Title: Dommie rear disc
Post by: Moto63 on May 19, 2017, 09:00:38 AM

Morning chaps, hopefully someone out there can help out. Does anyone know if the rear disc on a Honda dominator shud av a wavy washer under the rear disc bolts. I've bought a disc and new bolts but there is still a fair bit of "float" in the disc.
Thanks in advance... Michael

Aye Michael,

Try this link below, it may help. If the year is incorrect then you have the option to view years between 1988 and 1999.

My regards, Bill

hi michael
there are no wavey washers under the bolts on the dommie  ,you must have the wrong type of disc bolt ,maybe the shoulder on the bolts you have is too long  the ones on my bike have  approx 5mm shoulder before the thread starts ,tommy
o that measurment is taken from a 1994 rdo2 model

My main problem is that I don't know what year the back wheel is from so if anyone out there can possibly give me some tips as to how to possibly identify one year wheel from another that would be great... thanks in advance.
Cheers, Michael

Aye Michael,

Anorak job here and I don't even own one of these beasties!  ::)

Using Fowlers and CMS' websites, as previously supplied, part numbers change for the rear brake disc retaining bolts in 1991 - 1992 model years.

1988 - 1991 = 90105KS6700

1992 - 1999 = 90105KAE870

Fowlers appear to give the same dimensions for both bolts, but by searching Google by entering just the Honda part number there appear to be two differing dimensions!  ::)

1988 - 1991 = 90105KS6700 appears to have dimensions of 6 x 20 link: CMS_parts (https://www.cmsnl.com/products/bolt-disk-6x20_90105ks6700/#.WSAkDje1uJA)

1992 - 1999 = 90105KAE870 appears to have dimensions of 6 x 17 link: CMS_parts (https://www.cmsnl.com/honda-nx650-dominator-1992-n-englandkph_model3907/bolt-disk-6x17_90105kae870/#.WSAlWTe1uJA)

My deduction would be that you have the 6mm x 20mm bolts, when you should have the 6mm x 17mm bolts!  :-[  Neither appears to be difficult to obtain.

I hope this helps.

My regards, Bill
