Damn, likely tightened 30 years ago!

Impact driver? big ass screw driver? This old motor is too greasy to risk heat

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

Suggestions?

yep, you answered your own question

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

good luck

Biggest screwdriver you can fit in the slot, maybe a little penatrant (sp)

MAP torch. Works everytime. Everytime.

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.

Very carefully

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.

GO PACK GO!

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

Capt'n Crusty says that you will DIE because you didn't put the right screws back in the engine tin!!!!

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>>>
