I can't see how the set-up can work either. The roll pin is listed in the Mototrans parts book for the Strada, so it is their modification, so looking at your pictures, if the cut-out on the lip of the bearing housing engages with the roll pin, then it looks like the housing will not press all the way into the head, and if shims go between the bevel flange and the bearing housing, then what purpose would the roll pin serve?
We need a specialist to explain!

Figure 69, page 70. I think you have the same book.

Are you sure that the bearing sleeve needs to go all the way into the housing in the head? Could the sleeve just be pushed into place by tightening the bevel tube flange against it? The sleeve cannot move down because the tube is preventing it, and it cannot move up because of the lip at the bottom of the bearing sleeve.
BTW it looks like the 125 engine has a different bearing sleeve, maybe that is worth checking out.
