Need help with crank pulley bolt

[2kBossGT]

Hey guys Im not sure if this is right spot to post but thought I'd give it a shot lol I need some help get this crank pulley bolt off. The motor is out of the car, the flywheels gone and I just can't figure this out :/ any suggestions would be great! Thanks

use an impact gun.

What ganzey said impact gun is ur only way to get that thing off easily

Impact gun didn't do anything for me at all

How much air you got running threw that thing ? You can heat it up a bit around the bolt head and it should come right out. Other wise use a breaker bar and you'll have to whack it with a hammer a few times that should crack it free

Pull out a spark plug and set piston at bottom on compression stroke (both valves closed). Feed in some rope onto cylinder until full (leave an end hanging out). Rotate crank until piston compresses rope and you can't turn crank anymore. Insert breaker bar in HB and pull.. After bolt is loose, rotate crank backwards till you can remove rope.

That's a great idea I've never heard of before.

What worked for me a couple of times was putting the pulley back on the balancer, wrapping the belt around the pulley once and squeezing the loose ends of the belt. Wear some gloves to hold the belt and hit the bolt with the impact, I think I hit it with 150psi not sure how much your compressor and gun are rated at.

impact gun.

if its an 03/04 cobra and your taking off the supercharger pulley, its reverse threads.

To get mine off, we had to install the transmission AND the driveshaft. two people used a breaker bar on the bolt while one held the driveshaft. ... hope yours isnt that bad!
