1-16. EQUIPMENT OPERATION (continued).
SUSPENSION SYSTEM
Two final drive assemblies transfer power from the powerpack to the track through two drive sprocket and hub
assemblies. Seven pairs of roadwheels on each side of the vehicle help center the tracks on the drive sprocket and
hub assemblies. Track tension is maintained by two idler wheels, which are connected to grease actuated track
adjusters.
Each pair of roadwheels is supported by a roadwheel arm assembly. Each roadwheel arm assembly is connected
to a torsion bar, which is anchored to the hull, to help maintain contact between the roadwheels and track. Four shock
absorbers, connected to the two pairs of front and rear roadwheels, help smooth the ride of the vehicle.
