Power steering pulley tool, how to install pulley.

There is a tool to push it back on. (Don't recall if it is the same one as the puller or not.)

If yours is like mine tighten it up till you think you are done, tighten it some more THEN see if the belt lines up correctly.

Basically like said above, but in more detail:

Install the two halves and sleeve on the pulley (if the kit is like mine).
Take the long bolt, with the nut threaded all the way on and screw it into the pump.
While holding the bolt head with one wrench, turn the nut in (off the bolt) to drive the pully on.
The pain is the first try or two the bolt will want to unthread out of the pump, reset and start over until some pressure begins.
