Note (1)

Net power advertised is the power available at the flywheel when the engine is equipped with fan, air intake system, exhaust system and alternator with engine speed at 1,800 rpm. Advertised power is tested per the specified standard in effect at the time of manufacture.

Note (2)

¹Cat engines are compatible with diesel fuel blended with the following lower-carbon intensity fuels** up to: 100% biodiesel FAME (fatty acid methyl ester)* or 100% renewable diesel, HVO (hydrotreated vegetable oil) and GTL (gas-to-liquid) fuels. Refer to guidelines for successful application. Please consult your Cat dealer or “Caterpillar Machine Fluids Recommendations” (SEBU6250) for details. *For use of blends higher than 20% biodiesel, consult your Cat dealer. **Tailpipe greenhouse gas emissions from lower-carbon intensity fuels are essentially the same as traditional fuels.

Cab Monitor Improvements

Continuously improved user interface allows for intuitive navigation, minimizing performance interruption with the easy-to-use touchscreen menu.
Identify apps quickly with a grid list view, abbreviated app names, and categorized menu options.
A notification center keeps important information visible to the operator, and displays messages without shrinking the camera view.
Color coded notifications set critical messages apart from the rest.
Use the in-monitor QR code to learn about machine and technology features through a full suite of “how-to” videos.

Not all features are available in all regions. Please check with your local Cat dealer for specific offering availability in your area. Build Number: 07G

The C7.1 engine can run on biodiesel up to B20 and emits equivalent to U.S. EPA Tier 3 and EU Stage IIIA.
Use up to 25% less fuel than the 320D2 to keep you moving and productive on the job site.
The advanced hydraulic system provides the optimum balance of power and efficiency while giving you the control you need for precise digging requirements.
Valve priority puts hydraulic pressure and flow where you command it to go for fast light- to medium-load cycle times.
Match the excavator to the job with two power modes; let Smartmode automatically match engine and hydraulic power to digging conditions.
Auxiliary hydraulic options give you the versatility to use a wide range of Cat attachments.
Lose less energy and reduce fuel consumption with the positive flow control pump. The pump flow adjusts automatically based on valve priority.
Advansys™ bucket tips increase penetration and improve cycle times. Tip changes can be done quickly with a simple lug wrench instead of a hammer or special tool, improving safety and uptime. Only available on HD buckets.

Work up to 3000 m (9,840 ft) above sea level without de-rating.
Don’t let the temperature stop you from working. The 323 GC has a standard high-ambient temperature capability of 52° C (°F) and cold start capability of –18° C (0° F).
Auto warm up speeds up hydraulic oil warming in cold temperatures and helps prolong the life of components.
Two levels of fuel filtration protect the engine from dirty diesel fuel.
Grease sealed between track pins and bushings reduces travel noise and prevents debris from entering to increase undercarriage life.
The track guiding guard helps keep the excavator track aligned when traveling and working on slopes.
The sloped track frame prevents mud and debris accumulation, helping reduce the risk of track damage.

The cab has a wide seat that adjusts for operators of all sizes.
Control the excavator comfortably with easy-to-reach controls alllocated in front of you.
Standard automatic climate control keeps you at the right temperature all shift long.
Feel more comfortable in the cab while you work with reduced cab vibrations from advanced viscous mounts.
Stow your gear with plenty of in-cab storage beneath and behind the seat, and in the consoles. A cup holder, document holder, bottle holder, and coat hook are also provided.
Use the USB ports and Bluetooth® technology to connect to personal devices.

Start the engine with the push button, a Bluetooth® key fob or the unique Operator ID function.
Program your power mode and joystick preferences using Operator ID; the excavator will remember what you set each time you go to work.
Navigate quickly on the standard high-resolution 203 mm (8 in) touchscreen monitor or with the aid of the jog dial control.
Use the in-monitor QR code to learn about machine and technology features through a full suite of “how-to” videos.
Protect your hammer tool from overheating and rapid wear. Auto hammer stop warns you after 15 seconds of continuous firing and then automatically shuts it off after 30 seconds - all to extend the tool’s service life.
Not sure how a function works or how to maintain the excavator? Always have the operator’s manual at your fingertips in the touchscreen monitor.
Find the tool you need – even if it’s hidden beneath overgrowth or debris. Search with your cell phone for any work tool equipped with Cat asset tracking devices up to a range of 60 m (200 ft).

Expect up to 25% less maintenance cost than the 320D2 (savings calculated over 12,000 machine hours).
Do all daily maintenance at ground level.
Boost productivity with proactive service reminders. The integrated vehicle health management system alerts the operator with step-by-step service guidance along with parts needed so you don't experience any unnecessary downtime..
Check engine oil level quickly and safely with the ground-level engine oil dipstick; fill and check engine oil on top of the machine with a conveniently located second dipstick.
Track your excavator’s filter life and maintenance intervals via the in-cab monitor.
Using Cat genuine oil and filters and doing your typical S∙O∙S^SM monitoring will double the current service interval to 1,000 hours, giving you greater uptime to do more work.
Expect the air intake filter with integrated precleaner to last up to 1,000 hours in certain applications – a 100% increase over the previous filter.
The latest hydraulic oil filter provides improved filtration performance, anti-drain valves to keep oil clean when the filter isreplaced, and longer life with a 3,000 hour replacement interval – 50% longer than previous filter designs.
High-efficiency cooling fans run only when needed; you can program intervals so they automatically reverse to keep cores clean without interrupting your work.
S·O·S ports are on ground level, simplifying maintenance and allowing for quick, easy extraction of fluid samples for analysis.

Access 100% of daily maintenance points from ground level – no need for you to climb on top of the excavator.
Keep your excavator secure with Operator ID. Use your PIN code on the monitor to enable the push button starting feature.
The standard ROPS cab meets ISO 12117-2:2008 requirements.
Enjoy great visibility into the trench, in each swing direction, and behind you with the help of smaller cab pillars, larger windows, and a flat engine hood design. A rearview camera is standard, and a right-side-view mirror is available.
The right service platform design provides easy, safe, and quick access to upper service platform; the service platform steps use anti-skid punch plate to prevent slipping.
The standard hydraulic lockout lever isolates all hydraulic and travel functions in the lowered position.
Ground-level shut-off switch stops all fuel to the engine when activated and shuts down the machine.
Make service work easier and safer with optional inspection lighting. With the flip of a switch, lights will illuminate the engine, pump, battery, and radiator compartments to enhance visibility.
Enhance jobsite safety. Add a swing alarm to alert people when you're rotating from trench to stockpile and back again.
