Sprocket for snowblower chute

[Grant052810]

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?

I measured the closer to the bottom of the teeth.

My Meteor snowblower has a sprocket on the bottom of the chute that measures 1.0" center to center at the bottom of the teeth. That would be a #80 roller chain.

Oh shucks,
I used an old winch (like $50/$60 $ or so) and reconfigured it so that it turns nice and slow and can actually break ice frozen chute loose.\
And that is like 4-5years going on now.
Not magic simply an analysis of available torque and some DIY capabilities.
The nice up come is that nice low investment vs outlay.
Bonus is it works!

Here is a 40 pitch 80 tooth (13" Outside Diameter) Sprocket on ebay for $30 + $26 shipping. You would have to cut the center out. At least ot gives you an idea of tooth count and size;

Teeth OD
66 10.796 10.508 10.195
67 10.955 10.667 10.352
68 11.115 10.826 10.514
69 11.274 10.985 10.670
70 11.433 11.145 10.832
71 11.592 11.304 10.988
72 11.752 11.463 11.151
73 11.911 11.622 11.306
74 12.070 11.781 11.468
75 12.229 11.940 11.625
76 12.389 12.099 11.786
77 12.548 12.258 11.943
78 12.707 12.417 12.105
79 12.866 12.576 12.261
80 13.026 12.736 12.423

My Meteor Snowblower has 80 pitch, 32 teeth, 10.75" OD. Are you certain the dimension the bottom of the teeth isn't 1" (80 pitch)?

I will double check again tomorrow and take a picture of it if I can figure out how to attach it and go from there.

Can you not just order the sprocket as used in the kit from Northern?

I called northern tool to try to get some information. They said it is a drop ship item so they never actually see it so they referred me to Braber equipment. I called Braber and was on the phone with the guy for a half hour. He said the only thing he can see for information is just the entire kit which is $629. + $25 for shipping. I even played stupid and told him that I had bought the kit and I had a broken tooth on the sprocket so I wanted to replace it instead of dropping 650 bucks on an entire package again but he could not help or see anything on his computer that would help me.

Are you 100% certain the chute gear is not 80 roller chain pitch?

If yes, this would work.

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.

I'm guessing that you tried McMaster-Carr. That's where I go first for any mechanical parts.

What is the center to center dimension at he BOTTOM of the teeth?
