You’re on the wrong forum. This is for modern 961 Nortons. You need the classic Norton section.Andover norton does not show a gasket 1968-01970

Really! ? How does the pump seal?
Never thought of it that wayNo need to seal ..... The pressure side of the pump is directed to the conical seal. The suction side of the pump, the base, draws from the sump.... If there is a leak at the base, some oil from the timing chest is brought in and mixed with sump oil .... no big deal.

So really none of them need a gasket
I think I'd still fit one
