Hi Everyone,

I have an Ariens 11528, Model 924125 Snowblower. The connection between the blower and the main drive unit is no longer stable. I'm not sure what happened, but the holes for the bolts that secure the blower to the main drive unit are larger than the holes. So what's happening is the blower is separating at the top slightly. When the bolts are in the center of the hole, everything works find, but when vibrations causes things to shift, the gears misalign and the belt to come off.

Has anyone else run into this? Right now, I'm thinking of bolting a steel angle bracket to the top off the main drive unit and then bolt it to the blower unit so it doesn't flex anymore. Thoughts/Suggestions?

Appreciate the help.

Thanks - Dan

I don't have that blower, so take this with a grain of salt. Something on that order on a vehicle - enlarged hole. I took some 1/4" plate, drilled the correct size hole and bolted it together properly aligned using longer bolts. Having previously ground it down to bare metal, welded the plates on. You could also weld up the hole and redrill it, but unless you're a purist, I think the previous may be the simplest solution.


In my case it was a shock absorber mount, but once fixed it went another 5-7 years without a problem.


Good luck.

Thank you so much. While I don't have the capability to weld plates on, I'm sure I can find a way to mount the 1/4" plate with the correct size drill hole aligned over the hole. A much better idea that what I was thinking.

Maybe align a plate then drill through it in a few spots and tap the holes and screw them together? Or get it together and take it to a machine shop and have them weld it for you. I don't think it would cost that much to do a little welding for you.

I wanted to provide a picture of what’s going on before I try my own patch. Has anyone run into the bolt holes for the blower attachment are worn and now larger causing the belts to misalign? How did you fix?

There isnt anything wrong with those holes tighten the bolts more or get new bolts


The issue is the holes have become much larger than the bolts due to wear. When the bolts are touching the side of the hole, the gear pulleys are not aligned and the belt falls off.

I tried new bolts, same issue. What’s happening is as the snowblower vinbrates, the connection slides because the hole has stretched. If you zoom the picture, you can see the hole is much larger compared to the day I bought the machine.

you can see where the bot heads are way outside the holes
again you can blame that if yoy want thats not why
the holes are bigger by design
they shoudnt loosen the machine shoudnt vibrate enough to loosen
maybe the female part is worn oryou dont the right bolts with the knubs that act like a lock washer
its not the bolt holes carry on

I have no idea how it bolts up but could you use a flanged bushing with an ID that matches bolt and dremel hole a bit to perfectly fit the OD of the bushing. That assumes that the flange can be accommodated.

I have the Ariens 924108 model that I am working on currently, although your machine looks a bit older than mine.

1) Bolt tightening does not do the trick?

2) Maybe use a serrated flange bolt for better grip than a standard bolt?

3) Worst case is to enlarge the holes and put a thin spacer around the bolt so the chassis/bucket position is held true.

4) Alternatively, will a washer fit in the gap under the the chassis metal to make a tighter fit (see picture)
