Default ud pulley help.....
I am trying to install my ud pulley....

The crank keeps rotating with the wrench as I am trying to get the 3 bolts out.
Is there a way to stop that?

am I doing something wrong?

if you can, get a buddy to help you, have him hold the harmonic balancer as you break loose the bolts, thats what we did on mine.

You shouldn't be messing with the one in the center. No need for installing an underdrive pulley.

I used the one in the center to hold the crank hub while I loosened the other 3........

I am using the UD pulley partly because my PS fluid gets crazy hot, and I already had to swap the rack once..........

alright, I aquired an alternator pulley, and cant get the stock one off.

It looks like a nut in the center, with a bolt that uses a hex key. I cant keep the rest of the assembly from rotating when I try and remove them.......help?
