Figure 13 Lower Diaphragm Installation
27. Reinstall the O-ring in the groove on the outside of the diaphragm.
28. Slightly roll the diaphragm down the piston until the diaphragm (overlaps)
covers the O-ring evenly around the bottom.
29. Install the piston over the motor and reinstall the three screws that were
previously removed.
NOTE
The lip on the lower diaphragm is captured between the upper and lower
cylinders, and must be correctly installed.
30. Place the upper cylinder on the lip of the diaphragm, and carefully fit the
lip into the groove in the upper cylinder.
31. Carefully press the upper cylinder down until it is resting on the lower cyl-
inder. Note that the cylinders are keyed to fit together in only one position.
Look down through the upper cylinder and verify that the lower diaphragm
shows a uniform roll around its circumference.
