Case CX210 Excavator: The Original 21-Ton CX-Series Excavator
The Case CX210 is the foundational 21-ton class machine in Case’s CX excavator lineup. Positioned between the smaller CX190E and the later CX210B, it pairs a Tier 2 diesel with a hydrostatic dual-path drive and a conventional-tail-swing, steel-track undercarriage built for general site work, utility, and earthmoving.
Where the CX210 fits in the Case excavator line
The CX210 is a 21-ton class Original-generation excavator, sitting between the CX190E below it and the CX210B above it in Case’s full-size excavator lineup. It set the platform that later CX-series 21-ton machines built on, with conventional tail swing, a steel-track undercarriage, and a load-sensing hydraulic main pump driving boom, dipper, bucket, swing, and propel circuits.

Engine, hydraulics, and drivetrain
The CX210 runs a Tier 2 diesel through a hydrostatic dual-path drivetrain into a steel-track undercarriage. The main hydraulic pump - commonly a load-sensing piston pump - drives boom, dipper, bucket, swing, and propel through electrohydraulic control valves. Implement response and propel modulation are tuned for the 21-ton class, with conventional-tail-swing geometry that prioritizes lifting capacity over tight-quarters reach.
The H-link boom geometry uses the well-known 160447A1 H-link bushing, which is a direct fit on the CX210 and also cross-fits the CX225SR and 9030B - useful for shops servicing multiple 21-ton Case excavators.
Common service items on the CX210
- Engine internals: Pistons, rings, sleeves, head gaskets, bearings on the Tier 2 base engine.
- Fuel system: Injectors, lift pump, primary and secondary filters with tight water-separator standards.
- Cooling system: Radiator, water pump, thermostat, fan, charge-air cooler on turbo builds, hoses and belts.
- Hydraulic system: Boom, dipper, bucket, and swing cylinder seal kits; main pump rebuild components; electrohydraulic control valves; high-pressure and return hoses.
- H-link and boom geometry: H-link bushing service - the 160447A1 H-link bushing is a direct fit on CX210, CX225SR, and 9030B.
- 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.
- 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 CX210 serial 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.
- Hydraulic main pump variant. Pump part numbers can vary across production - confirm against the pump tag.
- Engine ECU calibration. 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 CX210 still earns a paycheck
The Case CX210 is a 21-ton class production excavator that still shows up daily on general site work, utility installation, residential and commercial earthmoving, and mining or quarry work depending on configuration. The Original CX platform was engineered for high cycle counts and predictable serviceability, and the aftermarket has matured around its key wear items - bushings, seal kits, undercarriage components, and cab glass.
Maintenance priorities on a CX210 are: clean fuel and tight water separation for the injection system, hydraulic oil condition and filtration, swing-bearing lubrication, steel-track tension and undercarriage wear monitoring, and pin and bushing service at the H-link and the major boom and dipper joints. Broken Tractor maintains parts coverage across the Case excavator family.
