2. Install antenna in position from beneath car,
being certain that antenna clamp is over grounding
tab of escutcheon retaining spring.
3. Install screw holding antenna assembly and
bracket to right fender dustshield.
4. Connect lead-in cable to support tube.
5. Connect motor leads at plastic connector.
6. Tighten clamp screw retaining top of antenna
to escutcheon.
7. Lower hood.
92. Antenna Disassembly
and Assembly
a. Disassembly (Fig. 12-86)
1. Remove three s c r e w s securing retaining
clamp to support tube and remove clamp.
2. Remove two s c r e w s holding lead-in re-
ceptacle to support tube and remove receptacle.
3. Unsolder mast wire from pin and insulator
assembly, and separate assembly from mast wire.
NOTE: Do not overheat pin by slow solder-
ing because excessive heat will damage insula-
tor.
4. Remove three screws securing support tube
to deive assembly and remove support tube with
top insulator attached by pulling it loose from
drive assembly.
5. Remove outer mast section, with insulator
bushing attached, from tubular fitting on drive
assembly.
6. Inner mast section with nylon cord attached
can be detached from drive assembly by applying
12 volts to motor leads while grounding motor.
NOTE: Keep nylon cord taut to prevent kink-
ing or bending.
7. Remove bottom insulator from tubular fitting
with the aid of a small drill inserted through
each of the drain holes at bottom of tubular fitting.
8. Unscrew tip from inner telescopic section.
b. Assembly
1. Install tip on inner telescopic section.
2. Insert bottom insulator in tubular fitting with
slotted protrusion down, aligning slots of insulator
with ears in tubular fitting.
3. Insert nylon cord through bottom insulator
and into drive assembly as far as possible with-
out applying force. Then apply 12 volts to the
motor leads to retract cord into drive assembly.
Be certain to keep cord taut to prevent kinking.
4. Place outer mast section over inner section,
aligning slots of pin and insulator assembly with
ears in tubular fitting.
5. Place support tube over mast assembly,
aligning tang on tube with slot provided in tubular
fitting. Pull mast wire through pin and insulator
hole before securing support tube with three
screws.
6. Insert mast wire into pin and insulator as-
sembly, and solder.
NOTE: Be certain to use only resin type
solder. Do not overheat.
7. Position lead-in receptacle over pin and in-
sulator assembly and secure with two screws.
8. Install clamp over support tube and secure
with three screws.
93. Antenna Maintenance and
Repair Procedure
Many antenna troubles can be prevented by
cleaning and lightly oiling the antenna rod at
periodic intervals. Cleaning is easily performed
at oil change intervals, or when a car is being
washed, by wiping the rod with a soft cloth.
NOTE:
to make
plugged.
If car has been undercoated, check
sure that drain holes have not been
a. Moisture in Cylinder
Weak reception or fading is often caused by
moisture in the support tube, due to condensation
or leakage through the insulating bushings. If
trouble has been traced to moisture in the tube,
the antenna must be removed, disassembled and
thoroughly cleaned. All moisture can be removed
by blowing it out with compressed air, then push-
ing a clean, dry cloth through the support tube,
as far as possible. Before assembling antenna,
check drain holes in motor housing below body
tube mounting point to be sure they are not ob-
structed.
b. Antenna Will Not Raise or Lower
This condition can be due to a blown fuse, loose
electrical connections at the switch on the re-
ceiver unit or at the antenna motor, a bent an-
tenna mast, or a loose or improperly positioned
station selector knob. If a check of these causes
fails to correct the condition, disassemble the
antenna and replace any inoperative parts.
