Case CX235C SR Excavator: C-Series 23.5-Ton Short-Radius Production Excavator
The Case CX235C SR is a 23.5-ton class C-Series short-radius excavator. Tier 4 Interim emissions, refined cab and electrohydraulic controls, and short-radius tail-swing geometry built for confined-space utility and urban earthmoving.
Where the CX235C SR fits in the Case excavator line
The CX235C SR is a 23.5-ton class C-Series short-radius excavator. It slots between the CX225 SR and the CX240 in Case’s full-size excavator lineup. The SR (short-radius) geometry keeps the counterweight inside the track width, making the CX235C SR ideal for confined-space utility, urban, and curbside work where a conventional tail-swing machine would foul nearby obstacles.

Engine, hydraulics, and drivetrain
The CX235C SR runs a Tier 4 Interim diesel through a hydrostatic dual-path drive 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 short-radius tail-swing geometry reduces the rear counterweight overhang for confined-space work - at the cost of slightly reduced swing stability when lifting at full reach.
Tier 4 Interim aftertreatment uses a DPF (diesel particulate filter) with periodic regeneration, cooled EGR, and on later-build configurations DEF/SCR dosing for NOx control. The C-Series cab is sealed and pressurized with a full instrument cluster, electrohydraulic joystick controls, and improved climate control versus the prior generation.

Need a part for your Case CX235C SR Excavator?
Hydraulic pumps, common-rail fuel components, aftertreatment, and undercarriage are the highest-value items on a CX235C 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
- Serial number. Confirm the serial on the CX235C 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 CX235C SR still earns a paycheck
The Case CX235C SR is a 23.5-ton class production excavator suited to general site work, utility installation, residential and commercial earthmoving, and lighter mining/quarry work depending on configuration. The SR (short-radius) tail-swing geometry adds urban, curbside, and confined-space capability that conventional tail-swing machines can’t match.
Maintenance priorities on a CX235C SR: clean fuel and tight water separation for the common-rail injection system, DPF regen behavior tracking, hydraulic oil condition and filtration, swing-bearing lubrication, steel-track tension and undercarriage wear monitoring, and pin and bushing service at every joint. Broken Tractor maintains parts coverage across the Case excavator family.
