The gray cover lifts off too from the top after removing the black plastic undercarriage, belt, and brush. Just pry around the bottom of it with a flathead screw driver and it will pop off and give you access to the motor. Unfortunately mine had more serious issues...
I thought my belt broke, so I took my 350 apart and realized that the plastic motor mount had broke off causing the gear that holds the belt on to also break off. Does anyone know where I could purchase these parts or does anyone have a hoover elite 350 that doesn't work who would be interested in salvaging the parts? Email me at clark2007@comcast.net. Thanks!!!
