   I just fixed a destroyed gearbox on a 924116.  I could not buy the gear seperate or shaft and gear as an assembly.   As far as I know Ariens does not source them anymore.  They are only offering the cast iron gearbox as a replacement which is $179 from Jacks. 

   I do know of some NOS gears and shafts though.  It's the factory recommendation to replace them as a unit but just replacing a NOS gear to a good shaft works and should hold up for many years.  If you are stuck for a gear email from the signature link below and I'll email you a gear and shaft NOS source.  The gear is $65 and the shaft I forget but he had a few left as of last week.  I bought the cast gearbox a few days before I found out he had NOS shafts comming in.

Yeah, forget the belts. You have bigger problems. It is as I assumed.

Take the snow head off from the unit. Remove the impeller drive pulley (sometimes this requires a gear puller, hopefully not). Remove the gearbox and rakes fron the housing. Remove the rakes from the gearbox. Remove all the hardware that holds tha castings together. You'll need to pry the castings apart withpout damaging them, so be careful. Use something like a utility knife to get it started, then use a screwdriver and evenly pry all the way around the seem. Be careful when sliding any of the castings or seals on the shafts. You may be able to salvage the seals, but sliding them over sharp burrs created by cross holes could damage them. You only what to take this apart once.

Check the groove pin that affixes the gear to the rake shaft. Hopefully this is sheared. If not, you'll need to replace whatever is damaged. If the gear is shot and the worm shaft is in good shape, you may be able to replace the gear only. Your unit isn't that old. Normally it is recommended the worm shaft and gear get replaced in sets.

Let me know how it goes. I don't see the groove pin in the parts manual (typo). I'll let you know what parts you need.
