Young Chazz-
Thanks for the reply. All of the slipper pucks are there and appear to be in good shape. The slipper plates are clean and the nylon nut is functioning as it should. The spacer I'm missing is the .013" shown in figure D8. So in your experience running without this spacer shouldn't affect things adversely? Is it normal for the spur gear itself to have some play side to side, even when the slipper is completely assembled and tightened? Mines seems to have at least 1-2mm of play.
Looks like i need to replace this main drive gear and get to adjusting and hope for the best.
