Garbage Disposal Mounting Ring Stuck

Insert a screwdriver or disposal wrench into the mounting bracket on the lower mounting ring.
Garbage disposal mounting ring stuck. It screws onto the drain and then holds a mounting bracket for the garbage disposal. I had trouble getting the rusted metal ring to move to remove the old unit but i finally got that stubborn sob to turn and the disposal is off. On sep 30 2010. Make sure the disposal outlet faces the drain pipe connection.
Turn clockwise until the disposal is locked into place. As the lower ring is turned each tab grabs onto a flange red arrow the flanges are actually ramps as this side view shows. There are generally three screws that are used to hold the disposal to the flange. If a disposer needs to be removed simply tapping on the ear with a hammer will quite easily loosen the lower mounting ring.
When there is a problem with the garbage disposal chances are very good that you will need to remove it from the flange in order to work on it or replace it. Always use tongs or needle nose pliers to remove an object. Never place your hand in the disposal. A garbage disposal flange is the part of the unit that connects it to the underside of the sink drain.
So now i m trying to remove the rusted ring and the flange.
