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.

You are correct. I know what I meant, but that is certainly not what I
typed.

I meant there isn't a dedicated belt for the impeller separate from the
auger. It's the auger belt that drives both. My apologies to the OP if my
response was misleading.

I wonder why they don't call it an "impeller belt". ;-)
