We broke our spindle drive belt last week and ordered up a new belt. How tight should the belt be? We first put it on hand tight (pushing the spindle motor back to get it tight) and you could see the belt whip a little when speeding up and slowing down. Also it would want to run up to the top of the pulley and make a louder whining noise after running for a few seconds. We let it run for about 3 days like this to see if it would get better, no luck. So we took it apart again and made the belt tight, put a bar between the motor and tool release block to make sure there was not any slack in the belt. Now it runs good at low rpms but above 5000 it makes a loud high pitch whine. Also the belt it rubbing on the bottom of the pulley. What it the correct tightness for the belt? or what are we doing wrong.

Thanks.
