Set a mounting plate on a replacement
motor.
Remove a motor mounting plate from the
motor demounted from the radar antenna.
The mounting plate is secured to the motor
with stainless steel hexagon head bolts
(M8
30, SW + W assembled) at four
positions.
Attach the removed parts to the
replacement motor.
Fasten the hexagon head bolts with proper
torque (140 kgf
cm) to ensure that none of
the bolts is left without being tightened or
tightened too loosely.
Install the motor in the radar antenna.
Press the motor against the mounting face
of the motor-mounting arm projecting out
from the cabinet, and secure it in place after
making adjustment to minimize backlash.
Fasten the hexagon head bolts with proper
torque (140 kgf
cm) to ensure that none of
the bolts is left without being tightened or
tightened too loosely.
After installing the motor, apply grease to
the gear wheel.
