Hi Anyone seen this before? I noticed metal splitters on my rear wheel. After checking I saw that there are three metal rings from the rubbers attached to the rear chain wheel have come out and scrape the exentric tensioner :-/ What's the problem here? Why do they come out? To old, time to change I suppose..?
Looks like your cush drive rubbers have perished and backed out catching on your eccentric hub adjuster. A Renthal sprocket carrier will stop this happening as it has a lip on the rear to prevent them from backing out. Steve
As above, a common problem and it can result in a new hub eccentric. A quick change sprocket carrier will prevent it happening again but in the mean time you will need to look at replacing the cush drive rubbers and also examining the damage to the hub. This may necessitate a new hub if it is really bad. They show up on eBay from time to time.
I've seen worse. It hasn't gone all the way through and milled the swing arm. There looks to be sufficient thickness remaining to allow you to adjust the eccentric.
I'd say up to a point you got away with that in time. Not ideal if you want a pristine bike but liveable. Good luck
Thanks guys I will search for a pic from how it was on the internet and then decide what I do with it...
If you go for a Renthal or jt carrier you will need a new sprocket to fit. This is an old thread relating to the same problem. https://www.ducatiforum.co.uk/threads/996-hub-trashed-by-cush-drive.23773/ Steve
I'm sure as has been said by Ricky that yours will be OK as it looks like there's plenty of meat left for adjustment. Steve
Indeed, mine was much worse and I carried on using it for a couple of years before I got a replacement. As long as there's enough to hold it together and get the adjuster on it will be OK.
Could have been a lot worse. I picked up an afam sprocket carrier for a decent price 2nd hand just to avoid this. Also, looks like your eccentric is in the wrong position from the picture? Ian
If I were a betting man, I reckon it was moved to the furthest forward position to facilitate chain removal.
