Case CX380E Hydraulic Excavator: E-Series Tier 4 Final 38-Ton Production Machine
The Case CX380E is a 38-ton class E-Series hydraulic excavator - the newest heavy production excavator in the Case full-size lineup. Tier 4 Final emissions, common-rail diesel, load-sensing hydraulics, and a steel-track undercarriage built for general site work, utility installation, and quarry duty.
Where the CX380E fits in the Case excavator line
The CX380E is a 38-ton class E-Series excavator sitting between the CX370D and the CX460 in Case’s full-size excavator lineup. The E-Series brought Tier 4 Final emissions to the heavy end of the Case excavator family, paired with refined load-sensing hydraulics and electrohydraulic main control valves.

Engine, hydraulics, and drivetrain
The CX380E runs a Tier 4 Final diesel with common-rail injection, cooled EGR, DPF, and SCR aftertreatment with DEF dosing. The main hydraulic circuit is a load-sensing piston pump arrangement feeding boom, dipper, bucket, swing, and propel through electrohydraulic control valves. Travel is hydrostatic dual-path through final drives onto a steel-track undercarriage.
The hydraulic system on a 38-ton class production excavator is the heart of the machine - cylinder seal kits, main pump rebuild parts, swing motor service, and electrohydraulic valve components are the highest-volume long-life service items. The Tier 4 Final aftertreatment adds DPF service intervals, DEF tank refills, NOx sensor service, and SCR catalyst monitoring to the maintenance program.
Common service items on the CX380E
- Engine internals: Tier 4 Final diesel pistons, rings, sleeves, head gaskets, bearings.
- Aftertreatment: DPF service and cleaning, DEF tank and dosing module, SCR catalyst, EGR cooler service, NOx sensors.
- Fuel system: Common-rail injectors, high-pressure fuel pump, lift pump, primary and secondary filters with tight water-separator standards.
- Cooling system: Radiator, water pump, thermostat, fan, charge-air cooler, hoses, belts.
- Hydraulic system: Boom, dipper, bucket, and swing cylinder seal kits, main pump rebuild kits, electrohydraulic control valves, hoses.
- Boom and dipper: Pin and bushing service at every joint, bucket pins, thumb attachment hardware, quick coupler service.
- Undercarriage: Steel track chains and shoes, rollers, idlers, drive sprockets, recoil springs.
- Swing system: Swing motor and reduction gear, swing bearing, swing brake.
- Electrical / ECU: Engine ECU, instrument cluster, sensors, harness, telematics module on equipped units.
- Cab glass and wiper: KHN16820 24-inch wiper blade, KHN3046 front lower glass, and KHN2632 front upper glass cross-fit across Case and Link-Belt excavators.
- Operator station: Seat, joystick controls, pedal linkage, instrument panel, cab HVAC.

Request a PartWhat to verify before ordering
- Machine serial number. Confirm the serial on the CX380E before ordering year-specific parts. The plate is on the RH lower cab frame, below the windshield.
- Engine serial. Engine internal parts must match the engine serial.
- Hydraulic cylinder bore. Cylinder seal kit fit depends on bore dimension - measure before ordering.
- Tier 4 emissions revision. DPF and DEF/SCR components saw revisions across the production run - confirm by serial.
- Engine ECU calibration. Common-rail injectors and ECU sensors are calibrated to specific build years.
- Bucket and quick coupler. Quick-coupler interface varies - confirm before ordering attachment-side hardware.
Why the CX380E still earns a paycheck
The Case CX380E is a 38-ton class production excavator - general site work, utility installation, residential and commercial earthmoving, and mining and quarry work depending on configuration. The E-Series brought the Case full-size excavator family to current emissions while keeping the load-sensing hydraulic architecture customers know.
Maintenance priorities on a CX380E: clean fuel and tight water separation for common-rail injection, DPF regen tracking, DEF quality, hydraulic oil condition, swing-bearing lubrication, steel-track tension and undercarriage wear monitoring, and pin and bushing service. Broken Tractor maintains parts coverage across the Case excavator family.
