Mazzo forks damper rod allen head bolt torque spec

[breganzane]

It's possible in theory for the bolt to unscrew all the way if the if the damper rod rotates rather than the bolt. Any scenario of the bolt coming unscrewed seems pretty unlikely though, for the reasons you mention.

I suppose so yeah, but the damper rod has the weight of the bike and fork spring tension between it and the slider so there's a fair disincentive for it to unscrew. In any case, it's not how Denis Neil's accident happened so I guess that answers that question.

And to top it off a proper Honda team to boot. O yer didn't something similar happen to Casey Stoner a couple of years back on a Suzuka 8hr ride.

That was the throttle jamming at WOT, he clutched it and you could hear the motor banging off the rev limiter before impact but of course in angel gear he didn't make the next corner. Being Honda we never found out the cause - software or mechanical.

Sorry, but some wrong info going about here I think. All Marzocchis I have come across have an M12 bottom bolt, it is a 'socket low head' type, so the inhex is one size smaller than a standard cap screw at 8mm. It should have a 12mm ID 'dowty' type rubber-sealed solid washer.

Yes, that is what is in use on my Marzocchi's and yes the axle would prevent the M12s from coming all the way out. Thanks for all the info.
