I was given a Bissell Lift-off Revalution turbo?

I Love this little Bagless wonder,However it needed cleaned when I got it home. Itook the canaster apart to clean it and was about to get to the upright,when bamb something fell tipping my full beer right into the motor, Igrabbed it quick tip-ped it up side down let it rest a week. all dry but sticky and smelling of stale beer,so Idid what any normal person would do Itook it apart down to the motor , QT's toothe picks, Brushes,not asticky smelly spot. BRAND NEW if not better I've used the canaster a couple times. seemed to work fine but found a little to much dust and to many screws. Idont have the upright together and missng screws in the canaster. Is there any way to find out where the screws go so Ican use my new used LIFT-OFF ?
