just bought the doughnut seals, now called Motor Supports , which will need to be cut to fit the tube, and add a bit of silicone grease to help them fit into the motor tube after cutting to make them fit the motor pod the motor will sit in the lip
in the base of the Motor Support it will be a tight fit , used on DC motor , as i do not have a AC one i am concerned that they may give off heat ,
