Otherwise, use heat.

the impeller on my old Ariens is roll pinned to the shaft. so was the impeller on an old Bolens I broke up for parts.

Correct, I forgot about the roll pin. But anyway, on some models, the entire shaft, with the impeller attached, will come out as one unit.

It is a sears craftsman dual stage snow blower model C950-52730-7 11HP 30 Inch Snow is expected again soon so any helpful advice is appreciated!
