Jubilee Alternator rotor nut size

Forums

Evening all,

anyone know what size the alternator rotor nut is on the Jubilee?

I can’t find anything hear or online and tried all my thread gauges, nothing seems to fit.

Im just trying to get another nut so I can secure the timing disc!

thanks

1/2" BSF, 16TPI.

Had to tidy up the thread on my Navigator, a die of this size did the job.

I made a new, longer nut with an external thread (3/4" x 26TPI) to fit a timing disc so that there is no need to disturb the nut, plenty of room under the chain case cover to do this.

That sounds a very handy alteration you have carried out there John. 

For those of us without the expertise or equipment, perhaps you could knock up a batch for the Club Shop to offer? I'd certainly take a couple!
