Thread size and pitch for the flywheel puller was created by Txnathan

Hi all,

Does anyone know the thread diameter and pitch for the inside of the flywheel on a 1970 DT1C? I looks like a puller is made for it so I would like to make my own for fun.

Thanks Nathan

Thanks MarkT,

I enjoy machining and fabricating parts which is one of the reasons I wanted this project but it’s hard to beat that price so I ordered one.
