7. Holding antenna drive in one
hand and the mast in other hand,
pull with a rocking motion, until
the insulator bushing and mast
are free from the tabular fitting
of antenna d r i v e (see Figure
11-13).
8. Apply 12 volts D.C. to the
green wire of the antenna drive
until the entire length of nylon
reed has been expelled, and re-
move mast. Pull on the mast to
keep the nylon taut.
NOTE: If the antenna drive is in-
operative, it will be necessary to
manually remove the nylon reed.
Place the assembly in a vise so
that the normal plane of the nylon
reed is parallel with the floor.
Using both hands, pull on the 0.30
inch diameter section of the mast
until the reed is c o m p l e t e l y
removed.
9. Using a wire hook or long nose
pliers remove bottom insulator
and water seal washer from tubu-
lar fitting of antenna drive.
NOTE: IF THE ANTENNA IS IN
WARRANTY DO NOT DISASSEM-
BLE BEYOND THIS POINT AS
IT WILL VOID THE WARRANTY
AGREEMENT.
DISASSEMBLY OF
ANTENNA DRIVE
(UNIT NOT IN WARRANTY)
If the antenna drive is no longer
covered by the manufacturer's
warranty and it is necessary to
repair the antenna drive, proceed
as follows:
10. Remove drive cover.
11. Hold the 7/16" hex nut on the
output gear assembly shaft, re-
move the 3/8" hex nut (see Fig-
ure 11-14).
12. Remove the 7/16" hex nut and
washer.
13. Lift antenna pressure adjuster
s p r i n g off shaft (see Figure
11-11).
NOTE: When removing any of the
following parts, observe their lo-
cations and positions to facilitate
reassembly.
14. Remove drive pin retainer.
15. Remove the drive pressure
beam.
16. Slide the drive pin from hole
in the shaft and take off drive
beam.
NOTE: Do not lose the 2 steel
balls in the holes at the ends of
the drive beam.
17. Remove the 2 steel balls.
18. Remove the drive disc from
the shaft.
NOTE: Exercise care not to bend
the drive disc or burr the edges
of the channel. If it is necessary
to remove drive body from motor
of motor drive unit to take out a
broken nylon reed from storage
cup, care must be used to pre-
vent pinion gears (see Figure
11-15) from falling loose. If for
any reason the gears fall out or
have been removed, it will be
necessary to realign them. This
is done by positioning the right
and left pinion gears so that the
mark on each one points at the
center of the pinion shaft of the
drive gear which receives the
motor pinion.
REASSEMBLY OF
ANTENNA DRIVE
Reassemble antenna drive com-
ponents reverse of disassembly
procedures. The following notes
apply to assembly steps on which
special emphasis is placed.
19. Reassemble the spring on the
output gear assembly shaft with
the largest diameter toward the
drive pin retainer.
20. Screw on the 7/16" hex nut 1
full turn after it touches the
spring.
NOTE: Do not reassemble the
3/8" hex nut on the shaft or snap
the drive cover in place until an-
tenna is adjusted.
