Case CX245D SR Excavator: D-Series 24.5-Ton Short-Radius Excavator
The Case CX245D SR is a 24.5-ton class D-Series short-radius excavator built for confined-space and urban earthmoving in the 24-ton class. Tier 4 Final emissions, hydrostatic dual-path drive, and short-radius tail-swing geometry put it between the CX240D and CX250C in Case's full-size excavator lineup.
Where the CX245D SR fits in the Case excavator line
The CX245D SR is a 24.5-ton class D-Series short-radius excavator. It sits between the CX240D and the CX250C in Case’s full-size excavator lineup. SR (short-radius) geometry keeps the counterweight inside or very close to the track width, which makes the CX245D SR ideal for confined-space utility work, curbside jobs, and urban builds where rear swing clearance is a constraint.

Engine, hydraulics, and drivetrain
The CX245D SR runs a Tier 4 Final 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. 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.
Tier 4 Final aftertreatment - DPF, SCR catalyst with DEF dosing, and EGR cooler - is fully integrated into the engine package. These systems are reliable when fed clean fuel and quality DEF, but they require active management: DPF regen behavior monitoring, DEF top-ups, and replacement of NOx and pressure sensors as they fail.
Common service items on the CX245D SR
- Engine internals: Tier 4 Final diesel pistons, rings, sleeves, head gaskets, common-rail injection components.
- Aftertreatment: DPF service and replacement, DEF tank and dosing module, SCR catalyst, NOx sensors, EGR cooler.
- 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: Main pump rebuild, boom / dipper / bucket / swing cylinder seal kits, electrohydraulic control valves, hoses.
- Boom and dipper: Pin and bushing service at every joint, bucket pins, thumb 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, harnesses, telematics module on equipped units.
- Cab glass and wipers: 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.

Need a part for your Case CX245D SR Excavator?
Tier 4 Final aftertreatment, common-rail fuel components, and hydraulic pumps are the highest-value items on a CX245D SR. Call our parts team with your serial number and we’ll match the right component to your machine.
Request a PartWhat to verify before ordering
- Machine serial number. Confirm the serial on the CX245D SR 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 CX245D SR still earns a paycheck
The Case CX245D SR is a 24.5-ton class production excavator handling general site work, utility installation, residential and commercial earthmoving, and mining or quarry work depending on configuration. The SR tail-swing geometry adds urban, curbside, and confined-space capability that conventional-radius 24-ton excavators can’t offer.
Maintenance priorities on a CX245D SR are clean fuel with 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 every boom and dipper joint. Broken Tractor maintains parts coverage across the Case D-Series excavator family.
