A2 pump, with the needle bearings on the cap and flat roller bearing on the shaft inner side. I don't see any seals on it?
What am I missing here.

Nobody has ever had the cold start handle shaft leak on an A2 pump before?

I did!
I don't remember a gasket, but maybe there was. IIRC there was an O ring on it somewhere.

I was expecting an o-ring too, but there wasn't one, and it was an OG assembly. I could post pics, I sure don't want to put it back together and have it leak.

Now with pics.
On the older style that I have re-sealed, and just checked one to make sure I'm not nuts, there IS a recess in the middle of the shaft and an o-ring to seal it. As you can see there is no such on this one. How the hell do they keep that shaft from leaking when it rides on a needle bearing? Surely not that plastic bearing cage? Help?

for sure there was an o'ring inside the cold start housing on top of the needle bearing and then the steel washer on top of that and then the lever.
maybe it got lost when you took it apart?

Thank you very, very much. I was extremely careful though, no 0-ring to be found. On the outside of the housing there is a thick washer or perhaps spacer is a better word, right before the lever on the splined end, but no o-ring.

I just did one identical - it had an o-ring in the outer portion of the cover/housing you have pictured.
It went ... lever off splined shaft ... the thick washer out ... then there was the o-ring.
And of course one where the cover meets the main case.
That joker had to have leaked some w/o that o-ring.
Mine was leaking there and it HAD the o-ring ! lol
Just in case its not real visible on yours anymore -
the splined shaft has an alignment groove on the end.
It mates to one of the two alignment marks on the lever.
Sort of like the alignment on the throttle shaft / throttle arm lever.
I've got pictures if you need any of the alignment.
No big deal but i didn't take the lever pieces apart like you have - left them bolted together.
Was going to have mine all buttoned back up tonight -
then i snapped the front lower mounting bolt. pop
Was my final round of adjustment too.
What a BIT CH

Cool, I've STILL not put the damn thing back together, got into a volvo project lately and the pump is a toy, so. I'll check it out and might bug you if I can't make sense of it. Heck I can't remember where this pump even came from right this second, I'm frazzled.
