Pete I just changed the oil in my WM20 gearbox and if I'd tried to put a pint in, half of it would be on the floor. It's only a shallow bath with quite a bit of metal parts in it "EUREKA!"......When it's full, it's full. Ron:relaxed:
Thanks Ron.
I was just a bit worried as the M20 and Haynes (:face_with_rolling_eyes: ) manuals both quoted a pint. I thought maybe it was not making its way to the main case, with all the whirly bits in it, and I had just filled the outer case.
