Sports: RE: [DucatiST] Re: Shiny New Clutch

Re: stainless steel fasteners…

I had never experienced this galling until about 8 years ago when I was building myself a motorcycle trailer and for some reason needed to remove a 3/8” stainless steel bolt & nut I had recently installed (without having using never-seize). The threads had seized completely into a solid mass, and I had to use an impact gun to break off the bolt. The threads had been just fine when assembled.

I would never have believed this possible in a short time, had I not seen it myself. Needless to say, I now take stainless steel galling seriously.

Use nickel anti-seize on the threads or you will run the risk of galling and have a permanent clutch assembly

Cool, good info - I will see if I can grab some stainless bolts instead.

Watch the black oxidized bolts, they will rust quickly. Stainless is the way to go, you can even hit them with some black paint, finger nail polish or even permanent marker( in a pinch).

I am replacing some myself after less than a year. I will try not to make that mistake again, and get the proper hardware.

Good to hear of your clutch satisfaction, Richard, and I hope neutral is still freely available!

As to spring bolts, I'd say definitely tightened by (sensitive) feel unless you get a very low register torque wrench. The springs should themselves have a locking effect, though I daresay someone's had them back out! It's a toss-up which way to go for bolt quality, as cheap soft bolts may be a bit soft but you don't want the threads to strip in the posts rather than the heads come off.

Do please send Charlie our collective thanks for his generous donation of a clutch tool! Over here, I have a homemade device which weighs a good deal more than a Charlie water-jet alloy tool, and that's available if needed, so long as postage is covered.
