I am trying to lacate a part # and gear for an E 550 in the paper feed drive section. It is the gear that mounts on the inside of the plate that goes up against the motor shaft of the paper drive motor on the rear of the machine. On my machine the gear is black and is angle cut to go against the worm shaft of the motor. It drives all the paper feed rollers. I have a part # but am not sure if it is correct. 6LA04324000
