Cover-belt 731-07737A

1.Removed the belt cover using my neighbors socket wrench set because the bolts were recessed.
2. Removed the old belt which was damaged.
3. Removed the clutch arm in order to put the new belt on.
4. Replaced the clutch arm and the missing hex nut.
5. Ran the snow blower without the belt cover.
6. Replaced the belt cover.
7. Started the snow blower and the belt was knocked off
8. Removed the belt cover to find out why the belt was was knocked off. Thought it was the clutch because it wasn't engaging the center of the belt and thus throwing the belt off.
9. I removed the clutch arm again to try to realign it and make it tighter. In so doing the bolt stripped the threads in the chassis.
10. I was able to find an equivalent bolt that fit the clutch arm and reattached it using the new bolt and nut.
11. Still the belt kept coming off.
12. Finally I looked inside the cover and found that there is a ledge which supports the belt. What was happening is that in replacing the cover, at least 8 times, the ledge was pushing agains the belt and thus when the the blower was started the belt was thrown off.
13. In replacing the cover I had to make sure that the belt was riding above this ledge.
14. Now it works.
15. In the process I damaged the new belt. So I am using the old belt and will probably find the equivalent new belt at a dealer such as Home Depot.
