Case CX490D Excavator: D-Series 49-Ton Tier 4 Final Production Excavator
The Case CX490D is a 49-ton class D-Series excavator running a Tier 4 Final diesel through a hydrostatic dual-path drivetrain into a steel-track undercarriage. It sits between the CX470C and the CX750D in Case’s full-size excavator lineup and is the production-grade 49-ton choice for general site work, utility installation, and quarry duty.
Where the CX490D fits in the Case excavator line
The CX490D is a 49-ton class D-Series excavator, sitting between the smaller CX470C and the larger CX750D in Case’s full-size excavator family. The D-Series brought Tier 4 Final emissions compliance to the heavy class, with refined electrohydraulic controls, updated cab electronics, and an aftertreatment package built around DPF and SCR.

Engine, hydraulics, and drivetrain
The CX490D 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 circuits through electrohydraulic control valves. Common-rail fuel injection and the DPF/SCR aftertreatment package require clean fuel and quality DEF to stay in service.
The undercarriage uses heavy-duty steel tracks with conventional rollers, idlers, sprockets, and recoil springs sized for the 49-ton class. The swing system pairs a high-torque swing motor and reduction gear over a sealed swing bearing.
Common service items on the CX490D
- Engine internals: Tier 4 Final diesel pistons, rings, sleeves, head gaskets, bearings. Common-rail injection components.
- Tier 4 Final aftertreatment: DPF service and regeneration components, DEF tank and dosing module, SCR catalyst, 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 and belts.
- Hydraulic system: Boom, dipper, bucket, and swing cylinder seal kits, main pump rebuild parts, 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, harnesses, 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.

Need a part for your Case CX490D Excavator?
Hydraulic, aftertreatment, and undercarriage components are the highest-value items on a 49-ton CX490D. Call our parts team with your serial number and we will match the right component to your machine.
Request a PartWhat to verify before ordering
- Serial number. Confirm the machine serial on the CX490D 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 CX490D still earns a paycheck
The Case CX490D is a 49-ton class production excavator - general site work, utility installation, residential and commercial earthmoving, and mining and quarry work depending on configuration. It is a full Tier 4 Final machine with modern electrohydraulic controls and a cab that meets the operator-experience expectations of any current heavy excavator.
Maintenance priorities on a CX490D: 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.
