These have two spacer "buttons" held together by a long roll pin. Be sure these are in place and the roll pin is not broken. These are needed to properly adjust the axle end play.

I took mine apart before installing it, best now than have to tear it down again.

I would mark the case at the seam so you know how it aligns when putting it back together.

And, the clutches are in a specific order....in a specific direction, a couple are concave, so it's important to keep them in the exact order.
