> After about 12 years, the motor belt on my US Tower MA-770MDP seems to
loosened up. It's slipping intermittently. I can see a few cracks in the
material, so it's time to replace the belt.
I don't remember seeing any posts on this so I'll take a run at it.
What's "a few cracks"? Little cracks I wouldn't worry too much about.
You can spray some automotive belt product on it and it'll probably retard
the cracking and eliminate the slipping. It'll probably last for years like

taken the guard cage off for a closer look yet, but I don't see a tension
The tension adjustment is made by adjusting the motor mounting bolts
so you move the motor a little ways away from the other pulley and it takes
up some slack. Like I said, using some belt prep will probably take care of

the correct tension. Does anyone know?
Pull on the belt as you rotator the big pulley and the belt will
shortly come off of the pulley. To install, put the belt around the small
and push it on while you're turning the big pulley. Or try putting it on
the little pulley. Either way will work.

part (alternator belt, fan belt), or something I'd have to order from US
I don't imagine that UST goes out of their way to have a custom belt
made. Take your to your auto supply store and they'll be able to match it up
