Install the shafts into the yoke with 2 ea 3X4 SHCS and RED loctite, matching the
flats on the shaft with the broached hole in the yoke. Use the screw to draw the
shaft into the yoke. The second shaft will be a little more difficult; using a ball
ended driver makes it a bit easier.
Assemble the front transmission next; notice the slotted holes in the front “ears”
of the cage. This allows up and down adjustment of the tail pinion for gear
mesh.
