I've joined the club...I blew the gearbox. I've removed the augers and auger shaft and disassembled the gearbox. I need to replace the worm gear shaft as well. Does anyone know the sequence for removing the worm gear shaft. I'm about to tackle removing the impeller blades by getting out the roll pins if I'm lucky or by cutting the shaft if I'm not. But I don't know what I'll be facing after that.

I have an "extra" brand new worm gear shaft if you just need that.  Make me an offer, and maybe we can strike up a deal.  It is pretty heavy, so shipping cost may spoil the deal.

Let me know, and we can discuss it offline.

Is the shaft damaged?.... the best way I find is too split the machine in two.. then u can easily get at the auger pulley and remove it.. then remove auger bearing and the whole auger assembly should pull right out of housing... now getting the impeller blade off can be an issue, usually they need some heat and a press to remove shaft from impeller... but maybe u get lucky and u can tap it out with a hammer..

I cheated when this happend to me.  I bought the gearbox & impeller assembly new from jacks small engine repair.  I started out like you, I was going to rebuild.  The parts were scarce for my very old Ariens (circa 1978 or 1979).  I can tell you that it was shortwork to put the new parts together and now i have the new cast iron gearcase.

The cast iron gearcase was $189; the new impeller was $95; various other parts (groove pins, thrust collar, etc) were another $25 altogether.  In the end, I was glad to have replaced it all.  The new impeller (fan) had a tighter tolerance to the impeller housing than the original and I have not bothered to install an impeller kit as the performance of the new set-up is quite satisfactory.

I lied, I missed my impeller kit and installed one later that winter.
