Cush Drive rubber in rear hub - .: XT660.com

Hi
I think there has been discussion about cush drive rubbers in here somewhere but can's see it now. However please see pic below of mine. These have completed about 7500 miles. Yamaha dealer said he would look at them tomorrow and put in warranty claim but then I would have to wait until Wednesday to get the new parts so wont have bike to ride to work Mon,tues and weds. Should I put back the worn ones or wait?

Any advice will be welcome.
thanks

hi ya, had mine out recently,they dont look unlike yours condition wise,are yours clunky? if not you could ride away until the new ones arrive. make sure the bearing on the carrier/sprocket side is in good nick. mine also was wearing a little between the carrier and wheel,a smidge of grease was added to help to let it move back and forth more freely

hope this helps

Thanks for your reply.

I never noticed any "clunkyness" prior to taking the wheel out to get the tyre changed.

I go to see the local dealer tomorrow and will try the warranty angle and hopefully bring the old ones back and re-fit and wait for a few days until the new ones come. Can you believe it that I was told by dealer that Yamaha UK wont send out parts on a next day service and it takes 2/3 days! what happened to customer service- I sell spare parts and my customers would not put up with this type of attitude from Yamaha.

I will check the bearing also.

thanks.

Can you only get the drive rubbers from Yamaha or is there an alternative?

Price from Yamaha dealer quoted today was around �26.00.

Hey Stridey,

No alternative that i'm aware of.

I would strongly recommend that you put your foot down (politley) with your dealer and insist that the rubbers are replaced under warranty. As far as i know replacement of the rubbers is not mentioned anywhere in the service shedule or handbook, so they shouldn't be classed as a 'wear&tear' part. I recenty had my rubbers replaced under warranty along with the sprocket bearing (and starter motor, different story tho) and the dealer didn't quibble at all. If your dealer wont budge, maybe try a different one?

Fitted new cush drive rubbers last night alongwith new Avon Gripster tyre and wow what a difference. Now smooth acceleration when coming on/off the throttle-no jerking from the drive.

I got mine replaced under warranty FOC but was quoted �26.00 for a set of four rubbers.

Surely we cant acccept that every 5-6 thousand miles we should have to change?

Could someone find a rubber maker to make some better ones?

I see the original Yam ones are made in China- low price to Yamaha and crap quality!

What about a KEV mod/manufacture and made available to everyone on XT.660.com?

Mine were replaced at 10.000km under warranty and I got a 3-year warranty, so they will be replaced as long as the warranty is on. Otherwise pay the few bucks to replace them, no big deal, it's a thumper, ya know! My dealer has overnight service from YamahaNL: today ordered, next day delivery, good thang!

Your luckier in The Netherlands as we in UK only get 2 years warranty and my dealer says he can only get parts delivered to him two days from order!

Hopefully if Yamaha get all these warranty claims they will do something about it by making better quality rubbers but probably not as cost price to them will be cheap.

I suppose we just have to look at it as everytime we change a tyre we have to buy new drive rubber set

Lets see what happens over the next few months!

There is a a Kev mod already for this problem I did mine this past Monday after getting a puncture. You only get around 5000 miles out of a new set of rubbers they become compressed then start to break up, the excess movement allows the rubber to twist & this causes them to break up, the sprocket carrier then has lots of free play, which makes the bike surge & feel snatchy at low speeds. Once they have become compressed they don't really shrink much more, so the free play needs to be taken up.

My fix is very simple, I have never needed to replace the dampening rubbers on any of my XT's even with my last XT doing over 20K miles.

If the rubbers are in tacked & not breaking up you can take up the free play using a inner tube rubber strips. By cutting 4 strips & laying them over the dampener rubbers then push the sprocket carrier into the wheel hub, this will fold the rubber strips in half & rap them around the sprocket holder & between the rubbers. You cut each rubber strips to size so they can rap over the sprocket carrier to size. You can use different thickness rubber tubes or double them up to take up the free play, go to a bike shop & get an old inner tube from them. You want the rubber strips tight, you need to apply alot of pressure to get the sprocket holder to into the wheel hub, using both hands push like hell on the sprocket from side to side & the rubbers will fold in half & slip between the rubbers & go together. Do not use any lube to get it together, the lube will damage the rubbers.

I would recommend one to do it around 3500 miles so the rubbers are still in good condition & you will never need to replace them & you will always have a tight sprocket Holder.

Thats a good tip.
