Flywheel screen screw removal?

[gwest_ca-(File Mod) 11,046]

My first choice is a carbon stick, battery cables and a booster battery. The stick gets red hot in a couple of seconds and the current flowing through the threads will often blow out any rust.

Carbon sticks are available from welding supply companies for cutting metal with a stick welder.

Every zinc-carbon flashlight cell also has one. Old time mechanics always had some in the tool box. Recycling is not new.

                          After you master that, then you can learn to use a periscope welding helmet.

Absolutely! Don't be like those maroons on the half hour automotive garage shows on TV - no helmet - "Oh, I'm just going to tack this support in place and finish weld it later"....

another vote for hand impact driver. 

with good, proper sized bits.

works for me.

good luck

Don't mean to hijack the thread but I have a similar issue. Wanting to put a shroud back on the top of the 14 HP on my GT 14. Find out PO twisted the head off the bolt going into the head closest to the battery. Soaked with PB Blaster then Deep Creep. Used a small left hand drill and extractor. Couldn't get extractor to bite (have had limited success with them). Moved to the next size up and got a good solid bite with extractor. Kept working and working till....extractor snapped off!

Gonna pull the head at a later date for cleaning and set it up on a jig to try again....

well, I'll add this to the mix. A small dewalt impact gun - 1/4" hex (DCF885B) and some hardened bits are fantastic on dealing with rusted screws. 90% of the time, the screws come out without a problem.

We use a different brand but absolutely agreed. 

Problem here is I'm "lucky' enough to be dealing with that other 10% of things. 

 

I'll try map gas. 

Then a good strong high quality string of expletives.

in case the impact driver fails, a set of good left-hand drill bits(M2 steel, iirc) handle the other 10%. rust is the strongest superglue I've ever found.

Be some handy if we could harness that ehh?? 

[ebinmaine 67,558]

Success!!!

My Dad wanted me to take one of these when he closed out his shop and I thought, “Humor him and take it, but you’ll never use it."

Ha. Three or four times it has saved my bacon. BTW, it also works with setscrews, but not quite as well (easier to strip the socket).

I have tapped the head sideways a couple of times. That seems to break the rust and corrosion loose. Don’t over do it or you might damage the threads in the holes

Absolutely agreed.

Living in the Northern half of the country we have this thing called rust that we deal with on a constant basis.

Some over 20 years ago a friend of mine who was an Automotive Tech shared what I thought was the best thing since sliced bread at the time.

 

When it came to steel fasteners ... "You can almost never loosen one, but you can always tighten it."

 

Didn't matter if you stretched the bolt a bit because you were going to replace it whether it was a torque to yield or not, because it was rusty.

Tighten it just a hair. Loosen it the same.

Repeat. Repeat. Repeat. Expanding your movements just a few degrees every time.

That has saved my bacon more times than I can even begin to tell you at this point.

 

Before I learned that I had broken a few and had to deal with that.

I have no idea at all when was the last time I actually snapped off a bolt or screw.

Amazing how effective they can be!
