My buddy has a 500 tbx that is making asorta of a growling sound form the belt cover area. It does in in any gear high,low and neautral when you rev it up took the cover of and can not see anything wrong. Still a little noise with the cover off but not as bad .any ideas?

 

are the nuts on the clutches tight? is the belt within specs? any drivability issues?

 

The nuts are tight the only thing we noticed about driving it it seems to be under a load when tring to move and while moving. Not sure on th belt spec
