(A quick check of AM shows that the dog gear has an OD of 1" and the low gear uses an R8 bearing (1.125") - this would work possibly)

1. Insert the rear bearing (piston side) and press it in
2. Insert the two shifted gears into the tube
3. Assemble the shift shaft with the bearings, dog, and other bearings
4. Insert through front (output side) of transmission, pressing bearings into gears as you went
5. Press on output bearing from the outer side - If I am correct, this will be fine as the wheel will hold the bearing on
6. Assemble the cluster shaft like the current way AM does it
--One bearing is flanged and inserted first
--All of the gears are inserted and the shaft is inserted from the outside, through all of the gears into the inner bearing
--The outer bearing is inserted, and the two screws hold it
7. The CIM motor is the easiest part.
8. Assemble the shift linkage - This is standard AM shifter stuff
You're close:

The dog and the bearing for the small gear need to be in before the shaft.

You have to be careful how you press the bearing for the large gear in - press on the outer race only.

How do you get the spring pin through all three pieces (dog, output shaft and shift shaft.)
