The front of the impeller is connected to a shaft through the impeller itself. The front of the impeller shaft is connected directly to the spiral gear housing (i.e., the auger gearbox). Hope my description is adequate.

Thanks for that link; you might be on to something...
"I think the main cause was that the gearbox shaft was not set deep enough into the fan splines. There is alot of in and out adjustment for the gearbox and you could tell only half the spline depth was engaged. I'm also thinking that the PO engaged the PTO at full throttle and not at idle."
When I reassembled everything, I vaguely recall being concerned that the splines on the gearbox / impeller shaft did not penetrate deeply enough into the mating splines on the impeller (fan).
I had hoped for a 'magic bullet' fix, since the blower is mounted on the tractor, and I was hoping to avoid removing the auger / gearbox / impeller assembly. I'm starting to think I'll need to look at the splines to see what's up.
Any other ideas? Anyone?
Thanks a bunch!
Jon
