Case CX260E Excavator: E-Series 26-Ton Tier 4 Final Production Excavator
The Case CX260E is a 26-ton class E-Series full-size excavator. It sits between the CX250D and the CX290 in Case's mid-large excavator lineup, running a Tier 4 Final diesel through a hydrostatic dual-path drive into a steel-track undercarriage.
Where the CX260E fits in the Case excavator line
The CX260E is a 26-ton class E-Series excavator. It sits between the CX250D and the CX290 in Case's full-size excavator lineup and represents the current Tier 4 Final emissions generation of the 26-ton platform.
The E-Series carries forward the proven Case CX architecture - load-sensing piston main pump, electrohydraulic control valves, hydrostatic dual-path travel, and a steel-track undercarriage - with refined Tier 4 Final aftertreatment, modernized cab electronics, and updated operator controls.

Engine, hydraulics, and drivetrain
The CX260E runs a Tier 4 Final diesel through a hydrostatic dual-path drivetrain into a steel-track undercarriage. The main hydraulic pump - typically a load-sensing piston pump - drives boom, dipper, bucket, swing, and propel functions through electrohydraulic control valves.
Tier 4 Final aftertreatment uses DPF for particulate control and SCR with DEF dosing for NOx control. The common-rail fuel system requires clean fuel and tight water separation to keep injectors healthy. Swing is driven by a dedicated swing motor and reduction gear riding a serviced swing bearing.
Common service items on the CX260E
- Engine internals: Tier 4 Final diesel pistons, rings, sleeves, head gaskets. Common-rail injection.
- Aftertreatment: DPF service and regeneration behavior, DEF tank and dosing module, SCR catalyst, EGR cooler service.
- 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, and swing cylinder seal kits, main pump rebuild, 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 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 serial on the CX260E 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 CX260E still earns a paycheck
The Case CX260E is a 26-ton class production excavator built for general site work, utility installation, residential and commercial earthmoving, and mining and quarry work depending on configuration. It carries the current Tier 4 Final emissions package on a proven full-size Case CX architecture, with parts coverage backed by the broader CNH/Case dealer network and aftermarket.
Maintenance priorities on a CX260E: clean fuel and tight water separation for common-rail injection, DPF regeneration behavior tracking, hydraulic oil condition, swing-bearing lubrication, steel-track tension and undercarriage wear monitoring, and pin and bushing service across the boom and dipper. Broken Tractor maintains parts coverage across the Case excavator family.
