It's beliefs like this that get said and believed, and it's unfortunate because it doesn't help people that need help.
There is a drive belt in older models of the innova that delivers power to the bobbin race from the drive shaft from the motor which is located at the back of the machine but the belt we replaced was at the front in what is called the "Hook Drive Mechanism". See page 19 in the attached link.

The race doesn't rotate on it's own it needs to be powered from the motor. There is a drive belt under the machine behind the bobbin race mechanism that attaches to multiple pullies. I just checked my machine schematic diagram and they call it a "timing belt". I apologize if I used the incorrect term and confused you.
