Hey
I can't see where the screw is located. If it's on front casing taking off all the other screws and prying up a little might get separation enough to use a sawsall oscillating blade or a dremmel grinding/cutting disk.
If it makes you feel any better my cr1 has a stripped out screw holding the field coil. I cut top of the screw off but bottom of the screw attached to carbon brush housing. It's rather difficult to cut going through small vent holes. The coil is toast but I have to be careful or the housing could get ruined. I used a small dremmel bit on my flex shaft tool. It's about 3/4through I need a bigger disk but disk won't fit through housing. I have an oscillating tool from harbor freight might work other wise I'm going to have to get a small file and do it by hand.
But if you can get the housing rotated and raised a hair you may be able to cut screw off. If that works use vice grips to pull out cut off screw. That way you just have to put a different screw in when you put it back together.
