roneg wroteAll the post I have read and videos say to set the high speed or 5200 rpm the belt should be running at one sixteenth to one eighth inch below the motor sheve. In what condition would the main belt run in the higher position you describe?
"MY" procedure is to set the high speed adjustment so the belt rides the same on the motor pulley at fast as it rides on the idler pulley at slow. I feel that evens out any things that are 'weird'. The idler pulley limits the range of adjustment available(the motor pulley merely responds to that so as to maintain belt tension). I think the belt is slightly 'narrow' since it is an off the shelf automotive belt.
As I mentioned the headstock is not 'standard' since it has poly-v stuff and a non-standard belt as well as an altered motor mount. FWIW the motor is also reversible. The poly-v belt tension(eccentric setting) is set near 7 oclock(new belt). That makes the motor offset less that if the eccentric was adjusted for increased tension(towards 9 oclock).
I will review this thread so as to maybe solve the mystery. Something is being overlooked. Not tonight!
