Case CX80C Midi Excavator: 2014-Present 8-Ton Tier 4 Final C-Series
The Case CX80C is the 8.0-ton conventional tail-swing entry in Case's C-Series midi excavator range, slotting between the mini line and the full-size CX130. Tier 4 Final diesel, hydrostatic dual-path drive, and a steel-track undercarriage make it a working tool for utility, residential bulk earthwork, and mid-size site preparation.
Where the CX80C fits in the Case excavator line
The CX80C sits in Case's midi excavator range (7-10 ton class), between the mini line and the full-size CX130 and larger machines. Its conventional tail-swing geometry maximizes counterweight effectiveness and gives the operator full mid-size digging stability and bucket reach, while still keeping the road footprint small enough for utility, residential, and urban site work.

Engine, hydraulics, and drivetrain
The CX80C runs a Tier 4 Final diesel through a hydrostatic dual-path drivetrain into a steel-track undercarriage. Main hydraulic pump drives boom, dipper, bucket, swing, and propel functions through electrohydraulic control valves. Conventional tail-swing geometry maximizes counterweight effectiveness for digging stability, and steel tracks support the heavier midi-class weights and abrasive-material work that mini machines aren't built for.
Tier 4 Final aftertreatment - DPF, DEF dosing, SCR catalyst, and EGR - adds service requirements that didn't exist on earlier emissions tiers. Clean fuel, quality DEF, and routine DPF service are not optional on a machine in this class.
Common service items on the CX80C
- Engine internals: Tier 4 Final diesel pistons, rings, sleeves, head gaskets, common-rail injection components.
- Tier 4 Final aftertreatment: DPF service intervals and regeneration behavior, DEF tank and dosing module, SCR catalyst, EGR cooler.
- Fuel system: Common-rail injectors, 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, 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, harnesses, 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
- Serial number. Confirm the serial on the CX80C before ordering year-specific parts.
- Engine serial. Engine internal parts must match the engine serial number.
- Hydraulic cylinder bore. 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 CX80C still earns a paycheck
The Case CX80C is the midi-class excavator for jobs that demand more reach, depth, and bucket capacity than a mini can deliver but don't need the road footprint of a full-size 13+ ton machine. Utility contractors, urban construction crews, mid-size site work, and residential bulk excavation are the natural home for the 8-ton class.
Maintenance priorities on a CX80C: clean fuel and tight water separation for common-rail injection, DPF regen behavior tracking, hydraulic system condition, steel-track tension and wear monitoring, swing-bearing lubrication, and pin and bushing service across the boom and dipper. Broken Tractor maintains parts coverage across the Case excavator family.
