f. Wipe a thin film of Halocarbon grease on the O-ring (5) before
installing it on the stem.
g. Look through the opening in the top of the injector with a flash-
light and examine the conical hole and O-ring in diaphragm screw
immediately below. If it is smooth and clean, merely reinstall the
stem, making sure the large O-ring is under the head. If the coni-
cal hole and O-ring show film deposits, clinging particles, or a
rough surface, disassemble the injector. Unscrew the gas line union
nut (15) and discard O-ring (16).
h. Remove six bolts and lift off injector flange. Carefully remove the
diaphragm assembly. Using a fine, pointed tool, pierce the O-ring
(8) and remove it from the valve seat (7). Clean the conical hole
in the diaphragm screw. Do not scrape with a knife blade or a
tapered reamer. Scrub out with a cloth plug. Dissolve resistant
deposit with 10% muriatic (hydrochloric) acid. It is not necessary
to disassemble the diaphragm to do this.
