front sprocket nut + SERVICE NOTE 2005-12A

[Paulfzs]

from the old board...


is the info correct? i can phone any yam dealer and ask them to do this for me?



The Inspection Notice (not a recall) that Yamaha issued to the Dealerships essentially says the following:
Any FZS600 Fazers model (1998-2003), regardless of whether it still in warranty or has been serviced officially in the Dealer channel can be inspected at any official Dealer.Remove the existing nut and washer.Measure the drive shaft OD of the threaded part (micrometer or vernier caliper).If >= 17.5 mm -clean threads and fit a new washer & nut with threadlock.If < 17.5 mm -the drive shaft must be replaced. (This work could take between 1 day to 2 weeks depending on Dealer workload).

You can try your luck basically.


It's their own words on their own service note, so they only have themselves to blame if people try and take them up on the offer, because it is a genuine fuck up on their behalf.
But, even if you were to get a result, don't expect the work to get done in the very near future, because i'd imagine paying customers will get sorted out first, especially as these bikes are teenagers now.
And your bike has certainly had a bit of a misspent youth.

We all have a mid life crisis including bikes i feel mine works better if i go really fast! its already lasted 6x longer longer than my original engine which i rode like a girl!

My front sprocket and nut is original I think on my 98 with 27,500 miles bike, does this, in your opinions, mean I don't need to change the nut?
I've just purchased the new nut and washer and was going to replace them next month when I get a new chain and front sprocket.
Cheers.

[fazersharp]

I would never advise one way or the other, but just like you i have the oem one untouched from factory and so far all is sound 18k miles and you and paulfzs are an extra 2 people who have 98s with no issues, referring to my original post looking for 98s who have had the problem on an untouched factory nut ) to rule out misfitting by previous owners ) there were no 98s reporting the issue.
I would 100% fit the new nut when you do the chain, I have the new nut ready to do the same. 

[sinto]

Yeah, as far as i can work out from previous owners and all the receipts I got with the bike for all the work done on it, the nut has never been replaced, nor has the chain, hence the reason I'm going to do the lot, I'm just using as is, as if it's not moved by now, will it move? That's just my reasoning, I would rather wait till bike is off road fir the winter and do all my stuff then as it's easier to do and I don't lose riding time

I think you're right to change the nut as Yamaha have highlighted the old 9mm one as a potential safety issue, I'm certainly going to make sure mine has the thicker one before I start riding it.
As an aside, when you get your new chain it's recommended that you change both front and rear sprockets at the same time ( wasn't sure whether you'd just missed that out of your post)

Yes Steve, I just missed it out, the whole lot will get done :-)

I've had a look at mine tonight and have the 9mm nut, in fact it looks like it's never been touched from new.
Looks like I'll have a bit more fettling to do now too after uncovering this ...........   I love to see a well maintained machine!

Mine was 98 its now got a 2003 engine in!


the original 98 sprocket was welded on (previous owner)

Grease the bearings under the clutch adjustment nut while it's apart.

It will move. Just  use long enough steel breaker bar. I've used steel this steel pipe from B&Q:

That's certainly one way of making sure it doesn't come off!

I'm surprised you could actually see the nut, if the outer casing has anything to go by, it must of been fairly well hidden

In his defence it didnt haha, i didn't know till i took the engine out! even then i didn't notice till i glanced at it in the wheel barrow.
