Of the projects that I have done on the car, this was probably the easiest. (Especially campared to the accumulator and fuel lines - yecchh).

The only trick here it to be careful to keep track of where all the spacers go. The exploded view in the parts manual is a help, but it does have a slight error regarding where all the washers go. Just take it apart carefully, and slip a tie-wrap through the brackets and washers to keep them together until you are ready to put it back together. When you remove the assembly, the cam access cover and the O-ring will fall on the ground. That's why the Grady belt kit includes an O-ring.

Once you have everything on your bench, remove the "axles" with the pulleys on them. This should be obvious. I pressed the "axle" bolt out with a vise, using a socket to provide somewhere for it to go.

Oh - now for the special tool. You'll need an "internal snap-ring plier" - - Sears has it. Remove the snap rings. I found it easy to knock the bearings out with a large socket with an external diameter just smaller than the opening in the pulley. Hit the socket with a hammer. Depending on how frozen everything is you may ruin the socket, but I didn't have any problem. The approved way to do this is probably with a hydralic press, but I don't happen to have one.

Clean everything up, put the snap rings back in one side of the pulleys, and use the socket to press/tap the bearings into the pulleys. Obviously the socket should contact the OUTER race of the bearings. Put on the second snap ring. Put it all back together and away you go.
