Re: What Happen to the MMS Pulley Install Guide? Mike Morgan updated those installation instructions... particularly, step #5.
It was supposed to be:
5. Install MMS pulley and rotate counter-clockwise until dowel pins butt up against the factory balancer.
The ATI instructions say to rotate counter-clockwise also. If you rotate clockwise, those dowel pins will (more than likely) be knocked out or broken.
Here is a link to the updated instructions on LS1.com forum:
