    I'm just guessing the phillips head screw is what's holding it together. Maybe some penetrating oil on the screw might work.
    What it that?

    Used a screw driver that is made to hit with a hammer.

    Use an angle grinder to cut a slit in the case all the way across like you would do to open a compressor from a A/C window unit. Should fall right out

    #4 phillips bit ?
    Failing that, I guess a chop saw or grinder would work wonders on the bell.

    I have unwound those Copper wires sometimes, most of the times the wires flat & I could grab a end & push the wire & there's enough cross section strength in it so that won't bend much.

    But, yeah CRC & a impact driver.

    I use a old big fat Phillips screwdriver too, I force the tip into the screw head & then twist it anticlockwise a bit so it pushes itself out of the screw, while still putting a lot of force into it, then I bash the screwdriver head with a hammer.
    It acts as a impact driver & often breaks the screw loose.

    Next option is to chuck it in a fire & burn the insulation off & the heat/expansion often breaks the screw loose.

    Yep ... tapping the philips head screwdriver with a hammer might work. You would just have to be careful not to strip the head of the screw. My old Suzuki Samurai was assembled with #3 phillips head screws and they could be a real bugger to get loose even with the impact tool.

    I thought of a couple more options.

    MSM could heat the phillips head with an oxy acetylene torch and then feed in some paraffin ( candle wax). That's about the best thread lube that i know of. Just heating the screw head up to cherry red should be enough to break the bind.

    It may be that the specialty tools aren't available but most everyone has a 3/8" drill. He could just run a small drill into the centre of the phillips cross to make a pilot hole and then drill the head of the screw off with a larger bit.

    If that one screw is the only thing holding it together ... it should just come apart when you remove the screw.

    To add to Hills second response, the heat of the torch outside the screw on the casing will expand the casing allowing easy removal of the screw if that is the only thing holding it. It is common to heat the lug nuts to make it easier to remove a rusted wheel. If not, the torch is right there to cut the casing in any manner you desire.
    Give back more to this world than we take.
