The front sprocket nut and washer saga - derildo - 03-07-12
Hello
I have just recently bought a 2000 Fazer 600 with only 3.5k miles, it had its last service at an official yamaha dealer in 2001 at 2800 miles.
So I think it is safe to assume that the sprocket nut /shaft check has never done. So I was going to order the mod. kit with part number: 90891-10124.
A J Suttons website does'nt recognise that part number but gives
[color=rgb(51, 51, 51)]152174630000 nut and WASHER, LOCK(3LD) as 2 separate items.
I assume these will be the modded items?
regards

I'd be inclined to get the correct nut with right part number from Fowlers of Bristol.
They'll ask you for your chassis number before they deal with you so have it on hand, but you will get the original part.
It's the 12mm thick nut that you want.
Re: The front sprocket nut and washer saga - NotAnotherHill - 03-07-12
You need to check. When I went into the dealers at Huddersfield and mentioned the modded nut, they said that the modded nut would automatically replace the original one. It doesn't. The one that they ordered from Yamaha was the 9mm nut and it has a different part number to the 12mm nut. The nut and lock washer come separately.
Re: The front sprocket nut and washer saga - darrsi - 03-07-12
It's Fowler's who the dealers ring for their parts, so cut the middle man out!
You have the correct part number anyway, but obviously mention you want the upgraded 12mm nut to make certain.

I have very recently (two weeks ago) changed sprocket and chain, at the same time I ordered the modified nut / washer quoting the part number gained from this site - This was ordered thru my local bike spares dealer (CMS in Exeter) and they supplied under the modified part number 90891-10124 (genuine number on the bag) so it is DEFINITELY available and a current part. - CMS do mail order so give them a call and I am sure they will sort you out, as I recall they had them in stock, think it cost me @£9.
Hope this helps

Re: The front sprocket nut and washer saga - YorkieFazer - 23-08-12
I have had my '51 plate Fazer now since Oct. 2011 which had done 5.5k miles now 9.5k and recently noticed the posts re. the sprocket nut issue.
I contacted my local Yamaha dealer, CMC Clay Cross, Chesterfield and mentioned the inspection notice. They knew immediately about the problem and checked if my bike had been done, it hadn't, they ordered the parts and fitted them free of charge.
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.
Re: The front sprocket nut and washer saga - DryRob - 24-08-12
My local Yam dealer didn't have a clue what I was talking about, apparently the part number hasn't been superceded on Yamaha's parts system so they can't/won't offer any advice.
I ended up buying mine through CMS in Exeter and fitted it myself when I changed the sprockets and chain. I had the guy at CMS measuring the bolts over the phone to check I was ordering the right parts and got it in the post next day, great service.
Official part number (nut and lock washer set): 90891-10124
Re: The front sprocket nut and washer saga - caretaker - 24-08-12
got mine from fowlers yesterday.
washer: 9021521290
nut: 9017918020
both fitted along with DID chain and sprox. different bike already!!
Re: The front sprocket nut and washer saga - darrsi - 24-08-12
@Caretaker, I've only ever known the new part number as 90891-10124, are you sure you haven't bought the original 9mm nut, rather than the new 12mm one? :rolleyes
Re: The front sprocket nut and washer saga - darrsi - 24-08-12
@Caretaker, i just found this on the old FOC-U forum, i was correct in saying you have the old 9mm nut on your bike, and not the 12mm modded one.
Fowlers should be well aware of this by now, and it should really flag up on their computer about this issue!
It's only a few quid for the modded nut, but it's worth changing for peace of mind in my humble opinion.......:
".....ok got to the bottom of this, spoke to the dealer earlier in the week and spoke to another parts man who confirmed his mate looked up the kit (90891-10124) but ordered the 2 separate parts. They came in 2 bags, the washer being 90215-21290 and the nut 90179-18020 and of course this was wrong.
They then placed an order to yamaha just for the kit number 90891-10124 which turned up today in one bag with the correct modded nut.
The conclusion of this in case any one else has the problem, make sure the dealer orders the kit....."
Re: The front sprocket nut and washer saga - Major Rant - 24-08-12
Its worth noting that this nut replacement ONLY needs doing if the OD of the output shaft is less than a certain size (17mm from memory).
You CAN measure this with the nut and sprocket in place: you need a steel ruler and a close-up view and an understanding of the word "parallax".
Mine is a 2000 bike, 10K miles, it has never had its nut replaced, the output shaft is definitely greater than 17mm... (by at least 0.2mm) so I'm leaving it alone.
Probably corroded on by now anyway :eek .
Re: The front sprocket nut and washer saga - darrsi - 25-08-12
@Major Rant, it took my mechanic something like 45 minutes to eventually get the nut off of my bike, and it looks like you have the same year as me.
Mind you, 10,000 miles in 12 years, do you not ride it? :lol
Re: The front sprocket nut and washer saga - rjd1 - 25-08-12
went into yam dealer asked about replacment upgraded part
couldnt be more helpful in kirkcaldy cheer`s Mark
ordered new nut and washer there and then
they even offered to fit it and torque to correct setting but was allready on my ramp stripped
i fitted and torqued myself then ran it out for them to have a check

I ride it on fine summer evenings to country pubs ... I gave up riding in the cold and wet 20 years ago :o .
Anything below 5C is 'car time'... and modern computer generated weather forecasts mean that "getting wet" is punishment for not
doing your climate simulation properly before you go out.
Use NOAA (kindly funded by the American taxpayer and me!) ... http://ready.arl.noaa.gov/READYcmet.php
You need never get wet again!
Re: The front sprocket nut and washer saga - darrsi - 27-08-12
I've been riding daily for 25 years now, never even considered driving a car, and strangely enough i'm the worlds worst car passenger!
I'm in permanent bike mode, and can't believe how car drivers don't see what i see!
I get straight in the back of a car, seat belt on, and look at the floor! :lol
Re: The front sprocket nut and washer saga - dave8204 - 28-01-13
Apologies for reviving a" thread from the dead" but this issue is still arising.
Mechanic mate of mine had an 03 Fazer 600 in last week for a new chain and sprockets,took the front sprocket cover off and there was no retaining or washer to be found! He knows the problem so the bike was checked before the modded part was ordered but obviously there are still bikes "out there" in a potentially dangerous condition.
Re: The front sprocket nut and washer saga - unfazed - 28-01-13
The problem is due to the tolerances on the output shaft. If the width of the shaft threads are less than 17.45mm diameter then the problem will not go away regardless of what nut you use. This is from experience and if you check out the thread http://foc-u.co.uk/index.php/topic,4546.msg45712.html#msg45712 you will see what I did to try and resolve the problem, eventually with Yamaha footing half the cost of the parts required to fix the problem on a bike with over 70000miles
The fix I decided to try is in the downloads section if your interested http://foc-u.co.uk/index.php?action=downloads;sa=view;down=43
Re: The front sprocket nut and washer saga - darrsi - 28-01-13
I would seriously suggest to anyone who hasn't got the modded nut to get it swapped as soon as is convenient.
Prevention is always better than cure, especially when safety is the issue!
