  • The excavator uses up to 20 percent less fuel than the 320D2 GC in similar applications.
  • Match the excavator to the job using power modes; let Smart modeautomatically match engine and hydraulic power to your digging conditions.
  • 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.
  • Meets U.S. EPA Tier 3/EU Stage IIIA/China Nonroad Stage III/Brazil MAR-1 equivalent emission standards.
  • Add auxiliary hydraulics to do more work with a range of Cat attachments.
  • Product Link™ comes standard so you can remotely monitor machine health, location, hours, and fuel consumption on demand through the VisionLink® online interface.


  • Expect up to 15 percent less maintenance cost than the 320E (savings calculated over 12,000 machine hours).
  • Do all daily maintenance at ground level.
  • Check engine oil level quickly and safely with the new ground-levelengine oil dipstick; fill and check engine oil on top of the machinewith a conveniently located second dipstick.
  • Track your excavator’s filter life and maintenance intervals via thein-cab monitor.
  • No required maintenance on the Cat Clean Emissions Module.
  • Change all fuel filters at a synchronized 500 hours.
  • Expect the new air intake filter with precleaner to last up to 1,000 hours – a 100 percent increase over the previous filter.
  • The new hydraulic oil filter provides improved filtration performance,anti-drain valves to keep oil clean when the filter is replaced, and longer life with a 3,000 hour replacement interval – 50 percent longer than previous filter designs.
  • The new high-efficiency electric cooling fans only run when needed and reverse to keep cores free from debris.
  • S·O·S ports simplify maintenance and allow for quick, easy extraction of samples for fluid analysis.


  • Work up to 3000 m (9,840 ft) above sea level without de-rating.
  • Standard high-ambient temperature capability is 52º C (125º F) with cold start capability at –32º C (–25º F).
  • Auto warm up speeds up hydraulic oil warming in cold temperatures and helps prolong the life of components.
  • Three 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 center 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 risk of track damage.


  • Access 100 percent 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 pushbutton starting feature.
