Im trying to pull the casing off my alternator to give it a tub and paint but I cant get anything to budge. The main nut wont move to hell or high water and the screws around the side seem pretty content just to sit there and laugh at me also, so people I need tips or suggestions on this one

remove the 4 screws from the sides. the brushes will go "click click" as they fall past the slip rings and you'll end up with the rotor still connected to the front casing and the rectifier/regulator still bolted to the back. You can paint it assembled.

Oxy torch?

Try soaking the bolts/scews with CRC or WD40 etc.

Once the bolts are off remove the brushes (unscrew the voltage regulator from the back), other wise it may be hard to pull it all apart.

yeah painting it assembled isnt really the problem, its more that its covered in grease and grime, I wanted to give it a good clean but am afraid of destroying it if water / soap gets inside it......

The easiest way to remove the main nut that holds the pulley on is with a impact wrench. If you don't posess one a mechanic should have it done in a few seconds. The other screws thread into aluminium body;they would generally release after a good soaking in penatrene, WD40 etc.

Once you have it apart, there aren't any micro circuit boards that an get hurt. Just a heap of windings and a few diodes.

If you degrease it and wash it all out with water it should be OK.

Well less paint this is what it all looks like now after a brief and very careful scrub of the alternator
