Damn, likely tightened 30 years ago!

Impact driver? big ass screw driver? This old motor is too greasy to risk heat (IMG:style_emoticons/default/welder.gif)

i don't want to leave 1/2 in the case.

Suggestions?

yep, you answered your own question (IMG:style_emoticons/default/smile.gif)

I have a large screwdriver that I can put another screwdriver thru the handle for some extra torque....

good luck (IMG:style_emoticons/default/smash.gif)

Use the largest craftsman screwdrive and BFH.

Stripped bolt removers work well too.

Try tightening them just a little before loosening them. This often breaks the corrosion bond and makes it easier to remove them. The same applies to brake line fittings.

I use a 1/2" drive, hand held impact screwdriver with the largest tip I can get in the screw. It too, works everytime. Like Chris said, try tightening it first.

I have a big ass screwdriver that has a hex section on the shaft right under the handle. I think it is made by SK Tools. You can put a box end wrench on it and really put some force behind it.

Impact screwdriver works pretty well.

I also like a 3/8" drive screwdriver tool that I have. Can get alot of torque easy with this tool and a 3/8" ratchet.

This is the best way to get them off. Tightening first only breaks the head off too many times. Heat damages wires and rubber. Impact screwdrivers are a must for any workshop and only cost about $10.

Just make sure the tip is the correct size for the slot in the screw.

The only screwdriver that I could find with a tip that was the right size was the largest one that my local Sears stocked. It's a really big mother... Not easy to use in the 914's engine bay, but not so bad when the engine is out.

I replaced all the engine tin screws that I could with Allen-head screws. Much easier to install and remove!!

The progression of tools...

1st - box wrench
2nd - vice grips
3rd - smoke wrench

(IMG:style_emoticons/default/wink.gif) The absolutely easiest and safest way of breaking the corrosion hold on any fastener is to whack it in the middle a couple of times with a hammer and drift--the shockwaves break-up all that is holding the fastener in.

I never use a impact, for over five years now--got damn tire of drilling and easy-outing, re-tapping,,etc.

In your case, your big-ass screwdiver is the drift.....good luck>>> (IMG:style_emoticons/default/biggrin.gif)
