Front Sprocket Nut & Lockwasher Part Nos - Dave48 - 10-02-16

Recently ordered the 12mm nut & tab washer upgrade  kit from my local dealer.
The combined kit carries the Yamaha part no 90891-10124 & retails @ £2-44.
However the kit contained the 2 individually wrapped items and the respective part nos are:
12mm Nut  part no. 90179-18006
Tab washer    "  "    90215-21290
I only mention this because the modification kit & the 12mm nut are not on the normal microfiche pages but if you quote the part nos above they can be located & obtained.

Have you measured the nut?
I've just changed my c&s, went to local yam dealer for the new nut which as far as we could work out has been superceded again but by a 10mm nut!

Why would they go 10mm from 12mm, that's just daft?


Re: Front Sprocket Nut & Lockwasher Part Nos - Punkstig - 10-02-16

I know, that's why I'm asking if he's measured it- I'd assume the 12mm is still available but I didn't have the correct part number at the time and the 10mm (measured myself) is the one on the computer system)

I have a spare nut and washer kit (90891-10124) one at home, I will measure it this evening and let you know.

That code is for the 12mm one, i've seen it enough times on here.

Yes -can confirm part no 90179-18006 is the 12mm size-just measured to check!

Just discovered that I have both:

The Kit 90891-10124 with the 12mm Nut and washer in it and the Kit 90891-10124 with two separate packages in it.

The part numbers packaged in two separate packages within the package are:
90215-21290 Washer
90179-18006 12mm nut

See pics, both are 12mm and the only difference in the two is that the individually packaged nut in the package is shiny  :eek
