I have a 1928 Norton 16H with a “Best & Lloyd” Mk II No.5061 oil pump.
Unfortunately, while checking/adjusting the oil flow rate, the screw threads on the outflow sheared off!
These casting were never really very well made and mine is no better than the norm.
Does anyone out there have a spare one that they would be willing to part with or know of another solution?
Many thanks
Ian

 You could helicoil it or go up a size, is it 1/4 bsp fitting? is there enough wall thickness to go up a size? if so you cold go that way and screw in a reducer to bring it back to original size if theres room.
Couple o' options there Dave..

Dunno about those solutions....looks like the whole threaded boss has become detached to me. :-\

Sure thing, the complete thread has gone :(
Will try a repair while I source a replacement part.
I think I have found someone who remanufactures the complete pump, but would prefer to use a "recycled" one.
So I'll keep looking
Thanks
