Review on 🔧 Gates-36313 Pulley: Exceptional Performance and Durability for Optimal Belt System Functionality by Bim Cook

Revain initially suggested another model but I was wary of this purchase so I checked the manufacturer's website checked. I bought these and everything looked fine for the size. I made a replacement, the pulley didn't spin at all. Burned my belt right in. Can't figure out why it's not spinning so I ordered a Delco AC pulley. Have this installed and checked the rotation before putting the belt on. The same thing. BTW both were made in Canada with the same box just different markings. I finally noticed a small difference between OEM and these pulleys. In addition to the bearing of the original pulley, the plastic composite has a slight chamfer. I called the Autozone and asked them to look at my pulley and it was beveled. It was also made in Germany like the original. What a headache to find out!
