Case CX210C Excavator: 2012–2017 21-Ton C-Series Excavator
The Case CX210C is a 21-ton class C-Series excavator produced from 2012 to 2017. It brought Tier 4 Interim emissions, a refined operator cab, and updated hydraulics to the 21-ton platform, sitting between the CX210B and CX210D in Case’s full-size excavator line.
Where the CX210C fits in the Case excavator line
The CX210C is a 21-ton class C-Series excavator. It sits between the CX210B and the CX210D in Case’s full-size excavator lineup, and represents the Tier 4 Interim generation of the 21-ton platform. The C-Series brought refined cab ergonomics, updated electrohydraulic controls, and the emissions hardware that the platform would carry forward into the later D-Series.

Engine, hydraulics, and drivetrain
The CX210C runs a Tier 4 Interim diesel through a hydrostatic dual-path drivetrain into a steel-track undercarriage. The main hydraulic pump - commonly a load-sensing piston pump - drives the boom, dipper, bucket, swing, and propel circuits through electrohydraulic control valves. Tier 4 Interim emissions hardware includes a DPF, EGR cooler, and on later builds DEF/SCR aftertreatment.
The boom and dipper run on the conventional 21-ton geometry with pinned and bushed joints at every pivot. Standard configurations include a counterweight sized for the 21-ton class and a steel-track undercarriage with sealed-and-lubricated chain.
Common service items on the CX210C
- Engine internals: Tier 4 Interim diesel rebuild kits - pistons, rings, sleeves, head gaskets. Common-rail injection.
- Aftertreatment: DPF service intervals and regeneration behavior; DEF tank and dosing module, SCR catalyst; EGR cooler service.
- 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 / 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: Cab glass and wiper service items - KHN16820 24-inch wiper blade, KHN3046 front lower glass, 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 CX210C Excavator?
Hydraulic components, common-rail fuel system parts, and undercarriage are the highest-value items on a CX210C. Call our parts team with your serial number.
Request a PartWhat to verify before ordering
- Serial number. Confirm the serial on the CX210C 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 CX210C still earns a paycheck
The Case CX210C is a 21-ton class production excavator - general site work, utility installation, residential and commercial earthmoving, mining and quarry work depending on configuration. The 21-ton class is one of the most-used excavator sizes in North American construction, and the CX210C remains a common sight on production fleets.
Maintenance priorities on a CX210C: clean fuel and tight water separation for common-rail injection, DPF regen behavior tracking, hydraulic oil condition, swing-bearing lubrication, steel-track tension and undercarriage wear monitoring, and pin and bushing service at the boom and dipper joints. Broken Tractor maintains parts coverage across the Case excavator family.
