So, I'm trying to install a 185 pulley and my buddy and I got stuck trying to remove the Crank pulley. We used ProjectMayhem's suggestion of using an extension to brace the pulley while using a 3/4 Breaker bar. That didn't work so we then used a Crank Bolt remover type thing that apparently removed 2JZ crank bolts which are torqued to something ridiculously high and that failed to work as well

The reason why I'm changing is due to my OEM crank pulley separating. The inner rubber piece is not flush with the rest of the pulley but we think that the reason why we cant get the crank bolt off is due to the separation (have pics on my phone, will post later). This is all speculation but I can't see why it would be so hard for 2 people using a lot of strength on a breaker bar and it not even budging. We're going to put the car back together tomorrow cause we're both tired so hopefully nothing worse is wrong with it

Any info or insight would be appreciated.

We couldn't get his impact gun to fit in there due to the radiator and we didn't feel like taking the radiator out cause of the trans cooling lines going in and out and he has reason to believe that the impact gun probably wouldn't put out as much torque as a breaker bar with a long pipe extension would. Worst case is I put the engine back to stock and take it to the dealer and hedge my bets that they'll be able to get it off since they'll probably have higher torque tools
