 -
for System 2, RH, disconnect FIN 10GA.

 (b)
 Put blanking caps on the disconnected electrical connectors.

 (c)
 Remove and discard the lockwire from the capscrews (1).

 (d)
 Identify the positions of the bracket (3) and the proximity sensor (4) before you remove them.

 (e)
 Remove the capscrews (1) and the washers (2). Remove the bracket

 (3) together with the proximity-sensor (4).

 (f)
