Problem with old Ariens belt and pulley.

Hoping someone has seen this before and has a simple answer. After having problems with my auger and drive stopping yesterday, I took the cover off the drive belt on the front of the engine. Despite the belt being relatively new (couple years old, with relatively light usage in CT), I realized the pulley that is engaged from the clutch lever is actually making contact with the large main pulley. I think this caused the pulley to stop, and the belt to be eaten up. Changing th belt isn't a big deal, I've done that before, but anyone have any ideas why the pulleys would be touching? Can the pivot wear to the point of allowing contact?

Be sure that the pulley(s) are not slipping on the shafts first of all...... maybe a key sheared and its walking on the shaft? Then look to be sure that the bearings and or bushings that support everything are not in bad shape...... no point in replacing the belt until you figure out what is throwing the alignment off - good luck!

I'd say the belt is the wrong size, i.e. too large. With a smaller belt, the idler pulley can be adjusted out, and will stop rubbing on the large pulley. I'm assuming it's a 10000 series with only one belt...

thanks everyone. This isn't an alignment problem, but the wrong belt might be a possibility. How can I determine the exact model number? The area below the tag at the rear of the machine is completely obliterated. I know it's a mid 70's machine, I think it was something like ST-732 or 734. It's a beast.My computer finally let me add some pictures to the original post. Hopefully it helps.
