Probably a Whitworth/BSF size, or have you tried Whitworth already?

Are you able to measure across the flats of the hexagon accurately?

According to my parts books that part was used up to '65 ?

[bgreene30]

it seems it should have been 11/16W but it was in between. I ended up chaliking the nut in the vise and turning the top of the stancion with a pipe wrench. Me da's idea and it worked brilliantly. On another note, can you reccomend anyone that makes a complete engine/head gasket set of new materials? Brit gasket in Canada only has them for B44's. Would that be the same for a B40?

Thanks Much.

Certainly an Imperial size, but never ever Whitworth or even BSF in this application (these being the thread nomenclatures rather than spanner references).

I suggest BSCY and the 11/16W (reduced hex) size as also used on older Triumph's hub nuts too.
