Bought my first BP. J head step pulley 1hp. When I was buying, it was known there was a noise that appeared to be coming from the front pulley. Seller said they thought/assumed it was a bearing. The only thing that would alter the noise was - the lower the belt was on the pulley the louder and more prevalent the noise. As you raised the belt on the pulley it seemed to abate. I’ve begun the disassembly and the front pulley seems to be fine. Bearings and all other parts seem good. I know it’s hard to diagnose from just a written interpretation but was hoping someone may have had similar experience and could shed some light. Thanks
