A propane/mapp gas torch will aid you! I couldn't remove them with out heat!

X2 They're in there REALLY well.

If you are trying to salvage them, take two M8 x 1.25 nuts and back them against each other and tighten together. Use the lower (the one closest to the case) and turn it counter clockwise. Add LIBERAL amounts of heat to the case area (specifically to the thread area themselves if you have both the stator and clutch sides apart) and unscrew the stud.

Whenever I have case halves apart and I need a stud out, I bake the case half in the oven at 525°F and that helps.

If it's one that's already boogered up, you can use one of these:

Craftsman Stud Remover - Tools - Ratchets & Sockets - Socket Accessories

Which uses a knurled round and a "cam" action to grip the stud. PaulieB swears he removes them without messing them up but that hasn't been my experience.... They usually leave the threads boogered if nothing else.

If it's broken off down in there, you are basically stuff "trying" a bolt extractor. They generally do not end well but I have had some successes using them.

Excellent options !

im trying to salvage them i had to buy new cases and the stator side dident have any studs and iv heated them with map gas and i tried putting the 2 nuts on it and tightend them up and they still backed off

I can support the "cam" style stud removers they have never let me down, I've removed hundreds of studs out of automotive heads with them, however they usually do bugger the thread up so replacement is necessary

If possible, use an oven instead of a torch. The case (aluminum) will expand more than the steel (stud). Localized heat on the stud or around it on the case won't work as well as getting the entire part heated.

I'm sorry, I should have been more specific. I said "specifically to the thread area themselves if you have both the stator and clutch sides apart" but what I really meant was to heat the cases themselves (NOT the stud!) and you can more efficiently heat the area needed if you have the stator and clutch cover off because you can aim the heat directly at the case area where the stud is inside of to get the maximum expansion of the aluminum with minimum expansion of the steel stud.
