Outdoor Power Equipment and Small Engines - Toro 521 Snowthrower, model 38052

Started clearing off results of our latest snow storm this morning with my Toro 521 Snowthrower. Snow was very heavy and wet. Snowthrower is a 5hp and seemed to work ok at first as long as I didn't push it. After awhile the main, or primary auger, (on the left side from the operators position) stopped turning. The other auger seems to work ok.
I can turn the auger that stopped working by hand, it doesn't feel like it is attached to any gears....does this sound like a sheer-pin or something equivalent? If so, is it a difficult job to replace?
I can use all the help I can get.....thanks, John

It definately sounds like you broke a shear bolt. If you look at the auger in question you will see a spot for a (possibly 5/16-18) bolt to go through. If it sheared completly you may have to use a punch to knock the rest of the bolt out of the auger shaft. Spin the auger shaft around to where the bolt used to go and you may see where the hole is.
Before you so this, remove the spark plug wire from the plug.

Thanks Snoman, I will follow your good advice.

jmel, how'd you make out? I know this is a tricky shear bolt to replace due the drum style collector. I've had instances, on these units, where I've had to remove the end frame of the auger housing to access the bolt.
