3. Secure fault indicator DS2 (46) with nut
(57) and lockwasher (58). Tighten nut
sufficiently to hold but not enough to
reduce adhesive thickness to less than
0,010 inch.
4. Cure adhesive for 72 hours minimum.
5. Prepare and solder tagged wires and dio-
des CR9 (47, figure 4-20, sheet 4) and
CR10 (48) to fault indicator DS2 (46,
figure 4-20, sheet 3)
(m) Relay K2 removal.
1. Remove two screws (55, figure 4-20, sheet
3) and washers (56) securing relay K2 (54)
to chassis (8). Pull relay K2 far enough
out of chassis to gain access to wires.
2. Tag and unsolder wires connected to re-
lay K2 (54); remove relay K2.
(n) Relay K2 replacement.
L Prepare and solder tagged wires to relay
K3.
2. Secure relay K2 (54) to chassis (8) with
two screws (55) and washers (56).
(o) Elasped time indicator Ml removal.
L Tag and unsolder wires connected to
elapsed time indicator M 1 (62, figure
4-20, sheet 3).
2. Remove two screws (60) and washers (61)
securing elapsed time indicator M 1 (62)
and gasket (63) to chassis (8); remove
elapsed time indicator and gasket.
(p) Elapsed time indicator Ml replacement.
1.
2.
3.
Inspect gasket (63) for damage and re-
place if required.
Secure elapsed time indicator Ml (62)
and gasket (63) to chassis (8) with two
screws (60) and washers (61).
Prepare and solder tag ed wires to
elapsed time indicator Ml (62).
(q) Diode CR2 removal.
1.
2.
Remove nut (41, figure 4-20, sheet 3) and
washer (42) securing terminal lug (43) to
diode CR2 (40).
Using socket wrench, remove diode CR2
(40) from heat sink,
(r) Diode CR2 replacement.

Isopropyl alcohol is flammable and gives
off harmful vapors. Use only in well-ven-
tilated area away from open flames and
sparks. Avoid prolonged or repeated inha-
lation of vapors.
1. Clean diode CR2 (40) and heat sink
mounting surfaces using isopropyl alco-
hol. Use lint-free cloth to apply alcohol
and to wipe parts.
2. Apply sealing compound (MIL-S-22473,
Grade C) to diode CR2 (40) threads.
3. Install diode CR2 (40) in heat sink and
tighten with socket wrench.
4. Secure terminal lug (43) to diode with nut
(41) and washer (42) .
(s) Rectifier CR3 removal.
1. Remove nut (69, figure 4-20, sheet 3),
washer (68), and screw (64) securing two
terminal lugs (65 and 66) to rectifier CR3
(67); remove terminal lug.
2. Tag and unsolder wires connected to rec-
tifier CR3 (67).
3. Usin socket wrench, remove rectifier
CR3 (67) from heat sink.
(t) Rectifier CR3 replacement.

lation of vapors.
1. Clean rectifier CR3 (67) and heat sink
mounting surfaces using isopropyl alco-
hol. Using lint-free cloth to apply alcohol
and to wipe parts.
2. Apply sealing compound (MIL-S-22473,
Grade C) to rectifier CR3 (67) threads.
3. Install rectifier CR3 (67) in heat sink and
tighten with socket wrench.
4. Prepare and solder tagged wires to recti-
fier CR3 (67).
