Sprocket for snowblower chute

[Grant052810]

I am looking to add a sprocket to my 3 point hitch snowblower chute. I can not seem to find a sprocket large enough to make this happen. I have ordered everything else I need to make my chute hydraulic driven using #40 chain. The diameter of the chute is 9 so that would mean I need the sprocket I/d to be just larger than 9 and o/d does not really matter to me. Maybe 11 or so. Anyone have any websites or ideas to make this happen. I have found tons of sprockets online but nothing really of this size. I have a couple pictures of what I am trying to accomplish but I am new to the forum and for some reason I cannot figure out how to attach a picture.

What brand of snowblower do you have? Have you considered matching the sprocket on the hydraulic motor to the sprocket pitch on the snowblower chute?

 

[Grant052810]

I tried. The sprocket pitch comes out to be roughly 1 1/8 I keep finding stuff that will work with 1 1/4 or 1? The snowblower is made my Braber equipment sold by northern tool. The rotation kit that they sell for the snowblower is too much money and I know with enough research and questions asked I can make it happen for half of what they want for it.

It might be worthwhile to give these folks a call and see what they have to say.

Why not use the existing sprocket / shaft and adapt a Hyd or electric motor to that? Also is this your unit? see the manual attached

Here is how someone did it.

1. It shows how they use the hydraulic motor to turn the hand crank.
2. It shows how some snowblowers use a cable instead of a gear

BTW, are you measuring the sprocket spacing center to center at the tips, or at the bottom of the teeth?

See item # in the drawing ... #28 - Turning Screw - 13002828

Nice that the gear detaches from the hand crank. Could you use that in conjunction with your hydraulic motor?

 

[Grant052810]

Yes that is it

I did think of that option but the hand crank has a lot of play in between the teeth of the chute and i have seen a few screw type cranks destroyed from a hydraulic motor.
