Delta Unisaw, 3 hp, 220V, 1993 not used hard but often. Replaced worn belts 5 months ago and now its making an intermittent sound like metal on metal, high pitched but not a shriek. Its not the arbor bearings for certain. Checked pulleys, those are tight. Using a screw driver through the throat, I can pry against the drive pulley and get some slack on the shaft transversely through the motor, maybe 1/16" Squirted some oil on shaft between pulley and motor and it quieted down.
I can get my hand on the lower pulley to lift and I do not detect any play in the shaft vertically, though granted that's hardly a good test.
Does this sound like a bearing going bad in the motor?
Are motor bearings (I assume the sleeve type) be replaced or am I looking at anew motor?
