Case CX180D Excavator: 2017–2022 18-Ton D-Series Excavator
The Case CX180D is an 18-ton class D-Series hydraulic excavator produced from 2017 into the early 2020s. It sits between the earlier CX180B and the newer CX190E in Case’s mid-class excavator lineup, running a Tier 4 Final diesel with DPF and SCR aftertreatment and a hydrostatic dual-path drivetrain.
Where the CX180D fits in the Case excavator line
The CX180D is an 18-ton class D-Series excavator. It sits between the CX180B and the CX190E in Case’s full-size excavator lineup, representing the Tier 4 Final generation of the 18-ton platform. The D-Series brought a modernized operator station, refined electrohydraulic controls, and the latest emissions aftertreatment to a machine class that has long anchored Case’s general-purpose excavator offering.

Engine, hydraulics, and drivetrain
The CX180D runs a Tier 4 Final diesel through a hydrostatic dual-path drivetrain into a steel-track undercarriage. The main hydraulic pump — a load-sensing piston pump — drives boom, dipper, bucket, swing, and propel circuits through electrohydraulic control valves. Tier 4 Final aftertreatment includes a diesel particulate filter (DPF) and selective catalytic reduction (SCR) catalyst with DEF dosing.
The conventional tail-swing upper frame, steel-track undercarriage, and Case-pattern swing bearing carry forward proven mid-class excavator geometry. The cab is sealed and pressurized with joystick controls, a color monitor for engine and hydraulic status, and integrated aftertreatment monitoring.
Common service items on the CX180D
- Engine internals: Tier 4 Final diesel pistons, rings, sleeves, head gaskets — common-rail injection throughout.
- Tier 4 Final aftertreatment: DPF cleaning service and regen behavior, DEF tank and dosing module, SCR catalyst, EGR cooler service.
- Fuel system: Common-rail injectors, lift pump, primary and secondary fuel 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, 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 inspection and replacement, rollers, idlers, drive sprockets, recoil springs.
- Swing system: Swing motor and reduction gear service, swing bearing inspection, 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.

Need a part for your Case CX180D Excavator?
Aftertreatment components, common-rail fuel system parts, and main hydraulic pumps are the highest-value items on a CX180D. Call our parts team with your serial number and we’ll match the right component to your machine.
Request a PartWhat to verify before ordering
- Serial number. Confirm the serial on the CX180D before ordering year-specific parts.
- Engine serial. Engine internal parts must match the engine serial number.
- 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 during production — 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 CX180D still earns a paycheck
The Case CX180D is an 18-ton class production excavator handling general site work, utility installation, residential and commercial earthmoving, and mining and quarry work depending on configuration. It is the modern, full-emissions Case mid-class excavator that fleets currently in production are running, and parts coverage across the D-Series remains strong.
Maintenance priorities on a CX180D: clean fuel and tight water separation for common-rail injection, DPF regen behavior 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 from the older B-Series machines through the current production D and E Series.
