The M113 Family of Vehicles (FOV) power train delivers power from the engine
through a transfer case to an automatic, three speed forward, one speed reverse
transmission. The transfer assembly has an in/out drive plate connection to disengage
the transmission. The transmission delivers power to a control differential which
produces the steering control and delivers power to the right and left final drives.
Steering is provided by application of brake shoes internal to the control
differential. A pivot steer capability is provided through two master cylinders and disk
brake calipers mounted external to the control differential.
