Table saw maintenance/aligning pulleys
Seems I’m having a bit of a problem with my table saw. It’s a 10 inch contractor table saw. For some reason the pulley is slipping off the arbour. The set screw which is supposed to press against the “wood drift key” isn’t holding it in place. So when I turn on my saw the pulley begins sliding off the arbour. Should I move the motor to align the pulleys rather than loosening the set screw and pushing the pulley either in or out to align it with the pulley attached to the trunnion? I noticed something wrong with it just a few days ago when I was getting ready to cut some boards to length. It was vibrating so and you could feel the heat building up under the belt cover. Would a worn belt be responsible for the vibration? I did loosen the set screw with an allen wrench and pushed the pulley inwards. It’s not vibrating like it was before but after tightening the set screw as tight as possible without stripping it I turned on the saw to test it and the same thing was happening….. The darn pulley is slipping off the arbour. Maybe the pulleys are worn who knows. I might need replacement pulleys and a better belt. I’m trying to avoid paying out $50.00 plus for a service charge.
I’m going to bring the belt in to my local tool shop and have them have a look at it just to make sure it’s in good working order. So if it’s not the belt maybe it’s just a case of adjusting the motor to align the pulleys. I’ve read the manual and it wasn’t much help. all it said was to use a straightedge to make sure the pulleys were in alignment by loosening the set screw and adjusting the pulleys either in or out. I was talking to one of the men at the local tool shop and he said it could be the belt or it could be a missing “wooddrift key”. (a small piece of metal that slides into a groove in the pulley which the set screw screws against holding the pulley tight to the arbour) Well I know it’s not that.
