ROADWHEEL ARM ASSEMBLY 10-4. GENERAL The M109A6 howitzer can have two roadwheel positions disabled on each side of the vehicle and still be combat capable. The two positions, however, cannot be adjacent to one another. The first and last roadwheel positions, will accept intermediate position component. Exchange parts from intermediate positions, if required, to keep the first and last positions operative. Roadwheel arms can be obtained from other positions to provide support and separate the two adjacent positions. This will give the vehicle additional balance when operating on rough terrain. Disabled roadwheel arms should be secured or removed to prevent interference with the track. 10-2
