2. Remove screw (120), washer (121), and
shoulder washer (122) securing terminal
lug (123) to chassis (8).
3. Unsolder capacitor terminal lug (123);
remove capacitor.
(z) Capacitors C1, C2, and C3 replacement.

4.
Clean old adhesive from area on chassis
(8) where capacitor is to be installed.
Prepare and solder capacitor and tagged
wires to standoff and terminal lug.
Secure terminal lug (123) to chassis (8)
with screw (120), washer (121), and shoul-
der washer (122).
Bond capacitor to wail of chassis (8) using
urethane adhesive (724-14C).
(aa) Capacitor C5 and thermostatic switch S2
removal.
1. Tag and unsolder wires connected to capaci-
tor C5 (126.2) and thermostatic switch S2
(126.1)0. Remove capacitor.
2. Remove thermostatic switch.
(ab) Capacitor C5 and thermostatic switch S2
replacement.
1. Clean old adhesive from area on chassis (8)
where thermostatic switch is to be installed.
2. Bond thermostatic switch to wall of chassis
(8) using epoxy adhesive (163-4LVFF).
3. prepare and solder capacitor and tagged
wires to thermostatic switch. Place insula-
tion sleeving (MIL-1-22129) on capacitor
leads.
4. Bond capacitor to wall of chassis (8) using
urethane adhesive (724-14C).
(ac) Connectors 3J1, 3J2, 3J3, 3J5, and J6.
1. When replacing connectors 3J1, 3J2. and
3J3, torque mounting nut 90 to 95 inch-
pounds.
2. When replacing connector 3J5, torque
mounting nut 85 to 90 inch-pounds.
3. Check electrical bonding between 3J1, 3J2,
3J3, 3J5. and J6 mounting nuts and chassis
with an ohmmeter. Resistance should be
5 milliohms maximum.
(10) Output filter circuit card assembly A9 repair.
Repair of the output circuit card assembly A9 (130,
figure 4-20, sheet 6) consists of replacing defective
components.
See figure 4-21 for a parts location dia-
gram and repair output filter circuit card assembly A9
using standard shop practices.
(11) Wire harness repair. Repair of the wire har-
ness consists of replacing broken or burned wires. Refer
to wires listed in table 4-4 and repair wiring using
standard shop practices.
4-20. Cable and Connector Repair.
a. General. Cable repair consists of connector pin
replacement, terminal lug replacement, and repair of
broken wires by substituting wires. Connectors are
repaired by pin replacement.
(1) Connector pins are replaced from the connec-
tor rear. Remove the appropriate covers and panels to
obtain access to chassis-mounted connectors. The back-
shell must be disassembled for cable connectors.
(2) After access is obtained, remove the defective
pin and cut off the wire.
Prepare the wire and crimp a
new pin on the wire. If the newly prepared wire is too
short, there are usually spare wires in cables. Insert the
new pin into the connector and reassemble the equip-
ment.
(3) Procedures for backshell disasssembly/assem-
bly, pin removal and replacement, crimping tool opera-
tion, and lug replacement are given below.
Use a strap wrench (figure 4-22) to loosen
or tighten backshell components which
do not have wrench flats. Use of pliers,
pipe wrench, etc., may damage the con-
nectors.
