  1. I have a problem with auger belt snow is not thrown far at all.
    Then the belt snaps. Have been through 2 belts in two storms. Getting expensive an frustrating.
    Snow blowed this morning for 20 minutes and snap. Snow was light and fluffy too.
    What can be causing this? I am not experiencing any shaking.

      I'm sorry you are having this problem with your snowthrower. When a belt continues to come off or break, there is usually something wrong with a pulley or a belt keeper. Look closely at the pulleys and idlers to see if a grove has been worn into one side of the pulley. Check the bearings on the idler pulleys. If they feel rough or have play in the bearings, replace the pulley. Unless you feel very confident in making this repair, I recommend having a technician make this check and repair. You can call 1-800-469-4663 to schedule a tech to come out.

  2. Thenk you for the question. I am sorry for the problem with the unit. From the description you give I suspect one of the bearings is the problem. One of the bolts holding the bearing housing may have come loose. You do not mention any problems with the clutch tightening the belt around the pulley. Your best option would be to have the machine checked and serviced by a technician.

      I believe you are right as the idler bracket assembly wobbles very much which of course makes one of the idler pulleys also wobble with it. That should not be a loose connect should it?

    2. In response to SHC-FredM

      The pulley should not wobble. From the description you give I suspect the bearing is the problem. There are 2 741-0919 bearings. I would suggest both be replace. Both bearings are the same part.

      I am ordering parts and it describes an idler bracket assembly. Does that include other parts of just the idler bracket?
      Item #9 says assembly and I also a need pulley #53 but not sure if it comes as an assembly or what?

    4. In response to SHC-FredM

      The idler bracket assembly # 63762 and the pulley # 48883 are separate parts and will not come as an assembly. I hope this helps you.
