Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

Ran across this tonight on the tractorbynet.com forum.  Thought it was tidbit of interesting information.

"I rebuilt my snowblower this past summer, including putting a new band inside the drum because I was getting a lot of leakage due to wear on the impeller blades and the drum was bowed out from too many stones. I ground the impeller blades to fit the new drum diameter, leaving 0.020" clearance. We have only had one small snowfall so I haven't had a chance to give it a good workout, but with the little bit of snow we had, it worked great - it threw medium wet snow about 40 feet.
I went to the shop where my snowblower was made and was told that for a two-stage snowblower, the impeller should pick up a dime from the bottom of the drum and carry it on edge to the point of dischage a quater turn later. I was also told that when it got to the point that the impeller could not pick up and carry a quarter, it was time to rebuild. I had over a quarter of an inch clearance so I rebuilt".
