7) Use a Phillips screw driver and remove the 4 screws which connect the diaphragm to
the motor plate. You might have to use a flat head screw driver to separate the two
halves of the diaphragm.
8) Use an adjustable wrench to remove the nut on the diaphragm. This will separate the
magnet.
9) Tap or push the center screw in order to separate the diaphragm from the magnet.
You might need to use a flat head screw driver to separate the diaphragm from the
motor plate.
*At this point you will have a better look at the magnet. The magnet rarely needs to be
replaced. If there is a lot of fine metal dust in the motor area then the magnet may
need to be replaced. Inspect the top and bottom part of the magnet. If it looks very
worn or melted proceed to the optional section on “How to Replace the Magnet”.
10) Inspect one new diaphragm. There are two halved 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.
