Case CX225 SR Excavator: 22.5-Ton Short-Radius Production Excavator
The Case CX225 SR is a 22.5-ton class short-radius excavator built for confined-space utility and urban earthmoving where rear counterweight overhang is a problem. Tier 3 diesel power, hydrostatic dual-path drive, and steel-track undercarriage on a tail-swing geometry that keeps the counterweight inside track width.
Where the CX225 SR fits in the Case excavator line
The CX225 SR is a 22.5-ton class short-radius excavator in Case’s full-size excavator lineup. It sits between the CX220E and the CX235C SR, with SR (short-radius) tail-swing geometry that keeps the counterweight inside the track width - ideal for confined-space utility work, urban jobsites, and curbside work where a conventional tail-swing machine would foul traffic or structures.

Engine, hydraulics, and drivetrain
The CX225 SR runs a Tier 3 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 functions through electrohydraulic control valves.
Short-radius tail-swing geometry reduces the rear counterweight overhang for confined-space work, at the cost of slightly lower swing stability when lifting at full reach. Plan rigging picks accordingly - load charts for SR machines are tighter at the rear quadrant than equivalent conventional tail-swing excavators.
Common service items on the CX225 SR
- Engine internals: Pistons, rings, sleeves, head gaskets, bearings - common-rail Tier 3 diesel.
- 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.
- H-link / boom geometry: H-link bushing service - 160447A1 H-link bushing fits CX210, CX225 SR, 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, 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 before ordering year-specific parts. The CX225 SR had running changes through its 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.
- Emissions revision. Aftertreatment 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 CX225 SR still earns a paycheck
The Case CX225 SR is a 22.5-ton class production excavator - general site work, utility installation, residential and commercial earthmoving, and mining or quarry work depending on configuration. The short-radius tail-swing adds urban, curbside, and confined-space capability that a conventional tail-swing machine can’t match.
Maintenance priorities on a CX225 SR: 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 and bushing service at every boom joint. Broken Tractor maintains parts coverage across the Case excavator family.
