Snow blower drive belt replacement help


I have a Craftsman 5.5HP snow thrower and am trying to replace the drive belt. I've been successful up to the point where I am supposed to "grasp the idler pulley and pivot it toward the right". This would allow me to slip off the auger belt then the drive belt. The illustrations in the manual are not clear and I've tried everything but can't determine which is the idler pulley. Can anyone help guide me? Many thanks! We're due for 6 - 12 inches of snow tomorrow!

Snow blower drive belt replacement help


In most (but not all!) drive belt situations it is the pulley in between two others (at opposite ends) that acts as the idler pulley. It could either be on the outside (most likely) or inside of the belt and puts pressure to keep tension on the belt. I had a Craftsman from many years ago that had an idler that was just a small pulley about 2" in diameter on a bracket with two bolts holding the bracket. The pulley rode against the outer edge of the belt.

thanks - I located the idler pulley but can't pivot it to slip off the auger belt. I hate to think it's because I'm a girl....but maybe I need a little more strength!

Any visible bolts holding it in place? That could be why it can't be pivoted.

Snow blower drive belt replacement help


I must have the same Sears Craftsman 5.5hp snow blower -- my drive belt (on a month-old machine!!) also just broke. And I too am staring down the barrel of a 4-6 inch snowfall in less than 48 hours (I live in southern Wisconsin). When I took the top cover off to survey the problem, my idler pulley pivoted to the LEFT (the opposite of the instructions) -- it moved fairly easily, with hardly any force. Maybe there's a chunk of crap lodged in there (which may have been why your belt broke)?
