Engine, hydraulics, and drivetrain
The CX170E runs a Tier 4 Final diesel through a hydrostatic dual-path drivetrain into a steel-track undercarriage. A load-sensing piston main hydraulic pump drives boom, dipper, bucket, swing, and propel circuits through electrohydraulic control valves. The combination delivers smooth, repeatable cycle times and reduced fuel consumption versus the prior generation.
Tier 4 Final aftertreatment includes a diesel particulate filter (DPF) for soot control and an SCR catalyst with DEF dosing for NOx reduction. EGR is integrated upstream. These systems are reliable when fed clean fuel and quality DEF but add maintenance points compared with earlier emissions tiers.
Common service items on the CX170E
- Engine internals: Tier 4 Final diesel pistons, rings, sleeves, head gaskets. Common-rail injection.
- Aftertreatment: DPF service and regeneration, 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, 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 CX170E 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 CX170E still earns a paycheck
The Case CX170E is a 17-ton class production excavator built for general site work, utility installation, residential and commercial earthmoving, and mining and quarry work depending on configuration. As the current E-Series machine in the mid-size class, it brings the latest emissions, controls, and operator-experience refinements to the Case excavator family.
Maintenance priorities on a CX170E: clean fuel and tight water separation for common-rail injection, DPF regen behavior tracking, quality DEF for SCR protection, 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.
