I'm changing the underdrive pulleys on my 4.6 and was wondering what the torque would be on the crankshaft pulley?

Thanks

I believe the torque spec for the drive belt pulley is 19 ft-lb.

19?.... If I recall it's something like 90ft lbs then an additional 180 degrees or something like that. Also make sure you use a new bolt. Make sure you find out the exact numbers.

I was off on my numbers. Here is the correct method.

1. Torque bolt to 66 lb-ft.
2. Loosen bolt one full turn
3. Torque bolt to 37 lb-ft.
4. Tighten bolt an additional 90 degrees.

Sorry, you are absolutely right. I was looking at the wrong thing.

That is it exactly, I looked it up on the Internet then found the settings printed on a sheet of paper in the box with the directions that Steeda sent with the pulley's. Mechanic is coming to the house tonight to change them for me. All I have to do is supply the beer. If he doesn't get here soon I will have to re-stock. The beer that is.Thanks guy's
