Resecure the first screw in the drive sprocket onto its flat on the shaft, then secure the other screw in the sprocket. Rotate the hand wheel several times to insure the belt remains centered on the driven sprockets.

Reassemble the cast-off plate assembly to the cast-off plate holder. secure both screws.

Align the take-up cam within the cast-off plate assembly. Secure both screws in the take-up cam. Rotate the hand wheel several times to insure no rubbing between the cam and the plate occurs. Reassemble all covers to the machine.
