This was very helpful when I rebuilt my Coot transmission, one note that for whatever reason the clutch shaft comes out as shown in your break down for the aluminum transmission but the cast steel version of this transmission it comes out in the other direction. Also CONSIDERABLE force is needed to drive the shafts from their bearings.
The caps that cover the E clips at the end of the shafts and bearings. Those get awfully chewed up on removal is there a place to get new ones?
