Good morning light speed. What you have photographed is perfectly normal and can bee seen at most inspections regardless of mileage but that is not to say good or any indication of long life of the rubbers. You should think of those rubbers as being like a tyre (tire) It will wear out progressively, shedding dust and minor particles till the fabric of the rubber becomes distressed and starts to break up. The failure is then rapid and the only warning is when you see chunks of rubber falling out of the hole in the bell housing. Some unfortunate people don't have the hole and so failure comes as a complete surprise. I have recently been experimenting with silicone grease on the rubbers and this does seem to help - thanks to those of my customers who are trialling this for me. the problem is getting the grease in there without access through the bell housing - a hole cut at the back of the bell housing and some fiddling with nylon tube perhaps????

Having had years of experience with this type of coupling in the Marine Industry - when Morgan introduced the Centa I did ask on this forum whether anyone had questioned it's projected service life and the ease (or otherwise) of changing the rubber element when the time inevitably came.
I don't recall getting much, if any, response.
I feel sympathy for M3W owners who were made to pay for the privilege of having their original defective compensator "upgraded" to a Centa and are now realising that they'll be faced with another large bill when the Centa requires maintenance or modification.
Someone, somewhere within the MMC needs to go back to college and learn some engineering basics.
You have brought up the example of what happens when a dynasty controls things. If a team of internationally educated engineers had worked on the problem they would have concluded that the Liberty Ace , the very patent that they purchased, was the way to do it. Shaft drive worked great for it.

Not so great for the passenger though! The angled shaft meant they had to have a really small bum.

Clicked over 10000km last week and because off this thread had a look and a feel around the Centa. No sign of anything amiss, no chunks or shavings like above. Phew.

Hi Phil, Thanks for your great support and thoughts. Do you mean with the above solution to "lubricate" the Centa rollers with silicone grease ? I have on both the cars the inspection hole (which I made even a bit wider to get better access for inspection). But how to get the grease so much in that the whole roller has grease on it ? It looks to me that if only the rearward part of the roller is "greased" and the forward part not it will make torsion on the roller even worse. My other thought was also to make a kind of tray made from mesh under the inspection hole. In that case it's easy to see if the rollers are breaking up because you don't loose the chuncks through the hole. But ... if i would live closer to you I would let made your upgrade on both cars.
