[Ducati] Re: Ducati flywheel nut loosening

[Douglas Hunt]

snip--Flywheel rotor etc coming loose has been a recurring problem with
Ducatis for some time. Typically this happens when flywheel is changed out
for an aftermarket flywheel and the retaining nut is not properly torqued. I
do believe over the course of the past 10 years flywheel nut torque may even
have been addressed as a factory bulletin, meaning it was not a recall but
an advisory to shops to at least for it as a potential problem. Some of us
have been fortunate to simply discover a loose nut. This was the case with
me at least once. In another case nut was loose enough that it wallowed out
keyway on rotor and I had to replace rotor. So it does happen, usually it
will make noise or present other problems before it goes so far as to damage
stator and pickups.--endsnip

i just completed  the replacement of my starter sprag spring(1992
907ie),which required the removal of the rotor and flywheel and i used
permanent red loctite and 140 footlbs on  my torque wrench(too bad i didnt
have enough xtra cash to put on one of those lightweight flywheels while i
was in there)but that job wasnt near as bad as i thought it might be so
maybe this winter a lightweight flywheel project might just materialize.
