Thread size/type - Primary slotted inspection plug

Post by SteveS » Sat Feb 09, 2019 4:47 pm

I have a very good primary cover but a previous owner has stripped the thread completely from one of the inspection holes that take the screw in slotted plugs (57-2166 / 70-9800). Does anyone have any idea of the thread as I was going to get the primary cover welded and then re-cut the thread.

Any help appreciated

Anita is soon to run a batch of chain case caps off, so it was fresh it my mind.
