Clutch bearing collapse

[wjb]

I will soon be removing my clutch for a detent spring replacement. What is the factory torque setting for the clutch cover spring bolts?

@bebsy
After talking to @warp9.9 and @R-III-R Turbo - I went for the longer bolt solution they recommended too.
I'm not at home so cannot remember the spec's - But whilst inside - imo it makes simple sense to do it.
It's only 5 bolts and washers for added peace of mind.

It was warp9.9's idea originally I think he might have broken his clutch hub towers with too many horses

This is the spec I used. And bolt them down criss cross a little at a time to final torque of 10nm and be accurate with that.

That's brilliant mate

I'm just making a list now thanks for mentioning the sump pan does that bolt clean off? Luckily I have all 10 bearings the cage holds 10 that was a major relief as for the the wavy washer well hopefully it's bathing in the sump, it's a pisser really I just done the oil change would filtering it through and replacing it be OKi remember pulling the starter out on a freshly paved back yard and the whole 5ltrs ooozed through my fingers I was like a slippery eel didn't expect that lol

Yes the 2 sump drain strainers are held down by 3 bolts each, you can clean and reuse them with medium strength thread locker.

Oh yes the sump gasket you might buy that from triumph too.

Glad I can give something back to the community lol... 10nm

Will do - as long as it's not Corona!.

For the bolt/washer thing - I bought 5mm ID washers and reamed them open to a close 6mm hole. M6 standard holes allow (for my taste) a bit too much wiggle.

And they are standard thread M6 ISO-C bolts - Which is a 1mm pitch.

Don't be fooled into using stainless bolts they are not typically high tensile unless forged and marked Gr8.8 or higher Gr 316 are far better than Gr304 - better to use high tensile carbon steel bolts if you are going to replace them and they will need to be M6 x 1mm ISO std. Gr: 8.8 or better

Well I left myself wide open to that! Lol the offer still stands as long as I'm around that is,and as long as I get my bike fixed in time I will depart this planet a happy man

I'm going to be cringing everytime I let that clutch go using anything less... Ignorance is bliss till it blows up in your

So as not to be wasteful I ground the bolt heads of then drilled the washers to a close tolerance fit and used them on the new bolts.
