Cush Drive Replacement? (Ducati 600ss)

**Dan** · 18 Jul 08, 06:36 AM

In the attached picture you'll see that the bottom 'cush drive' rubber has displaced from it's metal housing and moved back into the wheel. Now I can get in behind the drive and knock it back into place but I'm sure you'll agree that this isn't adequate for a long term fix because the rubber will just move again.

So as far as replacing cush drives goes..... should I assume it's best to replace all six on the rear wheel of my 600ss race bike, or would any of you say that just replacing the failed drive is good enough. Also, how the hell do you get them out and and then back in properly?

Dan I am no mechanic and to prove that ... thx to you I now know what they are on about when talking about Cush Drive.
It looks like the place where sprocket is attached? If so shouldn't there be something holding those rubbers in place?

The cush drive rubbers have an inner and an outer mild steel sleeve to which the rubbers are bonded. On Dan's bike the bonding has let go between the rubber and the outer sleeve allowing the rest of the bushing to slip in towards the wheel. You could try superglueing it back in place but I suspect it would let go again pretty soon.
It would probably be best to replace all the rubbers but you'd probably get away with the just the one if the others are in good shape - they are a bugger to replace I believe, I've never had the pleasure.
You'll need to find a drift which is a marginally smaller diameter than the bushings but fits comfortably on the outer sleeve, an old socket maybe. If there is a shoulder on the inside you'll need to knock them out from the back which will probably be very difficult. If there's not then it might be easier to knock them right through. Best of luck.

You need a a couple of tubes and a draw bolt to pull them out.
To be honest its not that bad and the loading is shared. Its not suddenly going to let go.

It will do the last 2 races.

Now I am stayin in front in case it comes off and hits me.

Good luck getting them too Dan, they come in packs of 5 at £130 plus VAT, your not able to buy them individually either, so you will need 2 packs..

...this is what i was told

I had a bit of grief with mine on the 996 recently, superglue, loctite and a careful inspection every trip out is holding up for now. They are a piece of 5hit design in many ways, and cause lots of damage. I meant to try BSL or any other power transmission distributor for a pattern part, they'll probably be an industrial part of standard dimensions anyway?

Thanks everybody..... I think I'll try some super glue for the moment.

Ollie, I thought that when I last visited my nearest dealer they said I could buy a single Cush Drive for about £12, I could be wrong though and the dealership isn't the best in the world.

Luca, I've attached another couple of pics from my 748 to extend your Cush Drive education. These pictures were taken when I changed my rear sprocket and added a sprocket carrier.
