I installed Mr. Josh43's lightened pulley a few days ago, and I have a question now. The pulley seemed as if it was centered on the woodruff key, and tightened all the way to 100 lb/ft. If it wasn't centered, it would be crooked, wouldnt it? Also, it appears that theres a VERY VERY slight wobble to it, with no belt deflection what so ever, is this normal?
