10) In spect one new diaphragm. There are two halves for each diaphragm. Notice that the half with the round soft
rubber looks different on each side. One side has a rectangular impression. This impression must line up with
the magnet screw. There is also an oval peg on the hard black plastic part which must align properly with the
motor plate.
12 ) Again, properly align the hard plastic with the motor plate. Be sure it is set flush with the motor plate and the
oval plug is aligned with hole in motor plate. Now, align the second outer half diaphragm with the first half
screw holes. Squeeze both halves together with your fingers really hard. The two halves will not completely
connect until you screw them together.
11) Align the new half diaphragm properly with the magnet screw and the motor plate. Push the diaphragm
completely un til it touches the magnet screw. You might need to push the so ft rubber from behind with
you r fi nger. Use the wrench to screw on the new washer and nut. B e sure the new nut is very ti ght. (You
may also use a drop o f removable” Lock-Tight” glue to secure the nut to the magnet.)
