If so the the right side pulley ( discharge chute side ) is the tension pulley.
Also if so I can not follow what you are saying about different bolt holes .
According to Jacks the part number is # 95404060 an according to Gates it is equivalent to a 6776BR belt which is 1/2 x 96.48".
Are you sure you are connecting the PTO cable to the right place on the tension plate # 44 in the image above ?
