I am having a hard time installing a new insinkerator in a new sink.
I followed all the steps in installation manual and set the flange. When I try to mount the motor to the flange, it basically wont set firmly. The locking ring does engage and rides up the ramps but the unit is loose and falls. It’s almost as if some part is missing.
I’m not even sure how is this supposed to work. The mounting ring diameter is larger than the black plastic neck of the garbage disposal. It slides right out as shown on last photo. So how is it supposed to hold it in place? On the old unit (last photo), the mounting ring is already on the unit and won’t slide out as the neck is thicker. On new unit, the mounting ring slides on and off the neck freely.
