HYDRAULIC SYSTEMS
REVERSIBLE FAN
The Reversible Fan is hydraulically driven
via the constant pitch fan hydraulic motor,
which in turn, is driven by the hydraulic
pump. The system’s hydraulic pump is driven
directly off engine-supplied PTO (power
take-off) to efficiently draw power
independent of engine speed. An electrically-
controlled proportional pressure control
valve (FDC - Fan Drive Control mounted to
pump) modulates fan speed depending on
machine’s cooling demand. On-demand
operator input controls the fan reversing
option to provide the operator the ability to
purge debris from the cooling package
shroud.
NOTE: The fan system reduces power and
fuel consumption of the engine when
full airflow is not required to keep the
engine cool.
To Activate the Reversible Fan
Refer to “Machine Display” provided in the
Cab Section
elsewhere in this manual for
complete operating instructions.
Before Starting the Engine
1. Ensure all hoses and wires are ade-
quately secured and routed away from
the fan operating area.
2. Ensure all tools have been removed
from the engine compartment, including
the top side of the radiator and inside of
the shroud before the fan guards are
installed. Obstacles in the path of rota-
tion can interfere with movement of the
fan and can result in damage to the fan
blades, fan hub, and radiator core.
