Power Train
The Cat® C7 has exceptional power and fuel efficiency unmatched in the industry for consistently high performance in both forestry and millyard applications.
Cat C7 ACERT™
The Cat® C7 with ACERT™ Technology gives the 324D FM exceptional power and fuel efficiency unmatched in the industry, and provides high performance in all forestry applications. The C7 meets U.S. EPA emissions requirements.Performance
The 324D FM is equipped with the C7 ACERT engine, which provides 12% more horsepower as compared to the previous 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 and hydraulic oil temperature. 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 engine mounts are rubber-isolating mounts matched with the engine package. Further noise reduction has been achieved through design changes to the isolated top cover, oil pan, multiple injection strategy, insulated timing cover, sculpted crankcase and gear train refinements.Hydraulics
Cat® hydraulics provide the power and control needed for a variety of applications.
Component Layout
The 324D FM hydraulic system and component locations have been designed to provide a high level of system efficiency. 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.Operator Comfort
The purpose built forestry cab interior layout maximizes operator space, provides exceptional comfort, provides excellent sightlines and reduces operator fatigue.
Operator Station
The workstation is spacious, quiet and comfortable, assuring high productivity during a long work day. Controls, joysticks and an ergonomically designed seat reduces operator fatigue.Pre-Start Check
Prior to starting the machine, the system will check for low fluid levels for the engine oil, hydraulic oil and engine coolant and warn the operator through the monitor in the event display area.Climate Control
Positive filtered ventilation, a pressurized cab with bi-level air conditioner, heater and defroster keep operator comfortable in all types of weather conditions. Cab also has a forced air fan and a large fresh air window.Monitor
The monitor is a full color 400 X 234 pixels Liquid Crystal Display (LCD) graphic display. The monitor angle can be adjusted to minimize sun glare and has the capability of displaying information in 27 different languages.Gauge Display
Three analog gauges, fuel level, hydraulic oil temperature and coolant temperature, are displayed in this area.Event Display
Machine information is displayed in this area with the icon and language.Multi-Information Display
This area is reserved for displaying various information which is convenient for the operator. The “Cat” logo is displayed when no information is available to be displayed.Seat
Air ride seat provides a variety of adjustments to suit the operator’s size and weight including fore/aft, height and weight. Wide adjustable armrests and a retractable seat belt are also included.Joystick Control
Joystick controls have low lever effort and are designed to match the operator’s natural wrist and arm position. The operator can operate joystick controls with an arm on the armrest and the horizontal and vertical strokes have been designed to reduce operator fatigue. Exclusive proportional control and push buttons are programmable to operator personal preferences, allowing maximum productivity.Hydraulic Activation Control Lever
For added safety, this lever must be in the operate position to activate the machine control functions.Console
Consoles feature a simple, functional design to reduce operator fatigue, ease of switch operation and excellent visibility.Skylight
An enlarged skylight with sunshade provides excellent upwards visibility.Viewing
Cab design optimizes post structures, and scratch-resistant polycarbonate window placement to provide excellent operator visibility to front, sides and rear. Forestry cab is designed with heavy-duty guarding, meeting all ROPS/FOPS/OPS/FOGS/TOPS and CB requirements. Windshield wipers are standard equipment on the FM cab.Structures
