4-25. Assembly. This section provides instruc-
tions to assemble assemblies and subassemblies
which have been repaired.
4-26. Assembly of Balancer/Phazor (Fig. C-2).
NOTE
Refer to Balancer schematic
diagram(fig, FO-1) and Phazor
schematic diagram (Fig. FO-2) for con-
nection of electrical leads.
a. Install R.P.M. TUNE resistor R1201
follows:
(21) as
(1) Assemble resistor to bracket (26) with
nut and lockwasher provided with resistor,
(2) Turn shaft of R1201 fully
counterclockwise.
(3) Set 10-turn dial (27) to 000 and assemble
dial to bracket (26) and R1201. Tighten dial to
R1201 shaft with two setscrews in dial.
(4) Assemble R1201, bracket (26), and 10-
turn dial to Balancer with two screws (23),
washers (24), nuts (25), and springs (22).
(5) Solder leads to R1201.
(6) Press knob on dial.
b. Install IPS meter M1201 (17) as follows:
(1) Place meter in position on panel and
secure with three screws (18), washers (19), and
nuts (20).
(2) Connect red lead to + terminal of meter
and black lead to - terminal.
c. Install rear cover (1) with four screws (2).
4-27. Assembly of Strobex (Fig. C-5).
a.
NOTE
Refer to Strobex schematic diagram
(fig. FO-3) for connection of electrical
leads.
Install handle assembly as follows:
(1) Place S1201 (52) and plate (53) in slot in
one-half of handle (49).
(2) Feed cable (46) wires through hole in
bottom of handle and feed remaining wires
through the top of the handle,
(3) Join the two handle halves with three
screws (50) and nuts (51), Ensure that switch and
plate is in groove.
(4) Feed wires through hole
case (55).
(5) Place trigger in position
in bottom of
and attach ban-
dle to case (55) with four screws (47) and washers
(48).
(6) Solder item 4, cable leads to MODE
switch S501 (11) and connector P502 (5).
b. Install reflector assembly (43) through rear
of case. Attach to case with four screws (30) and
nus (27).
CAUTION
Thermal stress will cause lens (26) to
break if nuts (27) are tightened against
case (55).
c. Install lens (26) with four nuts (27), Tighten
nuts and then turn back 1/4 turn.
d. Solder leads to diode package (24) and install
in case with three screws (25).
e. Solder leads to capacitors C1201 (23) and
C1201 (22) and instaall with two screws (21) and
clips (20).
f. Install circuit card C3984 (4) in connector (5)
with components side to inside of case.
g. Attach rear cover (18) to case (55) with six
screws (1), lockwashers (2), and flatwashers (3).
4-28. Installation of Flash Tube.
a. Remove lens if Nor-Previously Removed (4-
23 b).
b. Clean reflector (43, fig. C-5) with a clean lint-
free cloth dampened with a mild detergent and
water solution. Wipe dry with a clean lint-free
cloth.
WARNING
The flash tube is at several at-
mospheres pressure and may cause in-
jury if broken. Wear a safety shield or
safety glasses. Avoid twisting or ben-
ding the flashg tube or the quartz glass
will fracture.
CAUTION
Avoid touching glass envelope of flash
tube with fingers. Body oils from
fingerprints will cause etching of the
glass when hot, resulting in fracture of
the glass.
