Stripped Clutch Nut
Posted: Sat Mar 23, 2024 3:39 am
Ducati Guys,
I’m doing some mods to my ‘66 Mark3.
Kick starter coil spring conversion.
Power Dynamo alternator
Battery, regulator, & fuses
Dyna S ignition
Advance unit modified for increased advance
I finished most of the work, and was installing the nut on the clutch shaft. The new alternator is slightly wider so the crank gear
Has moved outward. They include a wider spacer to put behind the clutch housing so the gears still match up. This reduces the
Shaft protrusion out of the clutch hub, when the nut was screwed on and lightly tightened, the end of the shaft appeared about
Flush with the outer nut edge. I attempted to tighten it to 60 ft-lb, but it stripped at about 50 ft-lb. I am hoping the shaft is harder than the nut. The shaft threads appear ok, but I am not certain. I will see if a new nut will tighten properly.
I am not anxious to put in a new shaft.
Dave
