When installing the pump element with pressure limiting valve, pull out the delivery piston partly. Then insert the
pump element with pressure limiting valve from a sloping upward position into the housing until the piston head
touches the thrust ring (fig. 76). Put the element in horizontal position (fig. 68). The piston head must be in the
groove of the guide ring (fig. 74). Tighten the pump element with the according torque (fig. 73).
