Hydraulic HorsepowerHydraulic horsepower is the actual machine power available to do work through implements and work tools. It’s much more than just the engine power under the hood – it’s a core strength that differentiates Cat machines from other brands. In fact, hydraulic horsepower for the 336E increased from the previous series’ output due to pump and other system improvements. This translates into the new E Series moving more material in less time.
Main Control Valve and Auxiliary ValvesThe 336E uses a high-pressure system to tackle the toughest of work in short order. A new one-piece, cast-block, back-to-back main control valve features resized and reshaped oil passages to improve efficiency and serviceability; stackable auxiliary valve attachments mount on top of the main valve, which allows for auxiliary hydraulic lines and valve configurations to be simplified for greater reliability.
Return FilterThe return filter is a capsule-type design with a cartridge inside. Unlike many competitors’ offerings, the Cat cartridge features a handle to help remove and change without oil spillage or contamination. A sensor attached to the filter warns the operator if it is full or exceeds a certain pressure level.
Swing Priority CircuitThe swing priority circuit on the 336E uses a new electric valve that’s operated by the machine’s improved Electronic Control Module (ECM). Compared to using a hydraulic valve, an electric valve allows for more finely tuned control, which is critical during material loading.
Electric Boom Regeneration ValveA new electric boom regeneration valve minimizes pump flow when the boom lowers down, which improves fuel economy. It is optimized for any dial speed setting being used by the operator, which in turn aids controllability and enhances component durability.
Stick Regeneration CircuitThe 336E regenerates the flow of oil from the rod end of the stick cylinder to the head end of the stick cylinder during low-load, stick-in operation – an approach that saves energy and expense.

SeatsA new seat range includes mechanical, air suspension, heated, and air cooled options. Each option includes a reclining back, upper and lower seat slide adjustments, and height and tilt angle adjustments to meet operator needs for comfort and productivity.
ControlsThe right and left joystick consoles can be adjusted to meet the operator’s desired preference, making him (or her) more comfortable and productive during the course of a day.
With the touch of the button, one-touch idle reduces engine speed to help save fuel; touch it again or move the joystick and the machine returns to normal operating level.
The optional heavy lift mode increases machine system pressure to improve lift – a nice benefit in certain situations. Heavy lift mode also reduces engine speed and pump flow in order to improve controllability.
MonitorThe 336E is equipped with a new LCD (Liquid Crystal Display) monitor that’s 40% bigger than the previous model’s with higher resolution for better visibility. In addition to an improved keypad and added functionality, it is programmable to provide information in a choice of 42 languages to support today’s diverse workforce.
A new “Engine Shutdown Setting” accessible through the monitor allows owners and operators to specify how long the machine should idle before shutting down the engine, which can save significant amounts of fuel.
In addition, the monitor serves as a display for the optional rearview camera. Up to two different camera images can be displayed on the screen.
MP3-Ready Radio and Power SupplyThe standard radio is equipped with a new auxiliary audio port for MP3 players. Two 12-volt power supply sockets are located near key storage areas for charging.
StorageStorage spaces are located in the front, rear, and side consoles. New space near the auxiliary power supply holds MP3 players and cell phones. The drink holder accommodates large mugs with handles, and a new shelf behind the seat stores large lunch or toolboxes.
Automatic Climate ControlThe climate control system features five air outlets with positive filtered ventilation, which makes working in the heat and cold much more pleasant.

Cat® C9.3 ACERT™ EngineThe C9.3 ACERT engine delivers more horsepower using less fuel than the previous series engine.
Emissions SolutionThe C9.3 ACERT engine is equipped to meet current U.S. Tier 4 Interim regulations. Driven by customer input, Caterpillar’s aftertreatment regeneration solution ensures the machine works as normal with no operator intervention needed.
The machine comes with two programmable modes of operation: automatic and manual regeneration.
In automatic mode, the machine starts the regeneration process once the filtering system reaches a certain level and conditions are optimal. The system will not interrupt the work process and can regenerate during machine operation.
Manual mode enables the operator to override the automatic mode. With a touch of a button (1) inside the cab, this mode allows the operator to move the machine from flammable or heat-restricted areas before initiating the regeneration process.
Bio Diesel-Ready Fuel SystemThe C9.3 ACERT engine is equipped with a high-pressure common rail fuel system that includes a new electric priming pump and three-layer fuel hose to allow the use of bio fuel up to B20 (bio fuel 20% mixture).
Cooling SystemThe high-ambient cooling system features a fixed-speed fan and a side-by-side-mounted radiator and oil and air coolers for easy cleaning.
Speed and Power ControlThe new E Series features isochronous speed control to maintain a constant speed – regardless of load – to improve fuel economy. Three different power modes are offered: high power, standard power, and economy power. The operator can easily change between modes through the monitor or console switch to meet the needs for the job at hand – all to help manage and conserve fuel.

Regardless of choice, counterweights are bolted directly to the main frame using four M36 bolts for rigidity and feature an integrated housing for the new rearview camera option.
Structures and Undercarriage
Booms and SticksThe 336E is offered with a range of booms and sticks. Each is built with internal baffle plates and stress-relieved for added durability, and each undergoes ultrasound inspection to ensure quality and reliability. Large box-section structures with thick, multi-plate fabrications, castings, and forgings are used in high-stress areas such as the boom nose, boom foot, boom cylinder, and stick foot to improve durability. Also, the boom nose pin retention method is a captured flag design for enhanced durability.
SelectionsThere are three boom and stick options: HD, ES, and ME. Sticks match the HD, ES, and ME boom descriptions and applications below.
HD = Heavy Duty. This type of boom is best used for reach applications where conditions are optimal such as excavating basements, trenching for utility lines, and sewer applications. The combination of boom and stick is matched to the digging conditions.
ES = Extreme Service. This type of boom is best used for demolition applications or extreme applications where stress loads on the boom are increased. It should be used for demanding, harsh applications such as 100% rock and extensive hammer use.
ME = Mass Excavation. This type of boom is best used for quarry and other demanding applications. Used for high-volume production and loading, the ME front provides higher digging forces due to the geometry of the boom and stick. Bucket linkage and cylinders are more durable for excellent productivity in harsh applications.

Electric Boom and Stick Regeneration ValveThe 336E features unique electric boom and stick regeneration valves. The valves use gravity during typical “boom down” or “stick in” operations to regenerate flow of oil from the head end of the cylinder to the rod end of the cylinder instead of sending it all the way back to the hydraulic tank. This distinct Caterpillar solution increases efficiency and reduces cycle times and pressure loss for higher productivity and lower fuel costs.
Cat® Grade Control Depth and SlopeThis optional system (1) combines traditional machine control and guidance with standard factory-installed and calibrated components, making the system ready to go to work the moment it leaves the factory. The system utilizes internal front linkage sensors – well protected from the harsh working environment – to give operators real-time bucket tip position information, which minimizes the need and cost for traditional grade checking and improves job site safety. It also helps the operator complete jobs in fewer cycles, which means less fuel use. Cat dealers can upgrade the system to full three-dimensional control by adding proven Cat AccuGrade™ positioning technologies, including GPS and Universal Total Station (UTS).
Cat Product Link*This deeply integrated machine monitoring system is designed to help customers improve their overall fleet management effectiveness. Events and diagnostic codes as well as hours, fuel consumption, idle time, machine location, and other detailed information are transmitted to a secure web based application called VisionLink™, which uses powerful tools to communicate to users and dealers.
*Product Link licensing is not available in all areas. Please consult your Cat dealer for availability.
