Question Crank Pulley Stuck- NOT Crank Pulley Bolt

While installing a new pulley today I ran into an issue... I was able to easily get the crank pulley bolt off that seems to give some people problems- Yet when I tried to remove the stock pulley itself it will not come free from the motor. I tried applying even force on both sides as indicated by the install vid on HSPN. I have also tried using some PB Blaster.

I searched for a solution but so far I have not found anything useful. If anybody has run into this issue and has some advice it would be very much appreciated. Thanks!

yea same thing happened to me. You just need to wrestle that thing off. It will come off once the crank bolt is off. Be careful though since there is a keyway for the pulley.

Maybe try to tap it lightly with a rubber mallet to 'break it free'.

I tried tapping it, but I didn't have much room... I guess I'll try pulling out the fans/radiator next.

Anybody else have other ideas?

You can rent pulley pullers at some auto parts stores.

take two pry bars or screw drivers and put one on either side and gently pry back and forth to walk it off. be careful not to pry too hard on the timing cover so you dont break it. this works every time for me. and remember to put some loctite on the bolt wjen reinstalling because I have seen many crank bolts loosen and then the key way strips and efs rendering it no good

have you ever looked at the amount of space between the radiator and crank pulley. If not take a look and you will realize there is no way to get anything like that in there.

Its pretty easy to pull the radiator. I would have even attempted to change the pulley with doing it. With the rad out you may be able to get a gear puller on there.

I did try prying gently with two large screwdrivers, but to no avail...

I will def. look into the puller idea, and see if there is enough space to work with. Thanks all for the suggestions.

2 large pry bars is the way to go. The trick is to pry evenly in a jerking motion on the exact opposite sides. Make sure you leave the crank bolt in a bit so the pulley doesn't fly into the radiator.

torch/heat gun to the center of the pulley will help, just don't set anything on fire!

You would have to be extremely careful I would think. Isn't the factory center made out of rubber?

Good point, but maybe try it immediately after running the car. Not as hot as it would get under a torch but probably a lot warmer then ambient air temps.

Heck yes, my engine gets hot as hell... but wouldn't everything else get hot/expand the same way the pulley might?

but if he isn't trying to salvage the stock one, not an issue. (maybe a heat gun instead then...)

yes, but when you have one cylinder outside another cylinder, the metal expansion rates are related to the size. End result is that there will be more space between them when heated.

I had this problem also. Got the bolt out easy, couldn't get the pulley off.
I ended putting the bolt back in and torquing it down to spec. Took the bolt back out and the pulley popped right off. Strange.

Got it off this morning! It was a combination of engine heat, PB blaster, and prying that finally got it to budge. Since I had tried the PB blaster and he prying previously, I believe it was the heat that made the difference. Thank you to all for the suggestions, I appreciate the help!
