Does anyone know if the oilpump of the Ariel W/NG is interchangeable with an oilpump of a pre-unit Triumph?

It is...The holes in the pump/crankcase don't quite line up so the ones in the cases have to be chamfered by hand slightly (in one direction not all round the hole) to remedy that...

A friend of mine did the mod to two of his Ariel singles to increase oil volumes...Ian
