New Cat 320 GX and 323 GX Excavators deliver low maintenance and owning costs, increased fuel efficiency, and reliable performance


Reliable performance at a lower cost are the hallmarks of the new Cat ® 320 GX and 323 GX Hydraulic Excavators. The new excavators feature classic Cat D Series quality coupled with modern upgrades, such as a high-performance hydraulic system and modern controls. Along with the enhanced 320 and 323 and standard 320 GC and 323 GC models, the new GX excavators give contractors even more choices to meet their needs.

Designed to meet a range of customer needs from maximum productivity to low cost-per-ton operation, the new GX models offer lower fuel consumption, reduced maintenance costs, and a low initial purchase price compared to Cat GC models for a fast payback. The 320 GX and 323 GX are up to 15% more fuel efficient than the 320D2 GC and 320D2 L in similar applications.

An electronically controlled valve precisely directs hydraulic power where and when it is needed, boosting productivity. Maintaining the reliability and durability customers have come to expect from Cat excavators, the new GX series offer a lower initial purchase price than the other models but with more advanced features.

The choice of Power and Smart modes allows operators to manage fuel consumption. Power mode provides full-time maximum output and productivity, while Smart mode automatically matches engine and hydraulic power to digging conditions to conserve fuel without impacting production. Automatic Engine Control (AEC) reduces engine speed when the machine is stationary to minimize fuel consumption.

Easy to maintain

These new excavator models benefit from the latest technical enhancements to reduce maintenance costs by up to 20% compared to the 320D2 GC and 320D2 L. Design improvements significantly extend maintenance intervals and provide easy access to consolidated filters. Hydraulic, air, and fuel filters feature increased capacity for longer life.

Service intervals for fuel filters extend from 500 to 1,000 hours, while the new hydraulic oil filter improves filtration performance and extends replacement intervals from 2,000 to 3,000 hours. Auto warm-up expedites hydraulic warming in cold temperatures to help improve component life.

The new 320 GX and 323 GX excavators feature grease sealed between track pins and bushings to deliver reliable undercarriage operation. Offering durable, field-proven designs with standard J-tips, multiple bucket designs and capacities are available to meet contractors’ specific application need. Customers in certain regions can equip the buckets with optional Advansys™ tips that retain sharpness longer and can be quickly changed using a lug wrench.

Operating efficiency and safety

A push of a button starts the new 320 GX and 323 GX excavators. The new high-resolution, 203-mm (8-in) touchscreen monitor allows operators to quickly navigate most machine settings, including joystick pattern and response. Operator ID allows operators to select power mode, joystick pattern and joystick response and restores them at login for a quick return to work.

The GX cab design reduces operator effort. Featuring a seat that adjusts to accommodate operators of all sizes, machine controls are positioned in front to eliminate twisting and turning. Standard automatic climate control improves operator comfort, while cab sealing, pressurization, and a fresh air filter work to reduce noise and improve overall air quality. Large glass and narrow cab pillars enhance visibility into the trench, and an optional rearview camera further improves visibility. Convenience features include an integrated radio, built-in USB and auxiliary port for connecting and charging devices, and a 24V DC outlet for faster charging.

The GX excavators’ keyless push-button start and Operator ID code help to prevent machine theft. Ground-level access to filters, drains, and scheduled oil sampling ports makes routine maintenance easy and safe. Handrails, serrated steps, and anti-skid surfaces with recessed bolts make getting in, out, and up the excavator trouble free. The tool/storage box, fuel door, hydraulic oil fill, and fuel drain compartment are lockable for added security.

Standard Product Link™ telematics improves overall GX excavator efficiency by automatically and accurately collecting machine information, including location, hours, fuel usage, idle time, maintenance alerts, diagnostic codes, and machine health — all viewable online through web and mobile applications. My.cat.com and VisionLink ® provide online access to Product Link data, which allows operators to make informed decisions that help
increase productivity, lower costs, simplify maintenance, and improve jobsite safety and security.
