Hi. I finally decided to replace my table saw drive belt with a link belt.
When I removed the belt cover I discovered that the pulley was loose on the
motor shaft. The only thing keeping it on was the belt rubbing against the
inside of the belt guard/cover. That part of the cover is nicely polished
now.

I have realigned the motor so the cover fits better, but I'm still having
trouble keeping the pulley on the shaft. There's a key in the key slot, and
a set screw in the pulley that I've tightened down as much as I can. It
might hold this time, but the first few tries it came loose after only a few
seconds under power.

There doesn't seem to be any mechanical fixture for keeping the pulley from
sliding on the shaft. Should I put some loctite on it? (I've never
actually used loctite myself; what kind should I get?) Or is there a better
way?

The instruction manual just shows a photo of someone pounding the pulley
onto the shaft with a hammer and a block of wood. I'm way past that now.
There's some blue coating on the last 1/2" of the shaft. If I don't
position the pulley near the end of the shaft there isn't enough clearance
inside the belt cover. It seems like it would be better if the pulley were
closer to the motor housing (and bearing). I sometimes hear a clicking
noise, once per revolution, as the motor spins down. It didn't do that
before, and I speculate it started because of the repositioned pulley.

What's your best advice? Thanks.
