I definately recommend taking the PS pump off and having a shop remove the stock pulley and PRESSING the new one on. This will make things a 100 times faster and cleaner. The PS pulley is desigined to be a pressed fit. It works best when you heat the pulley up to 350 degrees for about 10 minutes. This expands the aluminum about .001-.002 and makes it much easier for the pulley to go on. I would recommend that people make sure their PS shaft is clean before putting the new pulley on. Also you can lightly sand the hole in the new pulley just alittle if need be.
It can be done, but I would not recommend it unless you are very mechanally inclined and have the right tools. I have installed 2 in the driveway now. Since it's a pressed fit design it can be tough pressing on the new pulley.
I would highly recommend removing the PS pump. It's a good time to change the PS fluid and it makes the job so much easier and quicker. The Pump takes about 5 minutes to come off.

got my ps pulley fri..(bow).nice, one more to go!
Wouldn't it be fine to do yourself if you used a pulley puller tool? My local partsource (basically Canada's version of Autozone) rents tools for free. Also, if doing it by yourself, what's the BEST way (not necessarily easiest; if both are the same, then great) to press fit the new one on?
Yes, you can do it at home as long as you use the right tools.
A 2 jaw puller and a press is best. When taking the pulley off, it's best to use an impact to remove it, or use a high torque drill to suck the puller in. A rachet will take FOREVER and be a huge PITA.
If you are doing it at home and do not have a press, this is how you can do it once the stock pulley is removed.
Clean the pump shaft.
Place the new pulley in the oven at 350 degrees for 10-15 minutes. It's going to be VERY HOT so use gloves and a mit.
Place the pulley on the pump shaft as best as possible. Be quick as it ill cool fast.
In the center of the pump shaft is a hole that has threads. It might not look like it because of it being dirty, but they are there. Get a bolt and large washer. Place the washer down on the pulley, the bolt through it and start threading the bolt into the pumps shaft. This will help pull the pulley down and onto the pump shaft. Remember it's a VERY TIGHT FIT! Another way is to use a block of wood and place it over the pulley and hammer it down straight. I would recommend using a press though.
505zoom is writing up a how to.
