I had to use an impact screwdriver w/ hammer to get mine off. you have to be careful though not to hit it TOO HARD and crack the motor, that would suck. I bought a couple brand new screws to re-install. I tried not to overtighten it when I reinstalled it and used some blue loc-tite. it's just a bitch.

For others in the future, check out the Impacta (yes, with an A) line from Vessel.

Heat and oil should help on this.

I used heat and penetrating oil a number of times. Each time I heated and oiled it, I'd give it a sharp impact with a small hammer to help break it free from the gunk.
