hello, in many turntables the plate is the one that pushes the pulley against the motor, if you took it out, the pulley is free and does not touch the motor, they also usually have a function that with a rigid steel wire pulls the pulley when it is in position off, this brings it so that being off and someone rotates the plate manually does not deform the pulley by rubbing the plate at a single point of the same greetings
