I have a 91 crx Si so I have no PS and I stripped the AC why do I need a 3 belt pully? and on top of that it now has a small chip so shouldnt I replace it anyway? I heard I can shave one off is that true? Or is their a better factory balenced pully with 1 or 2 notches?

 

the CTR N1 pulley fits your needs. it lacks the rubber ring however which acts as a harmonic balancer.

 

a machine shop can lathe your stock B18C5 pulley down to one belt and rte-bal;ance it afterwards, even if the chip remains on the one belt left.

 

So their is no factory 1 or 2 belt pully I can use that is factory balanced and will properly work with my C5?
