AFAIK, most two stage snow blowers don't have belt for the impeller. The

impeller is either pinned or welded to the shaft from the gear box on the

auger axle. Via gear reduction, it spins much faster than the augers. That'

sphere it's throwing power comes from. If the impeller pins are broken, the

impeller won't spin except perhaps via friction. This could reduce the

output. It could also be the gear box itself that is shot.

I understand AFAIK, but you are way off base...most use belt(s) for the auger and a friction disc for variable drive speeds.
Yes,there is a gearbox but that transfers power from fan/impeller to the auger.
