Case WX160E Wheeled Excavator: E-Series 16-Ton Road-Mobile Excavator

The Case WX160E is a 16-ton E-Series wheeled excavator - the latest-generation Case wheeled-chassis excavator built for road-mobile utility, municipal, and infrastructure work. Tier 4 Final emissions, hydrostatic drive, and a wheeled undercarriage let it drive between job sites under its own power.

Where the WX160E fits in the Case excavator line

The WX160E sits in Case’s WX wheeled excavator range - wheeled-chassis excavators built for road-mobile utility work, municipal applications, and any operation that needs excavator capability without dedicated transport. It positions between the smaller WX155E SR and the larger WX165 in the current E-Series lineup.

Compared to a tracked CX-class excavator of similar tonnage, the WX160E swaps the tracked undercarriage for tires, axles, and final drives, and adds stabilizer outriggers or a dozer-blade stabilizer to plant the chassis during digging cycles. Boom, dipper, bucket, and swing functions are sized to match a comparable-class tracked excavator.

Case WX160E Wheeled Excavator - Quick Specs

Locating your serial number On the Case WX160E the serial number plate is located on the right-hand side of the cab below the front windshield, or inside the cab near the operator’s seat. Confirm the serial before ordering - WX wheeled excavator emissions and ECU calibrations evolved across generations.

Engine, hydraulics, and drivetrain

The WX160E runs a Tier 4 Final diesel through a hydrostatic drivetrain to a wheeled chassis - tires, axles, and final drives in place of a tracked undercarriage. Stabilizer outriggers and/or dozer-blade stabilization keep the chassis planted during digging cycles. Boom, dipper, bucket, and swing functions match a comparable-class tracked CX excavator.

The Tier 4 Final emissions package adds a diesel particulate filter (DPF) and selective catalytic reduction (SCR) with DEF dosing. Common-rail fuel injection delivers the precise timing and pressure the aftertreatment system requires. The hydrostatic drive offers infinitely variable speed control with road-speed and work-speed ranges.

Common service items on the WX160E

Engine internals: Tier 4 Final diesel pistons, rings, sleeves, head gaskets. Common-rail injection.
Tier 4 Final aftertreatment: DPF service intervals 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 / 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.
Wheeled chassis: Tires, wheel bearings, axle and final drive service, suspension if equipped.
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 + wiper: Cab glass and wiper service items - KHN16820 24-inch wiper blade, KHN3046 front lower glass, KHN2632 front upper glass cross-fit across Case and Link-Belt excavators.
Operator station: Seat, joystick controls, pedal linkage, instrument panel, cab HVAC.

Tier 4 Final aftertreatment - service implications The WX160E’s DPF and SCR systems are reliable when fed clean fuel and quality DEF, but they require attention. DEF tank must stay topped up, DPF will request periodic high-temperature regenerations, and NOx sensors fail occasionally and trigger derate conditions if not replaced. Factor aftertreatment service into the maintenance budget on any Tier 4 Final WX machine.

What to verify before ordering

Serial number. Confirm the serial on the WX160E 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 WX160E still earns a paycheck

The Case WX160E is a wheeled excavator for road-mobile utility, municipal, and infrastructure work - it drives between job sites under its own power, eliminating dedicated transport requirements that tracked excavators carry. Common in European municipal fleets and increasingly in North American utility applications.

Maintenance priorities on a WX160E: clean fuel, hydraulic oil condition, tire pressure and wheel-bearing service, axle and final-drive lubrication, outrigger / blade-stabilizer cylinder service, swing-bearing lubrication, and pin / bushing service. Broken Tractor maintains parts coverage across the Case wheeled excavator family.
