Mark shipping weight and center of balancelocation on both sides of the carrier.5-7-2. Specific Carrier Preparations for Airlift:a. M106, M106A1, and M106A2. Securebase plate for the 107-mm mortar insidecarrier.b. M548 and M548A1. Secure the bowscanvas inside the carrier.c. M577, M577A1, and M577A2. Removeantenna extensions and guards to reducethetheandthethecarrier to its lowest configuration. Rear ramprequires special preparation to prevent it fromfalling during transport. See appendix E for in-structions.d. M901, M901A1, and M981. Reduce theheight of the carrier for transport on the C-130and C–141 aircraft by removing the armored sightcover from the top of the TOW launcher ortargeting head. The wide field of view (WFOV)sight must also be removed (by a qualified fire-control technician). Appendix D contains detailedprocedures for converting from the high stow tothe low stow position.e. M1068. Remove the antenna extensions andguards, auxiliary power unit, and tent light setmounts to reduce the carrier to its lowest configu-ration.5-7-3. Loading Instructionsa. Metal parts of the carrier tracks must notmake contact with the aircraft loading ramp orcargo compartment floor. Prolonged operation ofvehicles causes the rubber track pads to chip,crack, and wear, thus eliminating the rubber padprotection and allowing the steel track shoes toimpact the surface. Therefore, the use of shoring isalways required when loading and offloading thecarriers. Use 2- by 12-inch lumber to provide tworows of shoring 24 inches wide and spaced tomatch the carrier tracks. The loaded height of thecarriers may be reduced slightly by use of 3/4inchor 1/2-inch plywood shoring instead of 2- by 12-inchlumber. Lay the shoring from the ground end ofthe aircraft ramp extension into the cargo com-partment, so that when the carrier is in thetiedown position, the tracks are on the shoring.Shoring is provided by the transported unit or bythe shipping activity.b. Place the transmission in neutral and set theparking brake, after the carrier has been posi-tioned aboard the aircraft.c. Restraint factors (g loads) for minimum ac-ceptable conditions (specified for crew and passen-ger safety in the event of a controlled emergencylanding) are specified in the applicable aircraftTechnical Orders (TO 1C-5A-9, TO 1C-130A-9,and TO 1C-141A–9).d. For the M113A3 and M730A2, put the trans-mission in SL position.5 - 2
