Propshaft adaptor bolts

Need to get some Bolts and Nuts for propshaft to sprocket adaptor flange. Will normal 8.8 high tensile bolts and nuts be OK?
Or do I need to source some 10 or 12s as per the Ford screws at the prop to diff joint?

Cheers
Colin

Hi Colin,

I used exactly the same as Dave for the prop to adapter and bought some bolts from ford for the rear diff to prop.

You're catching me up Colin! Let me know if you need a spacer between the propshaft adapter and engine as I had a few spares made when I got mine done.

Should be able to drive mine soon albeit without bodywork but will be a good feeling!

Rich.

Thanks, I`m off to the bolt shop now
Trust me, I`m not catching you up
Thanks for the spacer offer, I think i`m ok having found some washers in the parts shed
Good luck with the unbodied test drive, don`t forget your shades

Got my high tensile cap heads yesterday, very nice!
However it got me thinking as to whether they should be matched with high tensile nuts if such a thing exists?
If you can tighten the bolt tighter than you would a normal one ,what stops the thread stripping on a normal nut, or are all nuts high tensile?
I don`t normally spend so much time thinking its probably just that its the dreaded propshaaaaft of doom that needs the bolts so want it to stay bolted

colin..
it's the bolts that are high tensile...if you use the 270 threadlock they won't come apart....
test it ..get a spare nut and bolt.. use some locktite on it bolt something together with it... leave it a day then try and undo it...
dave..

use the proper lockite though...it is a brown/red bottle .. and green in colour...

Thanks...........Threadlock, yes i`ll use some of that .........
Forgive my old age and stupidity...but.....I`m still thinking!!!!!!!!!!!!!
So,
Ignoring the issues with them coming undone, lets say I was bolting 2 inanimate metal plates together
What then is the benefit of using high tensile bolts ? Is there any?

in a word ... no
high tensile is usually used for high stress applications ... ie .. suspension joints.. steering arms..and prop bolts..stuff like that.
anything that has to take sheer loads if you like..

am i right in thinking you are spacing out the prop flange to clear the final drive nut on your engine?

Correct, apparrently, the Fireblade engine output shaft varies in length, and is nearly allways 3mm longer than the thicknesss of the propshaft adaptor, certainly the one supplied by MK.
I think we ought to contact Honda about their engineering tolerances?
