Installing ASP crank pulley soon. Anyone know the torque setting for the crank bolt?

The instructions that come with the ASP pulley say to turn the bolt 120 degrees after the 37 ft lbs. The 140 degrees is for a stock cast iron pulley. Whether or not 20 degrees is going to make any difference, I don't know. Just stating what the instructions say.

 

I've done both (120 and 140 degree) on different ASP installs and it doesn't seem to matter.

 

I thought it was supposed to be 240 ft/lbs of torque????

 

The 240 ft/lbs is when you use the old bolt to seat the pulley. Then you use a new bolt and torque it down as stated above.

 

Thanks guys I bought the pulley used so it didn't come with any instructions.

 

Fully seat the pulley with the old crank bolt, go in good and tight with the new one, you wont have a problem.

 

Just make sure you torque it to the above specs. Don't give up when you can't turn it, put a pipe on your wrench! I say this because a few people have had their pulley spin right off the car.

 

I assumed he'd be using a breaker bar. I garuntee most people dont have their crank pulley at 240 ft/lbs

 

All of these specs are almost unachievable. Just get it as tight as possible. I used impact on the old bolt then a long bar. Then the new bolt I just used the impact. I have never had one fall off.

P.S. I have done this with both ATI and ASP's

 

I got mine torqued close to 240 fl-lbs by using a one-inch drive breaker bar with a four-foot length of pipe slid over the handle. If it spins off when you are going fast, it can hit the bottom of the car doing damage. Also, one guy I heard about never could find his pulley. That's an expensive pulley to loose.

 

dam...you all are weak if you can t get it to 240ft/lb...I was on the ground under the car....had the thing in 4th gear with the parking break on....had a buddy mashing down the brake pedal I had enough torque to turn the back wheels still....so I put it in 6th and pulled it again.....got the torque wrench to click over...set at 240ft/lbs of torque(of course this was a stock pulley and bolt)....man y'all are weak.
