Excessive cush drive wear

How long do these last ?
Mine has done less than 5000 miles and it has alot of play,

I removed the 'silent blocs' from the cush drive assembly and refitted to the sprocket flange. This then shows alot of play between the sprocket flange and the cushdrive assembly.

Each 'silent bloc' also wobbles about in the housing of the sprocket flange.

I'm guessing I will have to now replace the whole assemby.

Any idea why this has happemd in so few miles ?

Cheers
Adam

I've recently been cleaning & servicing a 2008 F4.
33,000 kilometres and the cush drives are still as new and snug.

It ain't what you ride, it's the way you ride it.

I did have an issue with a hub that failed giving alot of play on the wheel, all I can think is that this may not have helped ?

The hub was replaced about 1000 miles ago and has been fine since.

Adam;
yes, on the early bikes (750s) the silent blocks pressed into the sprocket
your bike has a flat sprocket and what is called a QC carrier, the silent blocks press into the carrier
the 3rd version is '10+ Jap paddle style cush grive

if your silent blocks are loose in the carrier, its not good, probably damage from the hub failure

i doubt its the silent blocks, they have steel housings, its probably just the carrier

watch Ebay they are usually ~100 quid for the whole assembly.....i bet the dealer wants double for just the carrier

no nuts or bolts
no silent blocks
or the hub

If it was the hub that caused this I wish I had left the bloody thing alone in the first place, would have saved myself the best part of £1000

Looks like worse case I need 27,37 and maybe a set of 30, Total about £400 new

Do you think the wear might just be in #37.

Guess I'm off the road at the wrong time of the year now

Cheers
Adam
