FAN A ND BRAK E HYDRAULIC SYSTEM
The fan and brake pump (25) is located on the front gear train of the engine, on the right side of the machine. The fan and brake pump provides oil flow for the electronic demand fan systemand the brake hydraulic system. The outlet pressure tap (AA) is located on the fan and brake pump. Also located on the engine on the right side of the machine is the fan control and brake accumulator charging valve (30). The fan pump load sense pressure tap (HH) is located above the brake charging valve.
