Ah! That's easy. Look at the engine on the stand, from behind the stand, such that the flywheel end is facing you and the fan end is away from you. The case half to your left is what is bolted to the stand. The case half to your right is not. Turn the engine 90 degrees counterclockwise such that the right-side engine case half is pointed up.

Common fasteners to forget, which cause you to swear and curse trying to figure out why the case won't split:
-The 3 13mm nuts behind the flywheel
-The 1 15mm nut at the bearing saddle in the timing chain area
-Each and every perimeter nut (I usually miss one the first time around)

You'll also have to liberally apply your rubber mallet!

Who is H.G.P.?

That's the answer I was looking for! (The original title of the thread) Thanks!

Now it makes 2-46 and 2-47 quite clear.

1. Incidently, what is the engine apparently sitting on in 2-45 and 2-46?

2. Can I do everything with this adapter ring http://www.pelicanparts.com/catalog/images/Tools_folder/enginestand-mainely.jpg as the yoke?
What's the difference(s)?

The only difference you are going to find in using it is just the cost. About $100 difference.
