Case CX190E Hydraulic Excavator: Tier 4 Final 19-Ton E-Series
The Case CX190E is the 19-ton class E-Series hydraulic excavator, sitting between the CX180D and the 21-ton CX210 line. E-Series brought Tier 4 Final emissions, refined electrohydraulic controls, and an upgraded operator station to Case's mid-class production excavator.
Where the CX190E fits in the Case excavator line
The CX190E is a 19-ton class E-Series excavator, positioned between the CX180D and the 21-ton CX210 in Case's full-size excavator lineup. E-Series machines run Tier 4 Final aftertreatment, refined electrohydraulic control valves, and an updated operator station with a full-color monitor display.

Engine, hydraulics, and drivetrain
The CX190E 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 boom, dipper, bucket, swing, and propel functions through electrohydraulic control valves.
Tier 4 Final aftertreatment includes a diesel particulate filter (DPF), selective catalytic reduction (SCR) with DEF dosing, and cooled exhaust gas recirculation (EGR). These systems require clean fuel, quality DEF, and periodic DPF regeneration to stay healthy.
Common service items on the CX190E
- Engine internals: Tier 4 Final diesel pistons, rings, sleeves, head gaskets, bearings. Common-rail injection.
- Aftertreatment: DPF service and replacement, DEF tank and dosing module, SCR catalyst, EGR cooler.
- Fuel system: Common-rail injectors, lift pump, high-pressure pump, primary and secondary filters with tight water separation.
- 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 hardware, quick coupler service.
- Undercarriage: Steel track chains, rollers, idlers, drive sprockets, recoil springs.
- Swing system: Swing motor, reduction gear, 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 CX190E 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 CX190E still earns a paycheck
The Case CX190E is a 19-ton class production excavator handling general site work, utility installation, residential and commercial earthmoving, and quarry work depending on configuration. The E-Series refinements - electrohydraulic control valves, full-color monitor, and refined Tier 4 Final powertrain - make it a comfortable, productive mid-class machine that fits between the CX180D and the CX210.
Maintenance priorities on a CX190E: clean fuel and 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. Broken Tractor maintains parts coverage across the Case excavator family.
