WEATHER RADAR RECEIVER/TRANSMITTER MOUNT
________________________________________ BLOWER ASSEMBLY - REMOVAL/INSTALLATION
______________________________________
1. General_______
A. This subject has two tasks. The first task is a removal of the blower assembly on the receiver/transmitter (R/T) mount. The second task is for the installation of the blower assembly on the R/T mount.
B. PASSENGER AIRPLANES; The blower assemblies are on the dual R/T mount on the E5 rack. You get access through the access opening in the right crawlway forward of the main electronic equipment center. You use this procedure to remove the blower assembly only, not the full R/T mount.
C. FREIGHTER AIRPLANES; The blower assembly on each mount is found below the floor compartment between station 180 and 220. You use this procedure to remove the blower assembly only, not the full R/T mount.
