Case CX470B Hydraulic Excavator: 47-Ton B-Series Production Heavy
The Case CX470B is a 47-ton class B-Series hydraulic excavator built for large production earthmoving, utility, quarry, and mining-edge applications. It sits between the CX460 and the later CX470C in Case's full-size excavator lineup, running a Tier 3 diesel through a hydrostatic dual-path drivetrain and a steel-track undercarriage.

Engine, hydraulics, and drivetrain
The CX470B runs a Tier 3 diesel through a hydrostatic dual-path drivetrain into a steel-track undercarriage. The main hydraulic pump (load-sensing piston pump) drives boom, dipper, bucket, swing, and propel circuits through electrohydraulic control valves. The swing system uses a dedicated swing motor with reduction gear and swing bearing, with a swing brake for hold function.
Common-rail fuel injection demands clean fuel and tight water separation. The cooling package includes a radiator, charge-air cooler on turbo builds, hydraulic oil cooler, and fan drive sized for sustained heavy-load duty cycles typical of a 47-ton machine.
Common service items on the CX470B
- Engine internals: Tier 3 diesel pistons, rings, sleeves, head gaskets, bearings.
- 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 components, 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 + wiper: Cab glass and wiper service items - 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.

Hydraulic main pumps, swing motors, common-rail injectors, and undercarriage components are the highest-value items on a CX470B. Call our parts team with your serial number.
Request a PartWhat to verify before ordering
- Serial number. Confirm the machine serial before ordering year-specific parts - the B-Series saw running changes through production.
- 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.
- Main pump variant. Main hydraulic pump part numbers can vary across the production window.
- 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 chain pitch can vary by configuration.
Why the CX470B still earns a paycheck
The Case CX470B is a 47-ton class production excavator - general site work, utility installation, residential and commercial earthmoving, mining and quarry work depending on configuration. Operators value the B-Series for predictable hydraulic response, a cab and control layout that long-time Case operators are at home in, and a parts footprint that overlaps significantly with the broader CX family and Link-Belt cross-fit components.
Maintenance priorities on a CX470B: clean fuel and tight water separation for common-rail injection, hydraulic oil condition, swing-bearing lubrication, steel-track tension and undercarriage wear monitoring, and pin / bushing service at every boom and dipper joint. Broken Tractor maintains parts coverage across the Case excavator family.
