1. Remove the closing cap (key 3) and turn the
adjusting nut (key 2) counterclockwise until all
compression is removed from the control spring
(key 1). If the only further maintenance is to change
the control spring (key 1), skip to step 10.
2. Remove the spring case cap screws (key 21) and
hex nuts (key 22) and remove the spring case
(key 23).
3. Remove the diaphragm (key 5) and attached
parts by tilting it so the pusher post (key 8) slips
off the lever assembly (key 9). To separate the
diaphragm (key 5) from the attached parts, unscrew
the diaphragm hex nut (key 37). If the only further
maintenance is to replace the diaphragm parts or
change the control spring (key 1), skip to step 8.
