Hi all,
anyone know of the technical name for the 5 speed Enfield gearbox mainshft splines?

If anyone has the technical drawings so much the better.

Cheers

'92 Enfield + Hatz 1B40: street legal, weld up stainless exhaust, check engine rpm and change final drive sprocket.

Thanks for the reply, but I needed a technical diagram of the splines, noting every angle, and mesurments of grooves and splines.
There should be a propper tech name for this spline arangment, Bsi, Din, Ansi etc.

:D

Sorry should have said, it's the splines where the clutch fits over.

Thanks for that, I'm sure that they will be very useful.

I was going to get an engineering company to make a bolt together coupling to extend the 5 speed gearbox shaft, using the tech drawing for guidance.
This would have saved me butchering a couple of Enfield clutch centres. But I have decided to just get on and make it. :)

Thats odd the post has come up twice. Bizarre. :)
