Would any of the noise be coming from the belts? Seems unlikely, and the belts appear new, and not worn at all.Ĭan the bearings be lubricated? I don’t see a way to or mention of that in the owner’s manual. If I can determine that the bearings need to be replaced, how hard is that to do? Will I need the help of a machine shop to press the bearings in? Will I need to remove the saw’s top? It seems like I can get to the arbor shaft without removing the top, which I would rather not do. The saw is a 2001 model that I bought used, however it was only used for about a year by the previous owner and looked to be brand new when I got it. It’s not a squealing or metal on metal sound, just like a loud rumbling. (I know I’m comparing apples to oranges here) I wish I could post a sound bit of the noise here for you to hear. My second question is, how loud are these saws normally? I only have a sears craftsman direct drive 2hp saw ( mid 1970’s) to compare it to, and that thing is dead quiet. My first question is, is that tolerance normal? I can’t see where it is a problem with the cut quality. I measured runout with a dial indicator and it seems to be in the. I’m beginning to notice my 5 hp powermatic 66 seems to be making quite some noise lately, and I’m thinking it may be coming from the arbor bearings.
