suckers are heavy.
The way I have seen them do it in the repair room was to put the housing on a flat surface with the 3-bolt flange hanging off the edge of the work bench so that the downpipe surface is flush to the table. Then they would use a ball peen hammer to and give it a couple of swift hits while having someone hold the rest of the turbo, ready to pull the chra away from the housing when that seal does let go. Try not to let the turbine wheel come into contact with the housing when it does let loose. It might take a few tries, but it should pop off if it's a standard T3/T4 style turbo. Which the Cheetah was based off of.

I just read on GNTTYPE board the Cheetah uses a stock center section and there is even a pic of a Cheetah with the bracket I need so I just posted in the Parts wanted section for one. I don't have a stock turbo. Yes, the turbo was sitting on the header completely unsupported and yes, #2 primary cracked because of it Bought the car this way and didn't know any better until now.

So, the turbine wheel and compressor wheel are going to stay attached to the turbo while the exhaust housing slides off? Seems like a recipe for a bent shaft, but I will give it a try. Thanks Patrick.
