Until now I'd never noticed the small differences in generator pulley


What is the diameter of the pulley fitted to a Mk II tri-carb - part number
AEC 910 ?

The one presently fitted to mine is 100mm.  It does not have a part number
on it.


I have a 100/6 pulley with part number AEC 291 sitting on my shelf.  

It shows the part number on the casting and has a diameter of 110 mm.  (see
photo attached.)


As a matter of interest - could the 100/6 pulley be used on a later model
without adverse effect - bearing in mind the generator speed would be only
marginally reduced.
