Marty-
Look in Haynes, the 1976-1993 edition, page 2A-6, figure 7.3 and you'll see a picture of the crankshaft pulley.
Figure 7.5 on that page depicts the crank pulley on a B230F engine, not your B23. Ignote it.
In figure 7.3 you can see the front of the pulley, and the two studs and four bolt holes. Those six hold the two halves of the pulley onto the crankshaft.
John Sargent's posts covers the shims and their use/storage. There are six total. Putting more between the pulley halves makes the belt looser. And vice-versa.
When tightening the six bolts/stud nuts, do it slow and it will come out right.
Do not overtighten.
Turn the crankshaft 1/4 to 1/3 turn between each tightening. I use a 10mm socket on 3-inch (or 2-inch) half-inch drive extension to tighten the nuts/bolts by hand for a large number of turns. Also a breaker bar and __ X __ mm socket to turn the crank.
Tighten the two bolts nearest the compressor, just by hand. Turn the crank, do it again. and again. and again, ect.
Take it slow with the tightening, sometimes the front pulley half or one of the shims will try to hang up on the threads on one of the studs. Watch for that, don't continue to tighten, go back and fix the problem.
Good Luck, it's a lot easier than it reads.

PS: X = I forget the socket size.
