Friction ring issues

I have an Ariens model 921032 snowblower. We had the friction ring replaced before the season started to be ready. Right! Well we have used the snowblower about 3 or 4 times and the friction ring is shot. What would cause this to happen?

Could be a bad quality to begin with, possibly misaligned, or something in its path intruding into it?

Pretty hard to tell without inspecting it?

Could have been installed poorly even? I would contact whoever did the work.

The engagement cable could also be mis-adjusted, applying to much force or not enough.

You say that the friction ring is shot. Please describe the symptoms you are experiencing. Have you removed the belly pan and inspected the friction ring? It is unusual for a friction ring to fail so quickly. If it's not the friction ring, the problem could be a loose drive belt or an adjustment of the drive control linkage/cable.

Yes I did remove the belly pan and inspected the friction ring. Now rubber left! Lots of black powdery stuff on belly pan. The machine would only move a couple little jolts then nothing, both in forward and reverse. It was working fine snow blowing for like 2 hours then it started the little jolts and really never moved forward much. I managed to get it in the garage and then removed the belly pan a couple days later to find the issues. I did talk to my son who is an engineer and he said it is a very poor design plan.

The Friction Disc design has been around for years, and is a very effective drive system, as many manufacturers can attest to, as well as customers/owners of these units.

I would tend to lead to an improper install/adjustment, something broke, or I have also seen inferior discs that have disintegrated.

The disc that the friction ring contacts should be smooth and clean, it may have been damaged when the last ring failed. Keep the friction ring and the drive disc clean. Also, how are you shifting gears? It's not good practice to shift on-the-fly, the machine should be stopped, then the gear changed. Shifting on-the-fly can cause rapid wear of the friction ring. Move the gear selector through the gears and check for anything in the transmission that might come into contact with the friction ring. Check that the gear selector is properly adjusted. The operator's manual will have the procedure for adjusting the drive belt tension, the drive control lever tension and the gear selector. If you don't have a manual, you can download one here,

If everything checks out, order another friction ring directly from Ariens so you are sure you are getting a genuine Ariens part and install it yourself. The installation procedure is in the manual.

That, and make sure the drive clutch cable/linkage is correctly adjusted. If not, the disc may slip, overheat, and disintegrate.

I had some trouble with a split ariens blower in the '70s, or '80s with the rubber drive ring peeling off. Replaced it 2,or 3 times. It was my father's. As I look back, I think the rubber vulcanized ring may have been been adjusted too tight, also in those days the "clutch was always on, and to stop it had to be squeezed to stop the machine. They are safer now. They have dead man clutches now.
