Marko did you order the OptiBelts from Fanatec? If not can you provide a link for others in case they need them? What were the costs? Thanks.
Wow I just broke my old lap record in a FM4 effort by two seconds might have to try for a leaderboard result on my own account. More control with less distress at vital times due to steering response and a bit due to better braking via modified CSP V2s.
I am toying with the idea of making an ultra-low inertia wheel. I can modify one of my CSR GT style rims pretty easily. See all the mass low in the wheel? That can be reduced, or a Formula rim conversion performed. I will try some driving with more mass attached to my CSR-E wheel too.
Hey eK, I'll be dropping Fanatec a line tomorrow re the small pulley bearings being loose. If we have two confirmed cases in the small sample size of those following this thread, then there must be many more.
Hint…those are the weights I use on my 10x stronger ABS motors on my CSP V2 pedals…which actually shakes my CSL seat framing fairly well. The stock ABS motors are more of a "Marketing Feature" as they are too weak IMO. Basically the stockers are the same motors used in an XBox or PS hand controller for direct finger vibes. And the same motors are used in Fanatec steering wheels (except two instead of one)…those live in those squarish holes you see in the aluminum plates at 3:00 and 9:00. My ABS vibes are now so strong that even I chose to add an adjustable attenuator…which lives ahead of my temporary converted-from-sequential e-brake…see pic in my CSL seat image below: "ABS":
Looking at the optibelt product description, it seems that PJ is a code for Height ( thickness) of the belt, 3,5 mm. optibelt.de
Why not order a PH, 2,5 mm, instead of grinding the thicker belt?
If the perfect thickness, is not available, since the stock belts are about 10 $, a custom thinner, might not be that expensive to order.
Here is my small update.
I went down from around 450g drag to about 150-170g ( measured on Bmw-heavy rim )
I did a water break-in as motors just wouldnt stop squealing, after that they are fine
Don't know why they didn't put thermal paste on the outer sheel between sleve and motor as they did on the aluminium fins that goes on top of it ?(doesn't make sense to conduct heat from one part that is not properly connected to the heat source at the first place )
The loctite on the small bearing is dry now, and the bearing is securely in it's place ( like it should be )
Longer(motor) belt is fine, I have grinded it on the top to 2 layer of fabrics, it feels almost like a rope now, and it don't slip at ridiculous low level of tension, great
Maybe I should try to grind it on the rib side, since the slip is not the problem here.
Now the problem is with smaller belt as it's slipping at the pulley. Maybe it's because of the small belt being little longer that Gates 414 vs 408 ? or something else ?
Belt and the pulley are clean as clean it can be.
Any suggestions ?
