Table saw belt drive

My Grizzly 10" 1.5 HP table saw is belt driven. The pulley on the motor has come lose. I have tightened the screw that hold the pulley on the motor as much as I can using a socket wench and it will not hold. Nothing seems to be broken. How can I make the pulley stay put?

Welcome to the forums.

The pulley should fit on the shaft fairly snugly. If it's too loose no amount of tightening the setscrew will help.

Is there a flat on the motor shaft ?

Better still on a 1.5HP motor there should be a slot cut in both the pulley and motor shaft, with a tight-fitting key inserted to lock the 2 together. The setscrew is only there to keep the pulley from walking off the shaft--the key is what locks the pulley from spinning. Maybe yours got past final inspection and left Taiwan without the key.
