Default Removing PS pulley

I have a bad power steering leak and I'm trying to get the fluid reservior off. I'm trying to get the pulley off so I can get to the bolts that hold on the reservior. The pulley is held on by a hex-headed bolt and I'm having a very hard time getting it off, before I tear anything up I wanted to find out is it reverse threaded?

Also, any tips on keeping the pulley from spinning?

Yes the pully does not "bolt" to the pump, its pressed on, no way to get it off without the P/S Pully puller tool.

Guys he still needs to get the bolt out and from looking at the way the accessories turn I think it is reverse threaded....

It's been forever since I've done it and I'd have to do it again to be able to explain accurately but the Tool with come with Instructions (should) and from there you can figure it out.

If you mean the internal threads inside the shaft, they are standard RH 3/8"-16 coarse threads.

The pulley comes off alot easier than it goes on. Be sure you have the right setup to get it back on. I use a 6" piece of grade 8 threaded stud with a nut welded on one end, several washers, and a "free" nut. Thread the free nut onto the shaft about 3" or so, grease up the washers (and pulley bore) and put the washers against the free nut, set the pulley in place, screw the rod into the shaft as far as possible (at least 3/4"). Hold the welded nut with one wrench and use a second wrench on the free nut to pull the pulley into place. It's a hard pull, be sure you keep checking your alignment so you don't pull it too far.

^Thanks man, but I wasn't able to get it off. I stripped out the bolt that holds the pulley on, so I just took the alternator off and did it from underneath. It wasn't what I wanted to do but didn't feel like messing with a stripped bolt.

I started this today too. Got to the bolts behind the pulley (PIA) and popped the lines off the rack and got it out as a unit pulley/resevoir/pump. Started ******* with the pulley and realized there is no bolt holding it on it is interference fit. Sooooo put the pulley puller on and started bearing down on it and SNAP...... the pulley broke Cheap GM bastards made the ******* pulley outta plastic Got on the phone with Turn One and a nice billet one is on the way to my house as we speak. They look great and are designed so you can get to the bolts through the pulley so this should be a 15minute on/15 minute off job in the future. Anybody else have a love/hate relationship with GM?

not recommended, but if you decide on running manual steering, u could just break the PS pulley off and have access to the bolts. ask me how i know, i did the same thing, got frustrated and just broke the pulley off but i went manual steering

(SOMbitch):It's good to know that the pulley can be removed without removing the bolt. I was a little eerie while trying to keep the pulley from spinning, I actually broke off a piece of it...plastic POS.
I'm going to have to redo this very soon. All I was able to do was clean the underside of reservoir and lines real good and wait for it to leak some more so I can track the leak. I guess I'll just plan on buying a new pulley when the time comes. How much did you pay for a new one?

Also, did you fix a PS leak...what all did you replace if so?

Now that I know it will more than likely break anyways, that's probably what I'll do. I'm going to keep PS but I'll just press a new pulley on.
