B2781A snowblower Hub/Sprocket bolt sheared

[kevinj]

O.k., I understand how yours goes together now. I am still curious as to why those bolts sheared instead of the shear bolts intended for that purpose? It sounds like you are back in business for now? John

The bolts sheared because they were loose. As stated above the tapers draw together and transmit the torque. One can search for QD bushing and read more on the Woods, Martin, Dodge, Browning sites.

Without taking the hub off I was able to back the two sheared bolts out.

When I put two new bolts in how close should the hub get to the sprocket?

The large sprocket seems to have a little forward and back motion to it, along the main shaft.

Thanks,
John

Sooooooooo.................did you get it repaired?

Thanks for all the replies.
I was able to use the little snowblower to make a path to the road, 1/4 mile dirt drive, and get to the hardware store first thing in the morning. Got the 2 grade 8 bolts in and tightened up and fired it up and it was fine.

I was a little nervous but Kevin's explanation of the hub and how friction held it to the sprocket helped.

Got a call from the dealer today to check with me.

Seems like it is running fine.

Thanks again,
John
