I need to fix an issue with a Jack Assembly (big and little sprocket on an axle) on a Craftsman Snowthrower, 11 HP, Model #536.886220. It appears the axle on it is anchored to the chassis by the retainer/bearings to be at a slight angle (approx 5 degrees) off from being parallel to the other axle/sprocket assemblies that has a chains going to. Does this make sense? I see one retainer/bearing is on a sheet metal section that broke a weld and moves further out of parallel alignment with heavy force. When I make sure it is back in position to the old weld position it is a little better but still a slight angle. I am going to reweld the sheet but am baffled and concerned with this. The chain slipped off recently and I found the weld break but it looks like after a fix it will still be angled. The sprocket teeth look machine to hold the change at an angle if need so maybe this is normal. Please let me know what is normal.
