Cush drive replacement necessary?

[axle167]

Hi all,

I received a new set of carrier, sprockets and chain to replace my stock ones on my 07 s4rs with 24,000 miles.

Took that to my local shop for install and they advise me that I'll also need to change the Cush drive as part of the carrier change.

The carrier I got is a super lite PCD2 from sprocket centre.

I don't remember reading that anywhere. Is that really the case?

Thanks!

Does the carrier have a lip or ridge to retain the outer rings of the cush drives?

Occasionally the seperate from the rubber and migrate in to maul the eccentric.

Perhaps some of those have seperated or they're being conservative.

The new superlite carrier does have lip for the back out issue of the cush drives.

I asked the shop about their condition and they said that it should be replaced as part of the service.

I understand if the bolt separated or the rubber is cracked, then I should replace them, but I'm not sure about doing them as a precaution.

btw, what's the difference between the superlite PCD1 and PCD2 carrier. Different website list different part for my bike.

PCD2 for an S4RS (and some other models)

FWIW, my little bike uses a PCD1 and I know it's different - if I remember correctly one does not fit the other.
The width is different...

Did you have to change your Cush drive?

What was the mileage in them?

I mounted the quick change system somewhere arond 50-60,000 km. The cush drives were fine, but I changed them anyway.

I'm on my third sprocket (second change) and have had no issues. I'm at about 17,500 miles.

Mine failed and ate away half my hub eccentric at 25k. I'd replace them.

I've got two thoughts and each leans to the opposite solution.

Thought one is what I'd do for myself and for my own bike. New carrier has retaining lips, so IDGAF if the cush fails, the eccentric-damaging outer steel shell is retained and I get to keep on This is what I did for my 1996 916 that I put ~30k miles on. Afam carrier went on near 10k miles, transferred the cushes, rode a whole lot then sold the bike around 40k miles.

Thought two: how much are the cushes? It won't hurt to follow the technician's advice and have new parts on your bike. (keep the old ones, just because). Then should anything go wrong with the installation and parts you've got, you can remind the technician that you spent extra money on their advice to make the installation more reliable. Saying this makes me but that's life and it is what it is.

as per Ducati Shop/Service Manuals, it should be replaced on 'every chain/sprocket replacement procedure'

Thanks for all who replied.

The shop advised that they would only replace the rubber part of the cush drives for $60 as the bolts are still good .

I thought I needed to replace the bolts along with the rubber piece as an assembly.  Parts in Canada can be damn expensive.

but for $60, I'll just bite the bullet.
