Main
Seal
a.
Remove
and discard the old main seal o-ring
around the control top panel. Inspect the
sealing
surfaces
on the housing and control top panel,
replacing faulty items and cleaning
off
any
foreign material.
b Inspect the
speaker bracket assembly
to
ensure
that the two
tabs
protruding from the top of the
speaker bracket are properly seated between
the frame and the control top panel. An
improperly located
speaker bracket
will distort
the housing
in
the
seal area, causing leakage.
Cc.
Remove
the antenna before installing a new
main
seal
o-ring. Install the main
seal
o-ring by
first
placing
it
in
the groove on the antenna side
of the radio, then by slowly stretching the o-ring
around and over the frequency switch and
on/off/volume control, and finally by dropping
it
into the
groove
on the push-to-talk switch side
of
the radio.
d
Inspect again for proper seating of the main seal
all around the control top panel, and
for foreign
material. Observe carefully
to
ensure
that the
main
seal o-ring
is
not
pinched between the
radio housing and the control top panel during
insertion of the radio
chassis
into
the housing
assembly. Pinched main
seal o-rings are one
of
the most common
causes
of
vacuum test
failures.
9.
Battery Contact Seal
a.
b.
Remove
the
B+ contact
and
screw,
and the
screw
which
does
not retain
a
contact.
With the
chassis
removed
from
the radio, gently
pull
the universal connector flex from the bottom
of the radio housing. Both contact bushings
should have
red
o-rings.
If
an o-ring is missing,
place a replacement
o-ring on
the bushing and
Slide
it
all
the
way
up to the
base
of the flex.
Cc.
When
both
o-rings are
in
place, check
for
damage
to the bushing and the housing's holes.
If
there is
any damage, replace
the housing.
d Carefully replace
the
flex,
then
seat
the
bushings
in
the holes.
