The hydraulic tank is a fabricated steel vessel at the left front of the machine. The tank contains the oil that is used to operate the brakes, the steering, the fan, and the body hoist systems.
The hydraulic tank has supply and return ports for the various machine systems. There is a suction port for the piston pump (brake, hoist, and fan). A suction port for the piston pump (hoist and steering). There is a return port for the pump case drain. Brake system oil is returned to the tank through the return port.
