Friction disc drive problem

I am working on a newer Ariens machine. The machine would not roll at all. I went thru the whole drive system and I think I may have found the problem. Is the steel disc that the rubber roller wheel rides on supposed to move back and forth? It looks like that bolt and roller is meant to slide inside the assembly. It took the disc off the housing and it seems to be ok but that inner sleeve does not move. I would take the bearings out to check it , but I am not sure how to remove them.

What machine your working on would be helpful. When you pull the lever to engage the drive the rubber friction disc should make contact with the metal friction disk. Are you sure the rubber friction wheel is not worn out? I recently replaced one but I honestly thought that the rubber looked good but someone more knowledgeable than me pointed out it was worn out. Sure enough replacing it fixed the problem. Good luck.

either the rubber wheel moves to make contact w/disk or disk moves to make contact w/rubber wheel, depends which model you have and/or age of machine. pics would help.
engage the drive lever and see what moves if anything

No, the rubber looks fine. It is actually pressing on it so tight that it wont move.

with engine running prop up rear of machine with tires off the ground, belly off so u can see the drive parts, does drive disk turn? engage drive lever, does rubber friction wheel turn against the drive disk?

Sounds Like a Drive Belt Issue if Friction Wheel is Making Contact.

If yours is an ST824 than the friction wheel should back away from the drive plate with the handle released. It's the friction wheel that pivots onto and off of the drive plate on that model. I used 924100

Can you start it or does it feel like it's "in gear" when you try to start it and won't roll even when you have it in neutral not running ??

I'm going to give you an idea of what you should be looking for. What I wrote below may not apply to your Ariens but I'm sure you can pick up some ideas what to do and what to look for.

What no one stated, the round disk or plate moves up and down to make contact with the rubber disk. The plate engages the rubber disk. The rubber disk moves left to right, and right to left, when you shift gears. The location of the rubber disk on the plate determines what gear you are in.

Lift up the handles putting the snowblower on the front or face of the auger housing. Remove the bottom plate, there should be for screws, two of them you may need to only loosen, the other two you need to remove. Then turn the wheels, you'll see what's moving; shift the gears, you'll see the rubber disk moving; press the drive lever, you'll see the plate move up and down.

But as Jack Mel's mentioned, check the drive belt from the top to see if it's engaging. Squeeze the lever, turn the wheels, you'll now see everything.
