Which way does The tapered shim that goes against the motor which is smooth on one go. What holds the motor in place. Is it just the half circle camp and this shim?

Be really careful doing that it's really not meant for the average Joe to change.
Here's an instructional video hope it helps.

Smooth to outside of motor or body of the vacuum? Where can I download a manual.

I have the Owners manual you posted and watched all the YouTube videos I found on the S7210. The owner’s manual for this vacuum doesn’t show the belt and in the Youtube videos I can’t tell which side they are installing it. I found a parts diagram but it is not clear enough to determine which side you are seeing. I have searched for a repair manual and found one web site that listed it but can't down load it.

@kris_loehr my video is probably the best you're going to get.
It is not intended for the user or for anybody but an authorized dealer to do.
This is how most premium brands operate. You're not going to find the service material out in the open there would be legal ramifications for it from Miele.
This is part of the dealer contract that is signed.
I've gotten a lot of flack for even showing it on video from other vacuum dealers.
as stated before I would recommend that you bring it to an authorized dealer or collector who works for an authorized dealer.

I just need to know if the wedge for the motor is smooth side to touch the motor or the housing. My background is dealership mechanic for Honda, Volkswagen and Mercedes. It is not as hard as timing belts I have done on cars. I appreciate your help.
I remember asking myself this question when I performed the repair on my own (former) S7. From what I remember, there is a matching rough surface on the vac which meets with the rough surface on the wedge.
If you post a picture to jog my memory, I can probably help you even better.
Good luck!

I will post a photo. I assembled it with the rough sides touching but just wanted to make sure.

This is out of my league.
I'll tell you my dumb down guess.
The flat part of the belt or ribbed part of the belt. Ribbed if it gets bumped and it's cut. If soft side hits possible Nick.
I don't even know if it helps.
Have you put belt on and turned the shaft to see how the belt flows. This usually gives you a good idea.
I also get you don't want to do it twice.

You are thinking i am asking about the belt that connects the brushes to the motor. I am good with that. The motor drive end and the brushes have teeth so I know it is smooth side out and now understand your other post meaning. The motor goes into the housing and is uses a half circle clamp at one end and a wedge like they use to expand an axe handle or hammer handle. The wedge is smooth on one side and has tiny serrations cut into the other side. The place the wedge goes into has the same tiny serrations on the housing side and the motor is close to being smooth where the wedge would touch. I was not aware of the wedge until pulling the motor out to replace the belt. I thought I had done the hard part in replacing the broken lower motor housing and back wheels which I found timing them very similar to a timing chain on a car, The gears have one thick tooth and a matching larger notch on the other. With the handle section removed and cover off you can check that the gear mesh with the thick tooth and one larger notch.
One video mentions timing the belt. That would mean you would have to have the sprocket on the motor and roller brush at a certain point when installed. That seems impossible and serves no purpose.

Yep, timing the retraction mechanism for the rear wheels is the other challenge. You’ve already discovered the key, though. Big tooth in big valley. If you can get that squared away, the rest is cake.
There is no need to time the belt, only the rear wheel retraction mechanism.

Miele repair verified what broomvac thought on the wedge being smooth side to motor and rough side to rough side. I also asked what holds the motor in place other than the wedge and half circle clamp. He said the brush cover plate which I missed.. I appreciate everyone’s help.
