T20 Tiger Cub Engine Rebuild

Hello to all Gentleman's out there.
I am in the process to reassemble my T20 engine and come across two springs and two 5/32" (4mm) steel balls. There where in the OIL PUMP Bag. I checked and the two springs and steel balls inside the oil pump are installed. Now I am lost. Searching thru the parts pages don't show any more two steel balls with this little springs.

Where can there be missing?
By the way, I have reassemble the right side now 4 times, each time finding that something need to be installed and I missed this. Like, Tappet for the Valves, end stop for the Kick starter,

Any Help is appreciated.
I will leave this cover open for now till I know where there coming from.


OK, i went and closed the engine with out the found steel balls and springs. I just assume that someone before me, installed them under the oil pump inside the right housing, not knowing that there have the same ball and springs inside the pump.

Thanks Udo P.
