Why is my treadmill making a loud whining noise?

I have a Keys 980S Treadmill that was purchased from Sears in 2001. It had moderate to low use over the years, but in the last year it was not used. We had a Sears repairman come out on 12/28/10 because it was making a loud, whining sound when we were on it. He said it might be the motor (2.5 HP or 1/50 CHP) and if so, he thought that motor was discontinued. He lubricated the old motor and it seemed to sound much better, but when we went on it the next day, it still was making the noise. Keys has apparently gone out of business, and Sears parts says they do not have a replacement motor. But the machine works fine except for this annoying noise, so is there any other issue that could be causing it? I am thinking the belt that seems to turn the motor. When I ran the machine with the motor cover off, it seemed to be somewhat better.
