Just loosen the rear axle bolts, but you may even be able to get it off without doing that to be fair. I managed it on my fire damaged one as at the time the rear wheel was stuck solid and the axle bolts weren't having any of it Tongue

I went to Loughborough Yamaha today to get the replacement front sprocket nut.
It was only 9mm so I didn't buy it. They insisted this is the current one but knew nothing of the saga.
Any ideas?

Make sure and quote the part number of the new one to make sure and get the right one.  Wink

Chris

Edit: Part number for new 12mm nut + washer is 90891-10124

I would've told them to make a bloody effort to find out and do their job!
Give Fowlers of Bristol a ring and order it from them, they'll ask you for your chassis number so have it ready, it's on the frame at the front of the tank.
I haven't got the part number to hand but it's on this forum so do a search for the correct part number.

Re: The front sprocket nut and washer saga - darrsi - 26-04-13

Yeah that's the jobbie, sorry i was using my phone earlier otherwise i would've searched for the part number, but do not accept any other number than 90891-10124

Re: The front sprocket nut and washer saga - Dead Eye - 26-04-13

Its also available from Wemoto - purchased this myself so can confirm that it is most definitely the 12mm nut Smile

Loughborough yammaha fitted new nut and washer for me few months back . It was at my request and I supplied my own part which I got from wemoto. they didn't seem very clear on the issue and said it wasn't necessary , but did fit new one without too much complaint when asked and part provided.

Re: The front sprocket nut and washer saga - andybesy - 27-04-13

Oh and if you have the google-fu I was eventually able to find a pdf copy of the yammaha service bulletin, technically it was for early fz6 models but same issue, had print out at ready but not needed in the end

Can't fault the service that I have received from CMC. 
I would advise anybody to contact their dealer and mention the inspection notice to service before buying the parts.


Ditto.  My 2002 Fazer 600, not dealer serviced since 2004, CMC Clay Cross did it FOC with no quibbles at all.  This was about September 2012.  Even got a free coffee in the cafe while waiting!

They *look* like the new type to me, but doesn't hurt to get a proper dealer to take a peek at it.

Re: The front sprocket nut and washer saga - Foxwood - 04-05-13

Doesn't matter really as the nut has held. Mine was visibly loose and only the locking washer was holding the sprocket on. I'd still recommend acquiring the new nut when changing the sprockets next time. Doesn't look like the nut is flush with the axle end as the new nut is, so could be that's still the old nut type. Only measuring the thickness would tell for sure. 9 mm -> old nut and 12 mm -> new nut.

No problem.
A good indicator that something might be going wrong is unordinary noise coming from the chains/sprockets that doesn't cease with lubing or tightening of the chains. At least that's how I caught onto my problem at first.  Smile  Oh and found a few pics of the 2 different nuts to visualize them.


Edit: Left one is old and right one is new.

Why bother paying? If it's not been done Yamaha are still changing them for free!
