TM 55-2350-224-14d. Put the transmission in neutral. For theM113A3 and M730A2, put the transmission in thesteer lock (SL) position.e. On some semitrailers the carriers will have 1to 2 inches of overhang on both sides. Position thecarrier so that the overhang is equal on both sides.f. Install chain and load binders. Specific sizesand types of chain and cable assemblies are speci-fied in table 2-3 and figures 2-1 and 2-2. Figures2-3, 2-4, and 2-5 and table 2-4 provide detailedinstructions for restraining the carriers againstforces encountered at normal speeds and operatingconditions. The transporter can use other chain andcable assemblies of adequate strength and size.The M1068 carrier only requires twoshackle assemblies. The rear tiedown pro-visions do not need shackles.Table 2–3. Bill of Materials for Transport by SemitrailerItemQuantityDescriptionShackle assembly4Shackle, NSN 4030-00-279-4475.
