The ergonomically-designed Roll Over Protective Structure (ROPS) compliant cab offers a spacious, quiet, and comfortable environment assuring high productivity during a long work day while meeting OSHA and MSHA sound requirements. All control switches are located on the right-hand and left-hand side consoles for more convenient access.
The new monitor is a full-color Liquid Crystal Display (LCD). Monitor is equipped with warning lamp and buzzer for critical engine oil pressure, coolant temperature and oil temperature. Filters and fluid change intervals are available in the main menu. It also projects the image from the optional rearview camera, further enhancing your job site safety and productivity. Compared to 323D L D Series monitor, the new monitor on 323D2 L has a 40% larger screen, with a four times increased resolution display. Information language capability increased from 28 to 42 languages to support today’s diverse workforce.
The air suspension seats provide a variety of adjustments to accommodate a wide range of operators. All seats include a reclining back, upper and lower seat slide adjustments, and height and tilt adjustments.
You can adjust the right and left joysticks for individual preferences, helping you be more comfortable, more productive, and more alert. Low-effort pilot-operated joystick controls are designed to match your natural wrist and arm position for maximum comfort and minimum fatigue.
The 323D2 L offers positive filtered ventilation with a pressurized cab. Fresh air or re-circulated air can be selected, which makes working in the heat and cold much more pleasant.
Cab Structure and Mounts
The cab shell is attached to the frame with viscous rubber cab mounts, which dampen vibrations and sound levels while enhancing your comfort. Thick steel tubing along the bottom perimeter of the cab improves resistance to fatigue and vibration.
To maximize visibility, all glass is affixed directly to the cab, eliminating window frames. The upper front windshield opens, closes, and stores on the roof with a one-touch action release system.
Count on reliable performance to meet your demanding needs all day long
Reliable Cat C7.1 Engine
The Cat C7.1 engine has been designed to meet Tier 3 and Stage III equivalent emission standards. The C7.1 engine incorporates proven, robust components and precision manufacturing you can count on for reliable and efficient operation. This proven engine boasts improved reliability as it’s less sensitive to low quality fuel, delivering better fuel consumption. An ECO mode feature helps reduce fuel consumption by up to 15 percent for fuel-conscious customers.
Automatic Engine Speed Control
Automatic engine speed control is activated during no-load or light-load conditions which reduces engine speed minimizing fuel consumption.
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.
The C7.1 engine features an improved filtration system to ensure good reliability to fuel injection system components. Intervals have been extended and the number of filters reduced to maximize your profit potential.
Move dirt, rock and debris with speed, precision and efficiency
The hydraulic cross-sensing system utilizes each of two hydraulic pumps to 100 percent of engine power under all operating conditions. This improves productivity with faster implement speeds and quicker, stronger pivot turns. Snubbers are 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. The hydraulic activation lever in the neutral position isolates all front linkage, swing, and travel functions for additional controllability and efficiency. Optional auxiliary control circuits allow operation of high- and medium-pressure tools such as shears, grapples, hammers, pulverizers, multi-processors, and vibratory plate compactors.
The 323D2 L 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.
Structures and Optional Undercarriage
Strong and durable, all you expect from Cat excavators
The long (L) wide and sturdy undercarriage maximizes stability and lift capacity. The X-shaped, box-section carbody provides excellent resistance to torsional bending. Robot-welded track roller frames are press-formed, pentagonal units to deliver exceptional strength and service life. Sealed and lubricated heavy-duty track rollers, carrier rollers, and idlers provide excellent service life to keep your machine in the field and working longer.
You can expect excellent quality, reliability and durability with the 323D2 L lower and upper frames. Both are built to handle a hard day’s work over and over again.

Safe, fast, and easy access
The design and layout of the 323D2 L was made with the service technician in mind. Most service locations are easily accessible at ground level to allow service and maintenance to get completed quickly and efficiently.
Air Filter Compartment
The air filter features a double-element construction for superior cleaning efficiency. When the air filter plugs, a warning is displayed on the cab monitor. Maintenance free batteries are standard along with a battery disconnect switch.
A service door on the right side of the upper structure allows ground-level access to the hydraulic pumps, hydraulic filters, engine oil filter, and fuel filters.
The left rear service door allows easy access to the engine radiator, hydraulic oil cooler, air-to-air aftercooler, and AC condenser. A reserve tank and drain cock are attached to the radiator for ground level maintenance.
A concentrated remote greasing block on the boom allows the greasing of hard-to-reach locations on the boom and stick.
The engine radiator fan is enclosed by a steel guard that provides maximum protection when carrying out routine service and maintenance.
Anti-skid plating covers the entire upper structure and storage box to prevent slipping during maintenance. Safety is further enhanced with the addition of countersunk bolts to reduce trip hazards.
Diagnostics and Monitoring
The 323D2 L is equipped with Scheduled Oil Sampling (S∙O∙SSM) ports for the hydraulic system, engine oil, and coolant. Standard hydraulic test ports enable a service technician to quickly and easily fault find in the event of service issue.
