Drum Loader Assembly MHU-133/E32K The drum loader assembly (fig. 7-14) is used to load the transporter with unlinked ammunition. The drum loader assembly places the unlinked rounds into the conveyor elements, which carry the rounds to the load unit assembly. The load unit assembly removes the rounds from the elements and places them into the retainer partitions in the entrance drum cover. You can time the load unit assembly by inserting a pin through the cover, through a hole in one of the gears, and into a hole in the housing. The drum loader consists of a load tray (onto which the rounds are placed), a belt of elements, two chutes (which control the rounds and elements when they are between the tray and the load unit), and a load unit assembly. The load unit assembly contains two gear-driven sprocket assemblies that transfer the rounds from the belt of elements to the drum cover partitions and a gearbox that drives the drum loader assembly. The gearbox can be driven by a 1/2-inch drive hand crank, making it easier to transport the rounds. A resettable counter indicates the number of rounds that have been loaded into the transporter. Drum Unload Assembly MHU-132/E32K The  drum  unload  assembly  (fig.  7-15)  removes rounds  and/or  spent  cases  from  the  transporter  and separates   them   from   each   other.   The   drum   unload assembly contains a gear-driven sprocket that removes the  rounds/spent  cases  from  the  drum  exit  cover  and places them on a tray. The tray has a hole that lets spent cases  drop  through  while  the  rounds  must  travel  the length   of   the   tray.   You   can   time   the   drum   unload assembly by inserting a pin through the cover, through a hole in one of the gears, and into a hole in the housing. Conveyor System MHU-130/E32K The conveyor system (fig. 7-16) transports rounds from    the    transporter    to    the    aircraft    system.    It simultaneously   transports   spent   cases   and   cleared rounds from the aircraft system to the transporter. The conveyor   system   is   mounted   on   the   top   of   the transporter.  It  consists  of  a  chute  support  assembly, three  ammunition  chutes,  two  element  chutes,  an  exit unit assembly, an interface unit assembly, an entrance unit assembly, and a drum drive assembly that is driven by a flexible drive shaft. CHUTE  SUPPORT  ASSEMBLY.—The   chute support assembly is a rigid structure that supports other units. It also provides stowage for other units when they aren't in use. A portion of the chute that is required for the   control   of   spent   cases   and   elements   is   a   rigid wire-form chute. This chute is part of the chute support assembly. Casters are provided on one end of the chute support assembly to aid in moving the assembly when it is not mounted on a transporter. CHUTES.—The  ammunition  and  element  chutes control the elements and rounds or spent cases when the system is operating. The chutes are flexible enough to permit interconnection of the various units. 7-12 Figure 7-14.—Drum loader.
