l Note the orientation of the gate and the gate guide so that they can be refitted
in the same orientation. This is important because if the gate guide is refitted
in the wrong orientation the pump will not work properly and the gate guide
can be damaged. Use two hands to remove the rotor, the gate and the gate
guide together.
