Worth doing on my 8526?

Thinking of doing the impeller mod with rubber paddles on my Ariens 8526 is it worth doing? Also any downside on a 4 blade impeller? Thanks!

How big is the space between the impeller and the impeller housing?
I know some only do opposite blades, but if the idea is to close the gap to make it more efficient, id say do all four.

Garage
Yes
No
The bigger the gap between the impeller blades and the housing the more benefit the mod provides.

And I'm for doing all four, too

.
Make sure the windows are up before the snow plow goes by !!

I have almost a 1/2" gap believe it or not. Hope I am doing this like thingy correct?

One of the biggest challenges I have found doing impeller seal mods is the location of the triangular gussets welded on the back side of each blade. This gusset often ends up being exactly where you would choose to drill your holes. Some people use self tapping screws which gives you a little more wiggle room, but if you intend to use nuts on the backside you have to find a location that clears this welded gusset.

There is also the never ending debate on how far you should be extending this seal into the curved portion at the blade tip. Do you only do the part that is flat, part way into the curve or the whole enchilada?

Just did it, kind of a pita to do, not hard but time consuming. I went on the flat part of impeller only, not up the curve. I made the rubber pieces just touch the side wall. I bought a rubber blade off amazon all of 10 bucks and had grade 8 bolts nuts and lock washers already (don't think I needed grade 8 but had these). If I see a big improvement I will do my Husquavarna machine as well. All I need now is SNOW!!!!
