Note. If the platform must be assembled, install the suspension bracket assemblies when
assembling the platform. See Figure 5-1 for the location of the suspension bracket assemblies.
Installing suspension links. Install a tandem link on the front of each rail according to
FM 4-20.102/MCRP 4-11.3J/NAVSEA SS400-AB-MMO-010/TO 13C7-1-5.
Installing tandem links. Install a tandem link on the front of each rail according to
FM 4-20.102/MCRP 4-11.3J/NAVSEA SS400-AB-MMO-010/TO 13C7-1-5, and as shown in
Figure 5-1.
