• The belt drive has the belt sprocket fitted to an 8mm d-cut shaft, that is held together with a circlip and some type of filler glue to stop any movement of the sprocket onto the shaft. The way we remove these is to brace the back of the shaft on the motor and tap the top sprocket to break the beading of the glue, then use two screwdrivers or similar to remove the sprocket. never attempt the brace the motor on the bearings!
