I seem to remember it being the same as any other nut. Righty tighty, lefty loosey 
AIR GUN BAD 
Possible internal rotor damage. Get an oil filter wrench and wrap the pulley with a short part of a belt for grip and have somebody else pull with a BIG *** SOCKET WRENCH!

Use puller to get the pulley off, and I was only able to get Allen's pulley on right up flush to the threads, so I used a socket and mallet to get it further, then used the nut to push rest of the way. 45 ft.lbs, no locktite
I used this method after Brian told me NOT to use an impact. Although I have heard from more than a few people that they used an impact with no problems. My method is pretty easy and harmless though if you haven't used an impact yet.

No I havent used a impact yet. I tried the oil filter wrench deal allready and it broke them. Ill go to Sears tomorrow and get a large strap wrench and a bigger breaking bar and try that. Thanks for the help.

Avoid The Impact Wrench...
...at all costs! The bearings and gears will not agree with the shock loads. It may not do imediate damage but can shorten the life spans of said.
Ridgid makes a nice polyurethane coated strap wrench we use on the job. I have not tried the craftsman tool. I need to get one of the ridgid units.
I used the vice grip and belt method and too ripped the belt. I then put some thick washers in the jaws to spread the load on the belt with success.

My issue was always having the strap wrench slip during removal. I used brake parts cleaner on the rubber of the strap wrench and that kept it from slipping. I prop the handle of the strap wrench against the alt pulley and use a long wrench on the nut. The longer the wrench (breaker bar) the easier.
Yes, the nut turns counterclockwise to remove. I think the torque to put it back on is like 43#'s. That is what I have been using and never failed yet. I changed my pulley around 10x now.
