Impeller Mod for Troy-Bilt 2410

My TB 2410 does OK, but I thought that it could do better throwing snow with the addition of an impeller modification kit. So, I ordered a kit, which arrived today and I had some time on my hands.

I removed the discharge chute for better access to the impeller.



The standard impeller is a bit rounded on the edge, and has about a 3/4" gap between it and the escape chute housing. So, that explains why it tends to be a bit incapable with lower volumes of snow and the heavy wet stuff.





By contrast the impeller on my Toro 521 is much more like a clever and is tight to the discharge chute housing.


The mod kit is comprised of rubber paddles, metal backings and related hardware. I cut and shaped the backing plates to the shape of the impeller blade.


Then it was a matter of cutting the paddles to the proper size and shape.


Continued on next post . . . .

Next post . . .

I did some measuring and figured that the paddles should extend from the edge of the impeller by about 3/8". So, I made a makeshift fixture to position the paddles on the blades for drilling of the bolt holes.


I had to remove the base of the discharge chute to get better access for drilling


Then I was able to drill the holes . . .


Here are the paddles installed.


The clearance on the bottom of the impeller housing looked OK.


But the clearance at the top of the housing was a bit tight.


So I did a bit of sanding to reduce the interference fit. and things looked OK. Here is the modified impeller with the discharge based re-installed. The clearance is much tighter.


So, I got the machine back together and thought that I would run it for a while to check things out and "break-in" the paddles.

Bad News: I may have not provided enough clearance or something, because 2 of the 3 paddles fractured after a few minutes of running. I think part of the problem is that the rubber paddles are not fiber reinforced, so they are likely to fracture.

Perhaps I should get some reinforced rubber strips and replace the paddles . . .

I am about to use baler belt for impeller mod (as Kiss4aFrog always suggests). I got it delivered today.
It should be very durable and it's also inexpensive.
What some members recommend for "break in period" is to lightly coat the auger housing with grease and run the blower for a few minutes for the padles to seat in.

Thanks for the tip on the baler belt guys. I will be out and about over the Thanksgiving weekend (Black Friday, etc) and will see if I can find a Tractor Supply Corp. Would Harbor Freight have anything like it?

Here is a picture of one of the fractured paddles . . 2 of the 3 fractured during break-in, but I am thinking the other would fracture under the load and the cold.

I was thinking this might happen since the kit had plain rubber and not fiber reinforced.

Yes, that is what I got (I payed more since the one I got was 6" wide, ordered 10' and had to pay shipping).
What you posted seems to be the best value (and it should be good for about either 5 or 10 3 blade kits).
You can always order on line or just walk into a store and buy just one foot of it.

Actually, I think I found something that I can use . . .

I have a 2-foot section of "Trident-Ply" 4" diameter Marine Exhaust Hose, which has several layers of ply in it and then more fiber ply on the outside. It is left over from my boat engine rebuild and has been sitting in the garage for about 4 years.

The impeller paddles are about 2" x 3", so I can cut 3" off the end of the marine hose and then cut that into 2" sections. They will have a bit of a curve to them, but I do not think it will matter much once they are clamped to the impeller.

tpenfield, you may need to do something about those 2 bolt heads. That may be what caused your kit to break off. Search around for some replacement flat head bolts like this.
