Hi,
I'm doing maintenance on my BSA Golden Flash Plunger from 1954,
When removing the dynamo sprocket (the large one) I found that the nut was in quite bad condition.
I bought a new one and asked for spare part number 2-449 then I got a 3/8 26 TPI nut.
But it was wrong, when checking the cutting I found out that I need a nut 3/8 28 TPI.
That was a little odd and my supplier in Sweden have never heard of that size.
Now I wounder if anyone know where I can get a 3/8 28 TPI nut.
Second question is if anyone of you Ladies and Gentlemen knows anything about this odd size nut on a BSA?
Best regards
Stikkan
