5 Disconnect and remove 3 x 4 bolts
and washers connecting the polari-
sation switch to the three
waveguides (see fig. 3.180). All bolts are 8-32 UNC bolts.
When separating painted flanges it is often that a sharp knife is used to cut through the paint at the interface so the paint does not crack or flake
when removing the flange - saves
time for the touch up once re-assem-
bled.
6 Disconnect the electrical connector
from the polarisation switch motor.
Firstly, remove the vulcanizing tape
surrounding the connector. Second-
ly, unplug the connector. See fig.
3.181.
