My snow blower "ate" a frzen newspaper that was under the snow and bent the Auger drive shaft and Impeller shaft
I had to separate the Auger unit from the engine/drive unit. Then I had to disassemble the auger drive shaft and gear box. I reassembled everything with the parts provided from Ereplacementparts.com and it works like new!. Saved me $600 and from having to buy a new snow blower.
