The orifice connector assembly is used to simulate the resistance of a protective mask when filtered air is being supplied to
fewer than the allotted crew members. The filtered air hoses remain connected to the orifice connector assembly when the gas
particulate unit is not in use. The system provides each crew station with clean, filtered, and when needed, heated air free of
toxic agents. See NBC System illustration under Location and Description of Major Components.
ARMY OIL ANALYSIS PROGRAM (AOAP)
The Army Oil Analysis Program (AOAP) provides a way of sampling and testing the oil used in your carrier. It checks for
excessive amounts of dirt, water, fuel, and wear metal. By detecting problem signs early, maintenance can be performed at a
lower level and equipment reliability is improved. Two sampling valves are installed in your carrier. The engine AOAP
sampling valve is located on the right side of the transmission. See Army Oil Analysis Program (AOAP) Sampling Valves
illustration under Location and Description of Major Components.
