Hi,

Does anyone know the dimensions of a 247 crank stud that connects the barrel (part number 3360.031).

Think its an M8 about 60mm long.

thanks

Hi Glen, part # 3360.031 and part # 5160.031 are the same I believe, and are the barrel to head studs. On my 349 (5160.031) they are M8 (1.25 pitch) x 60mm, they have about 20/21mm thread either end with about 18mm non threaded shank.  Pretty sure this will be correct because  21 = Cota 247,  33= Capra,  51= 348/349, so just a common part used between models over the years that didn't change dimensions. Hope this makes some sense.

Thanks so much, make perfect sense.
