Case CX460 Hydraulic Excavator: 46-Ton Heavy Production Excavator
The Case CX460 is a 46-ton class hydraulic excavator built for large production, quarry, and mining-edge earthmoving work. It sits between the CX380E and the CX470B in Case’s full-size excavator lineup, running a Tier 2 diesel through a hydrostatic dual-path drive and a steel-track undercarriage.
Where the CX460 fits in the Case excavator line
The CX460 is a 46-ton class production excavator, positioned between the smaller CX380E and the larger CX470B in Case’s full-size excavator lineup. It targets large production earthmoving, utility, quarry, and mining-edge work where a true heavy excavator is needed but the largest 50+ ton machines are oversized.

Engine, hydraulics, and drivetrain
The CX460 runs a Tier 2 diesel through a hydrostatic dual-path drivetrain into a steel-track undercarriage. The main hydraulic system uses a load-sensing piston pump driving boom, dipper, bucket, swing, and propel circuits through electrohydraulic control valves. The hydrostatic dual-path drive gives independent track control for steering, counter-rotation, and gradeability typical of a heavy production excavator.
The implement hydraulic circuit is sized for production digging - boom and dipper cylinders are heavy-section, the main pump and control valve are matched to keep flow up at the bucket under load, and the swing system uses a dedicated motor and reduction gear with a large swing bearing carrying the upper structure.
Common service items on the CX460
- Engine internals: Pistons, rings, sleeves, head gaskets, bearings. Common-rail fuel injection on later builds.
- 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 wipers: Cross-fit Case / Link-Belt service items - KHN16820 24-inch wiper blade, KHN3046 front lower glass, KHN2632 front upper glass.
- Operator station: Seat, joystick controls, pedal linkage, instrument panel, cab HVAC.

Main pumps, swing motors, undercarriage components, and common-rail fuel system parts are the highest-value items on a CX460. Call our parts team with your serial number.
Request a PartWhat to verify before ordering
- Machine serial number. Confirm the serial on the CX460 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.
- Emissions revision. Fuel system and ECU 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.
- Undercarriage configuration. Track shoe width and undercarriage length vary by application.
Why the CX460 still earns a paycheck
The Case CX460 is a 46-ton class production excavator - general site work, utility installation, residential and commercial earthmoving, and mining and quarry work depending on configuration. It hits the size class where a full-frame heavy excavator is needed but a 50+ ton machine would be overkill, and it does so with a hydraulic system sized for serious production digging.
Maintenance priorities on a CX460: clean fuel and tight water separation for common-rail injection, hydraulic oil condition, swing-bearing lubrication, steel-track tension and undercarriage wear monitoring, and pin and bushing service at the boom and dipper joints. Broken Tractor maintains parts coverage across the Case CX excavator family from the smaller CX series up through the CX470B and beyond.
