For what it's worth the impeller in my 1999 Ariens 1024 has six blades, 1/8" thick steel.
automatic1stdown, is the impeller shaft bear metal ? Looks like it's rusted (Ariens
used to paint it). If you haven't already done so you might want to take out the shear
bolts and inject grease while turning the augers until the grease comes out the ends

Six blades! How could the snow possibly get in the housing with so much steel spinning around in there? Just kidding. That model and vintage of Ariens was a premium snow throwing machine. Something Ariens can be proud of.
Actually, Ariens had some of the best machines you could buy for thirty years or better. I just cannot fathom a company with such a respectable history and great name laying it all on the line to save a few bucks. Times are tough understandably. However, it takes decades to develop a good name. All it takes is a couple years of producing mediocre products to ruin it. I believe the reduction of the number of vanes is simply cost cutting being marketed as better efficiency. Better efficiency for getting the product out of the plant as far as I can see. Look at the backing plate. It's pretty skimpy too. If someone can explain how fewer vanes makes for a more efficient impeller, I'd like to hear the theory.

Looking at the photos automatic1stdown posted, from that point of view the impeller spins counter clockwise. As the tips of the auger blades come around they pushes snow into the impeller, which under the right conditions, throws some of it forward and to the right as the bottom of the impeller is moving to the right and very fast. I suspect that’s the cause of the leak. In light snow the auger tips don’t shove enough snow into the impeller each time they comes around to cause the impeller to throw it out. In heavy snow, the snow that would be thrown out is blocked by snow in the auger. There is likely an range of snow where the leakage is maximum and in more or less snow the leakage is less. In my opinion the leakage is a design tradeoff of the three blade impeller, which may increase the maximum capacity of the machine for a given engine power, but also results in some leakage when the snow is within a certain depth range and weight. I’m guessing, but with the three blade design the impeller may spin faster as there's more time between blades for a given RPM than with a four blade impeller. The higher RPM may be the root cause of the leakage, but also helps throw snow further. Being the leakage is always to the right side (left from behind) you can minimize the problem by clearing in a pattern such that the leakage is to the side that has not been cleared yet. That might not be possible all the time, nor necessary under many conditions.

Could it be that during assembly that someone bent that end of the auger and threw off the clearance? I would check to see if both sides measure the same... If everything is the same shouldn't both side throw leaking snow? Merry Christmas, Friiy |
