Hi Guys,
I have an older 73" Allied-Farm King snow blower that works very well given it's age (1989 vintage). However, today I used it in what would have been perfect snow conditions and still found a lot of snow in the lower half of the auger casing - between auger and the back of the casing.
It got me thinking about the auger and casing clearance on newer snow blowers and what I have on my machine. I strongly suspect that the auger edges have worn down a lot and the result is a lot of snow left in the space behind the auger screw. I could be wrong of course, but to my thinking, the snow is supposed to be fed along the casing by the screw to where the fan / impeller picks up the snow and then it gets thrown out.
So, if any of you guys feel inclined, I would sure appreciate learning on what sort of clearance there is between the auger screw and the back of the auger box/casing - preferably on a newer blower. I would guess and say that 1/4" would be plenty to do the job properly.
If my suspicions are right and my auger clearance is indeed excessive, I have thought about bolting extra pieces to the auger spiral to close up the gap and move the snow along more effectively.
What do you guys think - is this clearance that important ? I think it is one that needs to be monitored - just like the impeller fan blades clearances. I have checked with the auger running and there is no "bow or distortion" and appears to run true. I also renewed the auger bearings just recently - the old ones were going south quickly (overheated and leaking grease).
Any input you guys might have would be appreciated - I am always happy to learn something new.
Thanks in advance
Jim
