crank pulley removal
So I got the crank pulley bolt out and the pulley is being a pain. Is there a special trick to taking this off? I tried PB blaster and the pulley puller but the puller keeps coming loose and it doesn't budge. Could I heat it up to take it off? Any help would be greatly appreciated.

You need a good quality puller, preferably one that has a retention feature on the fingers. Although I have not removed one before from an LS1, I understand from reading GMHTP articles that they can be a bugger. I wouldn't put any heat to it unless all else fails.

What do you mean by retention feature? I rented the one from advance auto parts and it sucks. I found this 12 ton gear puller from harbor freight:

And this just normal pulley puller:

I was thinking about getting the 12 ton gear puller, what do you guys think?Last edited by 98TransAmWs-6; 07-11-2012 at 06:28 AM.

I've removed and installed a couple of these. You'll need a good quality puller like Jeff mentioned. I'm thinking Harbor Freight probably isn't the place. Do you have a good tool outlet near you? I would suppose even a puller from Sears would be better quality than Harbor Freight....
You'll also need the tool to reinstall as well. I use one made by Mac Tools, and it threads into the crank, then you turn a nut that has a roller bearing in between and it gently and easily reinstalls the pulley without screwing up the crank threads.
Some people try to run it in with a crank bolt, I don't recommend that as it can pull the threads, then your day gets more interesting
All of these tools are small enough that it can be done in the car. When you get to some of the bigger pullers like you have pictured (hydraulic) you might have a fun time getting that setup in there, because there isn't alot of wiggle room.

I have a question Jeff,,,,
Hows come when I type the word "sears" it automatically pops up in the thread as a link?? I never intended that to be a link, and threads have been closed because of these non sponsor links. Might be something Ed can address?
Just wanted to make clear so it doesn't ruin the original posters thread....

I heard the sears ones are bad quality? Also can someone show with a picture or tell me how the pulley puller should be set up on the stock pulley I feel like I am just being stupid for some reason. Is there a trick in making them not move? Also which Sears pulley puller, is this the one:

I just used a 3 jaw puller I got from auto zone. It's a bitch to get it started moving but once you get it started moving it comes right off after that pretty much. Like someone above said....don't try to pull the new one on using a bolt. Build an install tool out of metric all thread and some nuts and push the new pulley on.

Okay just to make sure I am doing it right, the arms go inside and the hooks face away not towards you right? Do you really have to crank down on the bolts for the arms, I have but they still slip off with the advance auto parts tool. I will probably try again with the tool or maybe just buy the sears one.

yeah...sounds like you have it right. What I did was get it lined up with all 3 teeth on there (can be a bitch to do just that part) then take the impact and start bumping it until it bites real good. I put the stock bolt back in to put the center of the puller on and as the pulley started coming off I would back the bolt out some.

Okay so I bought the craftsman one from sears, hopefully I can give it a try later today.

Forgot to answer your follow up question -- some pullers have a retainer assembly that encircles the fingers so that they cannot pop off.

I broke 2 pullers from autozone and harbor freight finally a craftsman one pulled it off. Just make sure that the puller is grabbing onto the 3 little "ears" near the crank on the inside of the pulley. Are you putting a stock one or underdrive on? Either way take the pulley that you are going to install and pop it into the oven at 200 degrees for about 20-30 minutes and then with oven mits grab it and it will literally just fall onto the crank, using a small propane torch and just heating the hub of the pulley for a few minutes works also.

ive done 5 cam swaps on ls style cars and trucks and just use the one you can rent from oreillys and havent ever had an issue. and when putting it back on it just lightly tapped it on with a hammer then stuck a 2x4 across it and hammered till i could get around 10 turns on the bolt then let the impact do the work from there .
