Reliable Cat C7.1 Engine
The Cat C7.1 engine has been designed to meet U.S. EPA Tier 3 and EU Stage III emission regulations. The C7.1 engine incorporates proven, robust components and precision manufacturing you can count on for reliable and efficient operation. This is a proven engine that boasts improved reliability, as it’s less sensitive to low quality fuel and also delivers reduced fuel consumption. 13% fuel consumption reduction vs. 324D is with HHP mode.
Automatic Engine Control
Automatic engine control is activated during no-load or light-load conditions which reduces engine speed to minimize fuel consumption.
The radially sealed 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 reliability to the fuel injection system components. The primary filter and the secondary twin filters improve filtration efficiency and machine robustness.
Ergonomically designed to keep you comfortable and productive all day long.
ROPS Certified Operator Station
The 326D2 L features a ROPS (Roll Over Protective Structure) compliant cab structure as standard which meets OSHA and MSHA sound requirements. This design also allows for a Falling Object Guard System (FOGS) or front windshield guard to be bolted directly to the cab, either at the factory or in the field, enabling the machine to meet all job site requirements.
More glass versus previous non-ROPS cab to improve visibility
More interior head room space
Improved cab pressurization
ROPS cab air filter accessible at ground level
The new monitor on the 326D2 L features a 40 percent larger screen with four times increased resolution display. The LCD monitor is equipped with a warning lamp and buzzer for critical engine oil pressure, coolant temperature and oil temperature. Programmable in up to 42 languages to meet today’s diverse workforce, the monitor clearly displays critical information needed to operate efficiently and effectively. Filters and fluid change intervals are available in the main menu which also projects the image from the optional rearview camera, further enhancing your job site safety and productivity.
The suspension seat provides 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.
Operators can adjust the right and left joysticks for individual preferences, helping them become 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 326D2 L offers positive filtered ventilation with a pressurized cab. Fresh air or recirculated 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 operator comfort. Thick steel tubing along the bottom perimeter of the cab improves resistance to fatigue and vibration.
Cat hydraulics deliver power and precise control to keep material moving.
Hydraulic system pressure from the two-hydraulic pump system delivers the best in class digging performance and productivity.
An independent pilot pump enables smooth, precise control for the front linkage, swing, and travel operations.
Hydraulic Activation Control Lever
With the hydraulic activation lever in the neutral position, all front linkage, swing, and travel functions are isolated.
The 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, reducing friction loss and pressure drops.
Hydraulic Cross-Sensing System
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.
Auxiliary Hydraulic Valve
Control circuits are available as attachments to improve versatility. They allow operation of high- and medium-pressure tools such as shears, grapples, hammers, pulverizers, multi-processors, and vibratory plate compactors.
Optioinal Undercarriage and Structures
Strong and durable, all you expect from Cat excavators.
Up to 95% of the structural welds on a Cat Excavator are completed by robots. Robotic welds achieve over three times the penetration of manual welds.
Carbody Design and Track Roller Frames
X-shaped, box-section carbody provides excellent resistance to torsional bending. Robot-welded track roller frames are press-formed, pentagonal units which deliver exceptional strength and service life.
Rollers and Idlers
Sealed and lubricated track rollers, carrier rollers, and idlers provide excellent service life to keep the machine in the field longer.
The long undercarriage (L) maximizes stability and lift capacity. This long, wide and sturdy undercarriage offers a very stable work platform.
The upper frame includes reinforced mountings to support the ROPS cab, the lower frame is reinforced to increase component durability.
The 326D2 L track links are assembled and sealed with grease to decrease internal bushing wear, reduce travel noise and extend service life lowering operating costs.
The 4.8 mt (5.2 t) standard counterweight makes a better choice for heavy lifting with long undercarriage. Counterweights are bolted directly to the main frame for extra rigidity.
Service and Maintenance
Simplified service and maintenance features save you time and money.
The design and layout of the 326D2 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 left side service compartment features the battery disconnect switch, electrical circuit breakers, air conditioning condenser core. The air filter features a double-element construction for superior cleaning efficiency. When the air cleaner plugs, a warning is displayed on the monitor screen inside the cab.
A service door on the right side of the upper structure allows ground‑level access to the pump, pilot filter, and water separator with primary fuel filter.
The left rear service door allows easy access to the engine radiator, hydraulic oil cooler, air-to-air-aftercooler, second and third fuel filters, and fuel cooler. A reserve tank and drain cock are attached to the radiator for simplified maintenance.
Conveniently located grease blocks help you get lube in hard-to-reach places, making routine boom, stick, and bucket linkage maintenance quick and easy.
The engine radiator fan is completely enclosed by fine wire mesh, reducing the risk of an accident.
Anti-skid plate with countersunk bolts reduce trip hazards which covers top of storage box and upper structure to prevent accidents during maintenance.
Diagnostics and Monitoring
The 326D2 L is equipped with S∙O∙SSM ports to easily sample hydraulic and engine oil quality. Test ports are also conveniently located so you can test coolant and hydraulic pressure.
