What symptoms are you seeing with your motor?
BreakNDish, why don't you ask your questions in the post and that way anybody else in a similar situation can benefit from the Qs&As. I am fine with slightly OT stuff as long as it's still on the subject of modding.
I've made some progress on my water cooling, check these puppies out:

It's not real clear in the vid what kind of belt you have. Is it a cogged (synchronous) belt or a poly-v belt? I don't think a poly-v belt would work unless you changed the way the wheel's position is reported. It appears that the motor has an encoder on the shaft that reports position. This means if the belt slips you have no way of keeping the wheel aligned, so I hope you're using a synchronous belt. Can you see any numbers on the motor can or flux ring? Like 540, 550, etc? If not can you measure the diameter and length of the motor can? If you have one of these sizes there are a lot of replacement motors available. There are a lot of options really if you're modifying. What are your plans to get more power to the motor?
Hmm I've been digging through the Johnson Motor website and can't find anything with those numbers. Can you pull the flux ring and check under it? It's a 24V motor right? And about how old is the wheel? The website may not have anything if its too old.
Well, why don't you try running it as-is, but with more power. Johnson motors look to be pretty decent quality. What is you end goal? More torque? More wheel speed? The green wire sounds like a ground wire. When I saw it in the vid (hard to see the specifics, never got a really clear shot to see if there was an encoder) I thought it was an encoder signal wire!
Motor PNs, if present, tend to be on the flux sleeve on cheap "can" motors. Custom motors made for a device may not have them.
You can physically fit many different motors onto sim wheels using such drives. But you really want to have low cogging, low friction, and the ability to hit full stall without running into PSU or H-Bridge limits.
By cogging I mean the little pulses you can feel when you turn an uninstalled motor by hand. This is due to varying magnetic forces between the magnets and the steel armature plates. Fana-Buchis™ have basically no cogging of this kind.
By friction I mean the drag when you turn the shaft, which is related to the bearings and brushes. The bearing friction rises with side loading, and some shafts can bend since most can motors use 3 mm / ⅛ inch steel shafts. Side loading increases under FFB load.
If you measure the terminal resistance of your motor (which should be done with it a bit warmed up) you'll get a sense of about where you want to wind up. This is a bit tricky to accomplish since it can vary a bit due to the brush/commutator resistance when not moving, however you can still get a sense of it. Suppose your motor was say 10 ohms. You really don't want to drop in a 0.1 ohm motor.
There is much, much more to it but those are some of the points.
Fish scale it, and try WheelCheck or viddies for some baselines. Then mod and retest.
I can get well over 20 pounds at the rim without extreme settings or heat woes and with less load per motor than stock. More if I crank it. This can be a lot of fun in rally. Since you can get an extreme force one way and then the other and then back. So there is a >40 pound difference between the directions which your hands and arms feel.
It sounds like you do have a damaged commutator. RacerXX's method of redoing the water break-in could possibly bring it back, you should at least try it. Replacing the motor should be cheap and easy, but Fanatec can be difficult to get parts from out of warranty sometimes for some reason. You might be able to change to a slightly different motor with the same size and characteristics if you do some looking.
At a certain point I think it is fair to keep something to one's self. I have made innovations in music, the details of which I would never share publicly. You will get no grief from me RXX.Haha, I think it's more that they feel like they're being teased and taunted rather than not being aware or preferring not to realize that there are better ways to reach goals. But maybe I'm wrong. It might be better to give everyone a general idea of what you've discovered than to say, "I found something that works great for this problem everyone's having, but I'm not going to share it." I think most are looking to share info here and some maybe feel like you're a bit evasive with certain answers, lol. At least that's the way it looks to me by some of their responses and PMs.
Had quite a breakthrough RE Heat Management. Now I can do it in a much simpler manner with less complexity. But I will keep that under my hat for now, gotta test lots more. Found some things to do that are brandie new, never done before by anyone. How's that for cryptic?

I'm not selling anything or whatever. Just using some of my skills and creativity on my hobby. If I share viddies / pics of my latest solution it won't be for at least two months. Some would rather hear nothing at all until a final released product comes out complete with a web store and a large quantity in stock. I'm not doing that I am just sharing some of my messing around. I had an excellent breakthrough but many variations and more testing is needed. That can take some time, and when I get busy on my main work it will take longer.
If you have created things, my POV will tend to make more sense. I don't know whether you create or innovate. If you do, it is fine with me if you talk about it, or don't.
Hey some of my favorite musicians are in the recording studio now I hear. Why the H are they not live streaming all of this? Their new music won't be out until maybe this Fall. Get my point?
