So recently as I changed my timing belt, tensioner and water pump I decided to get a new harmonic balancer at the local auto parts store. I bought a doorman brand and before installing it I decided to match it with the older one to see if it's the correct one. The serpintine Groove on the pulley seems to be the same, bit the power steering grooving is alot smaller than the original one it came with. In addition, the woodruff pin was longer. Has anyone ever experienced this, if so what was the solution?
