The differential consists of three major assemblies. These are the right angle gearbox (1), steering unit with
brake shoes (2), and two output shafts (3).
Power flow is from the transmission to the right angle gearbox (1) to the steering unit (2).
When driving straight forward the steering unit (2) delivers equal power to both output shafts (3). Pressure on
either steering lever slows or stops the right or left brake drum, inside the center steering unit (2), and reduces
the speed of the right or left output shaft (3). By slowing down one side you increase the speed of the other and
the carrier will turn in the direction of the applied brake.
Equal pressure on both steering levers applies to both brakes and slows or stops the earner.
The differential overheat switch (4) is connected to a warning light in drivers compartment. When warning
light comes on it means oil temperature is too high.
