The return Idler pulley assembly on my 46" MTD Yardman Lawn Tractor deck bolts keeps breaking and the belt mower deck belt twist, comes off and or shreds. I have replaced the bolt 4 times and the the belt now twice. I reversed loaded the bolt (so that the threads come out the top instead of underneath)) and so far the bolt hasn't broken but there is a lot of vibration on the whole upper deck drive assembly and when I disengaged the deck drive the belt comes off or twist. Any one have a solution to this problem? I am thinking that the belt is riding too high on the return idler pulley...but there seems to be no adjustment for that.
