Gee TOm I wish mine had a screw. Mine has some punch-out type arrangement where you have to sort of push this way and that to get the motor mounting plate to release.

I've never tried pulling one of these apart since the last one I replaced was just plain broken and nothing I could have done would fix it and I couldn't even find the motor for it.
