Disassembly/Reassembly Procedures: Disassembly Procedures for SSE 5000 Radio 7-13
1. Put the housing assembly (1) aside.
2. Remove the main seal/toggle support (63) from around the chassis assembly (13).
NOTE: Inspect the main-seal/toggle support for damage. If it is damaged, replace with a
new seal prior to reassembly.
3. With the front of the radio facing upward, remove the three chassis bolts (60) from the front
chassis (50) using a ROTO-TORQ adjustable torque screwdriver with a T-10 TORX bit (see
Table 7-2 on page 7-10 for part numbers).
4. Remove the front chassis assembly (50).
5. Disconnect the encryption board (67), if present, by separating the 40-pin connector from the
VOCON board (64).
6. Disconnect the 20-pin control flex connector and the 20-pin display flex connector from the
VOCON board (64).
7. Remove the VOCON board (64) from the back chassis (13) by lifting the board from the
bottom and pulling the board out and away from the assembly.
8. Lift out the 26-pin compression connector (62).
9. Remove the main shield (61) and transceiver board (65) from the back chassis (13) in unison
by lifting both parts from the bottom of the radio until they clear the center boss of the back
chassis. Once clear of the center boss, they can be pulled out and away from the assembly.
NOTE: Inspect the back chassis (13) to make sure that the thermal pad (26) is attached to
the chassis. If the pad is attached to the transceiver board, remove it from the board,
discard it, and attach a new thermal pad to the chassis heat sink island.
10. Separate the main shield (61) from the transceiver board (65).
NOTE: Inspect the conductive gasket of the main shield for damage. If the conductive
gasket seal is damaged, discard the main shield and replace it with a new one.
NOTE: The hex lock nuts (16), which hold the housing to the chassis assembly (13), are located in
recesses at the bottom of the back chassis. These nuts are retained by the hex lock nut
retainers (17). If the hex lock nuts need to be replaced, they can be removed with tweezers.

2. Remove the volume control and channel select spanner nuts (14) using a ROTO-TORQ
adjustable torque screwdriver with the volume/channel switch spanner nut bit (see Table 7-
2 on page 7-10 for part numbers).
3. Remove the volume control and channel select wave washers (19).
4. Remove the antenna spanner nut (15) using a ROTO-TORQ adjustable torque screwdriver
with the antenna spanner nut bit (see Table 7-2 on page 7-10 for part numbers).
5. Remove the antenna star lock washer (18) and the antenna wave washer (20).
6. Remove the external RF retainer clip (35) by sliding the clip towards the bottom of the radio,
in a direction parallel to the back face of the radio, until the clip disengages from the external
RF contact (22) and the clip is free of the back chassis (13).
7. Remove the external RF contact (22) from the control top (40) by gently pushing the contact
from the inside of the radio until it is free from the back of the radio.
