[Replacement procedure]
1) Open the upper cover (see Section 8.4.2.3) to remove
the transmitter-receiver unit.
2) Remove the hexagonal bolts (four M6 bolts) and
remove the motor. Grease the gear wheel of the
replacement motor and place it in the casing. Do not
forget to tighten the hexagonal bolts to an
appropriate torque (72 kgf-cm) so they are free of
looseness.
3) After having replaced the motor, reassemble the unit by following the disassembly
procedure in the reverse order.
Do not forget to tighten the bolts and screws, and do not forget to reconnect the cables.
Clamp the cables so they do not interfere with the rotation of the motor's rotors.
[Operation check]
After you have completed the replacement work, follow the procedure below to
check the operation.
1) Turn on the radar and emit radar waves once the countdown is finished, and check that
the radar image is correctly displayed. Check that the motor does not make any
abnormal sound when it starts to rotate, while it is rotating, or when it stops.
Remove the
four bolts.
