My 1998 MTD's auger on the chute side stopped working the other day... I can spin it by hand... Is it a gear box issue or a sheer pin? The other side works fine. It may have tried to throw a rock... certainly was a wet heavy snow that day. I haven't had time to take a look at it yet...been busy at work but want to try to take care of it before the next storm 馃槥

Welcome to.SBF

It sure sounds like a sheer pin. Look and see if the sheer pin is there. If the one side is functioning it more than likely is the sheer pin. Two minute job to diagnose and repair. You may have.to drive the broken pin out with a punch or other tool.
Let us know what you find.

Donner,


This should be a pretty easy one to diagnose. :icon_scratch:



Like Micah' suggested, my money would be on the side of it's only a shear bolt that has broken, especially if only one side of the auger assembly if free wheeling.
But you need to look at the drive axle that comes out of the gear box. Usually, the tubular part of the auger is short enough that it doesn't reach all the way to the sides of the auger box, leaving a small part of the axle exposed. If you can spin that auger and can see that axle remains stationary, then it's just a shear bolt. :yahoo:



If there's a broken one, like Micah' suggested, you'll have to drive it out of the axle with something, because usually you're not lucky enough to have the thing just fall out. I like to use a hammer and a big nail set. It should pop out quite easily.


Don't cheat though, and put a regular bolt through there like some folks have done. Make sure it's a shear type rated for your machine. Those shear bolts are like insurance. They prevent more serious and much more expensive damage from occurring to your machine, should you accidentally hit a solid object hidden in the snow.


:thumbsup:Good luck!

Thanks you guys...it was the sheer pin & tapped out pretty easily. Looks like it ate some dirt in the heavy wet snow at the base of my driveway, so dropped the shoes down to try to keep it from happening again real soon.

Dirt doesn't usually cause a sheer pin to break. Possible, I guess, but unlikely.

It may have tried to take in some larger rocks as well and most of it's part are original and rusted. We will see how it goes at the next storm.
