the oil pump has a path to the inner shaft of the small gear ...and the inner part of the large gear
this lets oil at high pressure side lubricate the shafts in the oil pump housing ...obviously at a loss rate depending clearances
further output of this pressure is presented at the outer bearing surface of the output shaft front roller ....so it flows through the bearing , captured in the sump - crank union
dont forget that there is a small o ring in the small gear inner , as a retainer and seal to prevent oil traversing the inner core of the output shaft , directing the oil to- through the roller bearing , after which falls to the sump
hope that helps ?
