I want to remove the two small screws holding the wire from magnetic clutch on AC compressor to feed my need to polish. I have pulled as hard as I trust myself to short of stripping the screw heads and they have resisted removal. Any tips on getting them out?
Impact is always a good thing. Doesn't look like a spot you'd want to hit with a MAP gas torch, but that's also a great go to.
I'd try CRC Freeze Off. Its a penetrating fluid that also has a lot of propellant that's intended to drop the temperature where it's sprayed by a lot. This works kinda like heat, stressing the rust and corrosion and causing it to crack, making removal easy peasy. I combine it with an impact gun though, I can't speak to how it would work without impact.
An old school hammer hit impact like I still have from my old motorcycle days would loosen them easily. I would put money on the bet I could loosen each with only one hit each. Dan
I used to run 5/8 scale race cars with Yamaha 1200cc motorcycle engines in them. Many of the cover plates on those crotch rocket engines had stainless screws into aluminum. They would be stubborn to break loose. The guy that built our engines showed me the coolest trick ever. He put a dab of what I think was some type of graphite powder paste on the tip of his screwdriver. The metal bits filled all void between the screw head and the driver tip causing it to have unbelievable holding power so you could put a ton of pressure without stripping the screw. It worked like a charm 100% of the time. Unfortunately I do not recall exactly what the product was but it definitely had ferrous grit in it. Unfortunately he passed away so I can’t ask him. But I do believe it was graphite because it was dark grey.
