Does the inner race of the driveshaft bearing butt up to the gear that the speedo sensor reads(see first photo)? Or does it sit away from the gear a little?

Put the axle in the chassis without the bearing, when the axle is in place and still loose on both sides, slide the bearing and the metal plates in place, put the 6 screws in, just thread them in loosely. Then install the bearing-housing with the three screws on the chaincase side and tighten the screws to correct torque. Now tighten the 6 screws on the metal plates on the bearing on the picture. Assembly the rest of the chaincase and the last thing you do is to tighten the setscrews on the bearing in the picture.

(you will want to have the axle in the correct place before you tighten them, as you tighten the bolts that hold the lower gear in the chaincase , the drive axle is pulled in place)


PS the setscrews are easiest to reach if you don`t install the lower shroud-panel on that side, as the shroud will make the tool have a bad angle)
 
Aha, install both driveaxle bearings, you can install everything in the chaincase but leave the cover off.
Now press the driveshaft towards the chaincase and make sure it is in place (you should feel it stop).
Now tighten the setscrews on the bearing.
If the driveaxle wount stay properly inside the chaincase, have a friend lightly press it against it and then you tighten the setscrews.
