I relocated the small idler pulley by the supercharger to the recommended new location above the alternator once. But I was getting rubber bits worn off the belt, so I put it back. It was definitely not aligned correctly. That mounting point is not machined, so I thought it may be imprecision in the casting. Has anyone else encountered this?
Hi Boostmonkey,
Not sure what contributing conditions caused the "rubber bits" to show up in your earlier experiment, BUT I can tell you that like ALL of the other pulley mounting points, this cast,flat, mounting surface is precisely parallel to the face of the crankshaft. NONE of the "mounting points" on the front of your motor are machined, they are ALL cast to a similar spec. Were I to speculate, I would guess that perhaps the pulley you put in the ribbed pulley's place (next to the supercharger pulley) failed to properly control the belt (allowing it, or perhaps even forcing it, out of proper alignment with your relocated plastic pulley pulley). If you have other questions about the pulleys, I invite you to send me a PM.
Cheers,
Chris
