I'm sure I read somewhere that the oil pump can be assembled the wrong way around, is this correct?
If so what would happen? - I suspect a fair bit of smoking like it has wet sumped as the scavange pump would then have less volume than the feed pump.
I haven't inspected mine yet but I ask because I seem to be getting excessive smoking after replacing the quill seal.
Yes I have oil feed to the rockers and everywhere else, and yes the new seal is intact, in one piece and a firm fit in the crank.
The old quill seal was a loose fit in the crank end and had fairly large cracks through it which could (I presume) leach oil back through it.
All this is theory of course.
Any thoughts on the pump assembly though, and what do I need to see to confirm it is assembled correctly?
Merry Christmas, Geoff.
