Engine
Built for power, reliability, economy and low emissions. Meeting regulations... Exceeding expectations.
Performance. The Cat C7 engine with ACERT Technology offers more
engine power, and runs at lower speeds for better fuel efficiency and reduced wear. The 329D is available with two engine power versions:
–Standard power (140 kW)
–Optional High power (152 kW)
Power Management. Optimal machine performance for each type of application. The operator can change the engine
power on the monitor from standard to high. The high power mode is
recommended for extremely productive areas and for hard digging applications.
Automatic Engine Speed Control.
The two-stage, one-touch control maximizes fuel efficiency and reduces sound levels.
Engine Controller. ADEM™ A4 (Advanced Diesel Engine Management) electronic control module manages fuel delivery to get the best performance per liter of fuel. The controller uses sensors in fuel, air intake, exhaust and cooling systems and 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.
Fuel Delivery. The Cat C7 features electronic controls that govern the mechanically actuated unit 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. To reduce fan noise, the cooling fan is driven from a viscous clutch which is electrically controlled by the machine ECM. It calculates optimum fan speed based on the target engine speed, coolant temperature, hydraulic oil temperature and actual fan speed. The Cat C7 delivers 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.
Environmentally Responsible Design
Caterpillar machines not only help you build a better world, they help maintain and preserve the fragile environment.
Emissions. The Cat C7 with ACERT Technology introduces a series of evolutionary, incremental improvements that provide breakthrough engine technology built on systems and components developed by Caterpillar with proven reliability. The technology capitalizes on Cat expertise in four core engine systems: fuel, air, electronics and after treatment. By combining ACERT Technology with the new Economy Mode, customers can balance the demands of performance and fuel economy to suit their requirements and application. ACERT engines meet EC Stage IIIA emissions regulation.
Fewer Leaks and Spills. Engine oil and encapsulated hydraulic oil filters are positioned vertically and are easy to reach to minimize spillage. Service intervals are extended to reduce the times fluids are changed and handled.
Hydraulic oil service interval can be extended to 4000 hours with the S•O•S program.
In addition to the S•O•S program fine filtration system attachment extends the service interval to 5000 hours.
Cat Extended Life Coolant extends service to 6000 h, less need for fluid disposal.
The hydraulic system is compatible with Cat HEES hydraulic bio-oil for ecologically sensitive applications.

Hydraulics
Cat hydraulics deliver power and precise control to keep material moving.
Component Layout. The 329D 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, which 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.
Heavy Lift Mode. Maximizing lifting performance and boosting the lifting capability. Heavy loads can be easily moved in the full working range of the machine maintaining excellent stability.
Hydraulic Cross Sensing System. The hydraulic cross sensing system utilizes each of two hydraulic pumps to 100%, under all operating conditions. This improves productivity with faster implement speeds and quicker, stronger pivot turns.
Pilot System. The pilot pump is independent from the main pumps and controls the front linkage, swing and travel operations.
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.
Electronic Control System.
Ten hydraulic pump flow and pressure settings can be preset, eliminating the need to adjust the hydraulics each time a tool is changed.
Auxiliary Valve. The auxiliary valve is standard. Control circuits are optional, allowing for operation of high and medium pressure tools such as shears, grapples, hammers, pulverizers, etc.
Hydraulic Cylinder Snubbers.
Located at the rod-end of the boom cylinders and both ends of the stick cylinders to cushion shocks while reducing sound levels and extending component life.
SmartBoom. Reduces stress and vibrations transmitted to the machine and provides a more comfortable environment.
Rock Scraping. Scraping rock and finishing work is easy and fast. SmartBoom simplifies the task and allows the operator to concentrate on stick and bucket, while boom freely goes up and down without using pump flow.
Hammer Work. The front parts automatically follow the hammer while penetrating the rock. Blank shots or excessive force on the hammer are avoided resulting in longer life for the hammer and the machine. Similar advantages with vibratory plates.
Truck Loading. Loading trucks from a bench is more productive and fuel efficient as the return cycle is reduced while the boom down function does not require pump flow.

Operator Station
Designed for simple, easy operation and comfort, the 329D allows the operator to focus on production.
Operator Station. The workstation is spacious, quiet and comfortable, assuring high productivity during a long workday. The air conditioner and attachment switches are conveniently located on the right-hand wall, and the key switch and throttle dial are on the right-hand console. The monitor is easy to see and maximizes visibility.
Seat. An optional air suspension seat is available in the 329D. The standard and optional seats provide 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.
Climate Control. Positive filtered ventilation with a pressurized cab is standard. Fresh air or re-circulated air can be selected with a switch on the right console.
Hydraulic Activation Control Lever.
For added safety, this lever must be in
the operate position to activate the machine control functions.
Controls. The 329D uses pilot operated control levers, positioned so the operator can operate with arms on the armrests. The vertical stroke is longer than the horizontal, reducing operator fatigue. The control lever grips are shaped to fit into the operator’s hands. The horn switch and one-touch low idle switch are positioned on the left and right grip.
Implement Controls. Easy to handle joysticks with integrated push buttons and sliding switches control all implement and swing functions. The sliding switches provide modulated control for hydromechanical tools and are designed to increase operator comfort and reduce operator fatigue.
Skylight. A unique large polycarbonate skylight provides very good upward visibility, especially useful in above ground applications.
Windows. To maximize visibility, all glass is affixed directly to the cab
eliminating the use of window frames. Choice of fixed or easy-to-open split front windshield meet operator preference and application conditions.
50/50 split front windshield allows both upper and lower portions to be stored in an overhead position.
70/30 split front windshield stores the upper portion above the operator. The lower front windshield features a rounded design to maximize downward visibility and improves wiper coverage.
Both openable versions feature
a one-touch action release system.
The fixed front windshield is available in standard duty laminated glass or high impact resistant laminated glass.
Wiper. Designed to maximize visibility in poor weather conditions. The parallel wiper system covers almost the complete front window without leaving unwiped areas in the immediate line of sight of the operator.
Cab Exterior. The exterior design uses thick steel tubing along the bottom perimeter of the cab, improving the resistance of fatigue and vibration. This design allows the FOGS to be bolted directly to the cab, at the factory or as an attachment later, enabling the machine to meet specifications and job site requirements.
