Has anyone installed the fabtech pulleys and could help me. I'm having issues with the drive belt tensioner pulley, when I tighten the bolt down the pulley can't spin freely. I'm not sure if its a problem with fabtech or an issue on all billet pulleys. When I compare the OEM to it, the OEM is much thinner. The one im taking about is the one circled in blue and the one circled in purple is what the other pulley looks like. I'm just posting this on all the forums with the M113K engine in hopes someone might help.
