Case CX470C Hydraulic Excavator: C-Series 47-Ton Production Excavator
The Case CX470C is a 47-ton class C-Series hydraulic excavator built for heavy production earthmoving, utility, mining, and quarry work. It runs a Tier 4 Interim diesel through a load-sensing hydraulic system and sits between the CX470B and the later CX490D in Case's full-size excavator lineup.
Where the CX470C fits in the Case excavator line
The CX470C is a 47-ton class C-Series excavator. It sits between the earlier CX470B and the later CX490D in Case's full-size excavator lineup, carrying the C-Series refinements: Tier 4 Interim emissions, an updated load-sensing hydraulic system, and a refined operator station. The serial plate is located on the right-hand side of the lower cab frame, just below the windshield - confirm yours before ordering production-window-specific parts.

Engine, hydraulics, and drivetrain
The CX470C runs a Tier 4 Interim diesel through a hydrostatic dual-path drivetrain into a steel-track undercarriage. The main hydraulic pump is a load-sensing piston pump driving boom, dipper, bucket, swing, and propel circuits through electrohydraulic control valves. The common-rail fuel system delivers tight injection tolerances - clean fuel and disciplined water separation are non-negotiable on this generation.
Aftertreatment on the Tier 4 Interim build includes diesel particulate filter (DPF) regeneration, an EGR cooler, and on later builds DEF/SCR dosing. The swing system uses a dedicated swing motor and reduction gear riding on a swing bearing - lubrication discipline at this joint is one of the highest-payoff maintenance items on the machine.
Common service items on the CX470C
- Engine internals: Tier 4 Interim diesel - pistons, rings, sleeves, head gaskets, common-rail injection components.
- 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: 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 machine serial on the CX470C 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.
- Undercarriage configuration. Track shoe width and link pitch vary - measure before ordering chains and shoes.
Why the CX470C still earns a paycheck
The Case CX470C is a 47-ton class production excavator built for general site work, utility installation, residential and commercial earthmoving, mining, and quarry work depending on configuration. The C-Series platform brought refined hydraulic controls and a modern operator station to the 47-ton class, and machines from this generation continue to log production hours across North America.
Maintenance priorities on a CX470C: clean fuel and tight water separation for common-rail injection, DPF regen behavior tracking, hydraulic oil condition monitoring, swing-bearing lubrication, steel-track tension and undercarriage wear monitoring, and pin and bushing service at every boom joint. Broken Tractor maintains parts coverage across the Case excavator family.
