TRACK AND SUSPENSION
A broken roadwheel arm will cause serious operational limitations, if damage occurs in
the first or fifth roadwheel position. If either of these positions is damaged, the
complete assembly should be changed from another position. Positions 1 and 5 are
critical and are identical to position 2, with shock absorber mount
q Degraded mobility
q 2 soldiers
q 1-2 hours
q Roadwheel arm support
q Short track
q Tie up support arm
1. Break track if
2. Remove damaged
3. Replace arm from another roadwheel position. If 1 or 5 position is damaged, use
roadwheel arm from position 2 to maintain shock absorber use.
4. Reconnect and tension track.
5. Record the BDAR action taken. When the mission is completed, as soon as
practicable, repair the vehicle using standard maintenance procedures.
8-10. SUSPENSION COMPONENT INTERCHANGEABILITY
Replacement parts may not be available through normal supply channels. Replacements
can be modified if obtained from other vehicles in the M113 Family of Vehicles. Most
parts will be usable without modification or improvised mounting.
Improved suspension, A2 series, have heavy duty shock absorbers and torsion bars
but these parts will exchange with the older parts. Left and right torsion bars cannot
be cross exchanged.
