Default Underdrive pulley removal??? Help

I'm going to be tearing back into my engine tonight to replace the oil pump O-ring after mis-installing it in my head/cam swap, and I got to thinking about the pulley removal... The stock pulley had plenty of room for me to grab on the inside with the pulley removing tool I rented from O'Reilly's. Here's a shot of how I grabbed it.

Now then, when I did my install, I put on Texas Speed's 25% underdrive pulley. When I look at the picture of that pulley (here's a link to a similar-looking pulley http://www.corvettegarage.com/produc...-and-ls6.html), I don't see how I could grab it with the same tool I used on the stock pulley. Can anyone give me guidance here, please?

link not working but does the pulley have threaded holes inside the rim? If so, you'll need to use a puller that used bolts instead of little hooked teeth like this. Im assume this is the pulley you have right? If so, see the 3 equally spaced threaded holes? You need to use teh puller below to yank it

Yes, it has several holes in the center. Here's a picture of a pulley similar to what I installed. Can you get that type of pulley tool at any auto parts store?

you can rent it form an autozone if you have one near you. Yes most any auto parts store will sell this.

I called O'Reilly's, which is where I rented the other one, and they said they have this type of puller, so I guess I'm set, as long as the thread size/pitch is fairly standard... Thanks for the help!

The screw type puller is actually much easier to use than the jaw type used on the stock pulley.

That was my biggest fear on replacing the oil pump, when I installed my cam, was pinching that little blue o-ring. Easy to do and hard to see.

I feel your pain.

Yeah, the jaw puller was a pain. It kept wanting to twist on me. I wound up gouging the crap out of my crank bolt, and the stock pulley was bent and marred where the jaws gripped it.

Thanks for feeling my pain. I'm actually not that upset about it. I'm just happy nothing blew up when I fired it up. Of all the problems that could have happened, a pinched O-ring is not among the worst of cases.

worst case you get 3 long bolts in the pitch/size of the threaded holes on the balancer and use those instead of what is included. But If I recall they are a very common size and come w/ the puller. At least my ASP did. You may have an issue w/ the center puller bolt bottoming out (running out of thread) before the balancer is loose enough to pull off. You may have to put something on the crank snout to in essence lengthen the bolt.
