Cat C7 ACERT™. The Cat®C7 with
ACERT™ Technology gives the
324D FM exceptional power and fuel
efficiency unmatched in the industry.
The C7 meets U.S. EPA Tier 3 emissions
requirements. The forestry designed
hydraulics give the 324D FM exceptional
power, efficiency and controllability
unequaled in the industry for consistently
high performance in all forestry
applications.
Performance. The 324D FM is equipped
with the C7 ACERT engine, which
provides 12% more horsepower as
compared to the 3126B ATAAC
HEUI™ engine.
Automatic Engine Speed Control.
The two-stage, one-touch control
maximizes fuel efficiency and reduces
sound levels.
ADEM™ A4 Engine Controller.
The ADEM A4 electronic control module
manages fuel delivery to get the best
performance per liter of fuel used.
The engine management system provides
flexible fuel mapping, allowing the
engine to respond quickly to varying
application needs. It tracks engine and
machine conditions while keeping the
engine operating at peak efficiency.
Electronic Control Module.
The Electronic Control Module (ECM)
works as the “brain” of the engine’s
control system, responding quickly to
operating variables to maximize engine
efficiency. Fully integrated with sensors
in the engine’s fuel, air, coolant, and
exhaust systems, the ECM stores and
relays information on conditions such as
RPM, fuel consumption, and diagnostic
information.
Fuel Delivery. The Cat C7 ACERT
features electronic controls that govern
the fuel injection system. Multiple
injection fuel delivery involves a high
degree of precision. Precisely shaping
the combustion cycle lowers combustion
chamber temperatures, generating
fewer emissions and optimizing fuel
combustion. This translates into more
work output for your fuel cost.
Cooling System. The cooling fan
is directly driven from the engine.
An optional programmable reversible
fan allows for radiator blowout, to
increase service intervals and to maintain
engine operational temperatures.
The optimum fan speed is calculated
based on the target engine speed, coolant
temperature, hydraulic oil temperature
and actual fan speed. The Cat C7 ACERT
delivered a completely new layout that
separates the cooling system from the
engine compartment.
Air Cleaner. The radial seal air filter
features a double-layered filter core for
more efficient filtration and is located in
a compartment behind the cab. A warning
is displayed on the monitor when dust
accumulates above a preset level.
Noise Reduction Technologies.

The main pumps, control valves and
hydraulic tank are located close together
to allow for shorter tubes and lines
between components that reduce friction
loss and pressure drops in the lines.
The layout further provides greater
operator comfort by placing the radiator
on the cab side of the upper structure.
This allows incoming air to enter the
engine compartment from the operator
side and hot air and corresponding
engine sound to exit on the opposite
side away from the operator. This reduces
engine compartment heat and sound
being transmitted to the operator.
Pilot System. The pilot pump is
independent from the main pumps and
controls the front linkage, swing and
travel operations.
Hydraulic Cross Sensing System.
The hydraulic cross sensing system
improves productivity with faster
implement speeds and quicker, stronger
pivot turns.
Boom and Stick Regeneration Circuit.
Boom and stick regeneration circuit
saves energy during boom-down and
stick-in operation which increases
efficiency, reduces cycle times and
pressure loss for higher productivity,
lower operating costs and increased
fuel efficiency.
Fine Swing Control. Standard fine swing
control cushions start and stop for better
implement control.
Controllability. The hydraulic system
offers precise control to the 324D FM
reducing operator fatigue, improving
operator effectiveness and efficiency,
which ultimately translates into
enhanced performance.
Auxiliary hydraulic Valve. The auxiliary
valve is standard on the 324D FM.
Control Circuits are available as
attachments, allowing for operation
of high and medium pressure tools
such as grapples.
Hydraulic Cylinder Snubbers. Snubbers
are located at the rod-end of the boom
cylinders and both ends of the stick
cylinders to cushion shocks, reduce
sound and increase cylinder life,
increasing uptime and productivity.
