Cat C6.4 ACERT.The Cat C6.4 withACERT Technology gives the320D FM exceptional power and fuelefficiency unmatched in the industry.The C6.4 meets U.S. EPA Tier 3emissions requirements. The forestrydesigned hydraulics give the 320D FMexceptional power, efficiency and

controllability unequaled in the industryfor consistently high performance inall forestry applications.

Performance. The 320D FM is equippedwith the C6.4 ACERT engine, whichprovides 7% more horsepower ascompared to the Cat 3066 T engine.

Automatic Engine Speed Control.The two-stage, one-touch controlmaximizes fuel efficiency and reducessound levels.

ADEM A4 Engine Controller.The ADEM A4 electronic controlmodule manages fuel delivery to get thebest performance per liter of fuel used.The engine management system providesflexible fuel mapping, allowing theengine to respond quickly to varyingapplication needs. It tracks engine and

machine conditions while keeping theengine operating at peak efficiency.

Electronic Control Module.The Electronic Control Module (ECM)works as the brain of the enginescontrol system, responding quickly tooperating variables to maximize engineefficiency. Fully integrated with sensorsin the engines fuel, air, coolant, andexhaust systems, the ECM stores andrelays information on conditions such asrpm, fuel consumption, and diagnostic

information.

Fuel Delivery. The Cat C6.4 ACERTfeatures electronic controls that governthe fuel injection system. Multiple

injection fuel delivery involves a highdegree of precision. Precisely shapingthe combustion cycle lowers combustionchamber temperatures, generatingfewer emissions and optimizing fuelcombustion. This translates into morework output for your fuel cost.

Cooling System. The cooling fanis directly driven from the engine.An optional programmable reversible fanallows for radiator blowout, to increaseservice intervals and to maintain engineoperational temperatures. The optimumfan speed is calculated based on thetarget engine speed, coolant temperature,hydraulic oil temperature and actual fanspeed. The Cat C6.4 ACERT delivereda completely new layout that separatesthe cooling system from the enginecompartment.

Air Cleaner. The radial seal air filterfeatures a double-layered filter core formore efficient filtration and is located ina compartment behind the cab. A warningis displayed on the monitor when dustaccumulates above a preset level.

Noise Reduction Technologies.The engine mounts are rubber-isolatingmounts matched with the enginepackage. Further noise reduction hasbeen achieved through design changesto the isolated top cover, oil pan,multiple injection strategy, insulatedtiming cover, sculpted crankcaseand gear train refinements.

Component Layout. The 320D FMhydraulic system and componentlocations have been designed to providea high level of system efficiency.The main pumps, control valves andhydraulic tank are located close togetherto allow for shorter tubes and linesbetween components that reduce frictionloss and pressure drops in the lines.The layout further provides greateroperator comfort by placing the radiatoron the cab side of the upper structure.This allows incoming air to enter theengine compartment from the operatorside and hot air and correspondingengine sound to exit on the oppositeside away from the operator. This reducesengine compartment heat and soundbeing transmitted to the operator.

Pilot System. The pilot pump isindependent from the main pumps andcontrols the front linkage, swing andtravel operations.

Hydraulic Cross Sensing System.The hydraulic cross sensing systemimproves productivity with fasterimplement speeds and quicker,stronger pivot turns.

Boom and Stick Regeneration Circuit.Boom and stick regeneration circuitsaves energy during boom-down andstick-in operation which increasesefficiency, reduces cycle times andpressure loss for higher productivity,lower operating costs and increasedfuel efficiency.

Fine Swing Control. Standard fine swingcontrol cushions start and stop for betterimplement control.

Controllability. The hydraulic systemoffers precise control to the 320D FMreducing operator fatigue, improvingoperator effectiveness and efficiency,which ultimately translates intoenhanced performance.

Auxiliary Hydraulic Valve. The auxiliaryvalve is standard on the 320D FM.Control Circuits are available asattachments, allowing for operationof high and medium pressure tools

such as grapples.Hydraulic Cylinder Snubbers.Snubbers are located at the rod-endof the boom cylinders and both endsof the stick cylinders to cushion shocks,reduce sound and increase cylinder life,increasing uptime and productivity.

Owning and Operating CostsCaterpillar Forest Machines provide the best value for your forestry and millyard applications.

ServiceabilitySimplified service and maintenance features save you time and money.

ACERT Technology Fuel Economy.Based on Caterpillartesting, the fuel economy of Cat engines with ACERTtechnology is 3 to 5 percent better than current competing

technologies. This fuel economy is directly related to thecomplete combustion of fuel due to the integration betweenthe electronic control that monitors conditions, the airmanagement system that controls air volume and the fuelinjection system that delivers just the right amount of fuelas needed.

Radiator Compartment. The radial air filter has a doublelayered filter core for more efficient filtration and is locatedin a compartment behind the cab. Easy access doors allowsfor easy, faster cleanout minimizing down time. Heavy-dutyscreen filters assembled on the door keep debris away fromthe radiator compartment, extending service intervals.
