3. Lift the air sensor cable and carefully using a 2 mm shaft, push the hinge
pin from the air sensor side (left side) and remove it from the pressure
sensor side. THE HINGE PIN WILL ONLY GO ONE WAY. The hinge
pin must be removed from the right side of the pump and reinserted into
the right side of the pump. Pushing the hinge pin the wrong way will
cause damage to the pump.
4. Removing the hinge pin allows for separation and removal of the door, pressing
plate, and springs.
