Case 440CT Compact Track Loader: 2005–2010 Tier 3 400-Series CTL
The Case 440CT is part of Case’s 400-series skid steer / compact track loader family - Tier 3 compact diesel, hydrostatic dual-path drive, and the operator interface that bridged the XT-series and the modern alpha (SR/SV/TR/TV) lineup. Produced from 2005 through 2010, the 440CT sits in the middle of the 400-series CTL range.
Where the 440CT fits in the Case skid steer / CTL line
The 440CT sits in the Case 400-series skid steer / CTL range between the Case 440 and the Case 445. Tier 3 compact diesel architecture, electronic engine controls, and the cab and instrumentation defined Case’s mid-2000s skid steer / CTL line before the alpha rename to the SR/SV/TR/TV family.
As the “CT” variant, the 440CT runs the compact track loader undercarriage rather than the wheeled skid steer setup of the 440. Track chains, sprockets, idlers, and rollers add capability on soft ground and snow at the cost of higher recurring undercarriage wear.

Engine, hydraulics, and drivetrain
The 440CT runs a Tier 3 compact diesel through a hydrostatic dual-path drivetrain. Loader hydraulics use a piston pump with electrohydraulic control valves. The CTL undercarriage adds track chains, sprockets, idlers, and rollers - track wear is the largest single recurring cost on a 400-series CTL. A wet-disc park brake is integrated with the hydrostatic deceleration logic.
Operator controls were available in both mechanical-pilot and electrohydraulic (EH) configurations depending on build year and option package. Cab-equipped units add HVAC, cab glass, and the full instrument cluster; ROPS canopy units delete the enclosure but keep the same control architecture.
Common service items on the 440CT
- Engine internals: Tier 3 compact diesel pistons, rings, sleeves, bearings, gaskets. Common-rail high-pressure injection.
- Fuel system: Common-rail injectors, lift pump, very tight water-separator filtration.
- Cooling system: Radiator, water pump, thermostat, fan, charge-air cooler, hoses, belts. EGR cooler service on Tier 3 builds.
- Hydraulics: Loader lift and bucket tilt cylinder seal kits (86570919 / 86570931 / 86570922 cross-fit on NH/Case alpha-series), piston-pump rebuilds, electrohydraulic control valves.
- Drivetrain: Hydrostatic dual-path pumps and drive motors, charge pump, filters. CTL undercarriage adds track chains, sprockets, idlers, rollers - undercarriage wear monitoring is the largest single recurring cost on a CTL.
- Hardware: 191048A2 axle stud & nut cross-fits broadly across the Case skid steer line.
- Brakes / control: Park brake, control linkage, 48139268 control shock absorber on Case/NH alpha-series control valves.
- Electrical / ECU: Engine ECU, machine controller, instrument cluster, sensors, wiring harness, telematics module.
- Cab / operator station: Cab HVAC, seat, gauges, joystick controls, cab glass, 47405956 windshield wiper blade on cab-equipped units.

Request a PartWhat to verify before ordering
- Aftertreatment generation. Tier 3 configuration varies by build year - confirm the layout before ordering.
- Serial number. Confirm the serial on the Case 440CT before ordering year-specific parts.
- Engine serial. Internal engine parts must match the engine serial number.
- Hydraulic cylinder bore. Cylinder seal kit fit depends on bore dimension - measure before ordering.
- Cab vs. ROPS canopy. Operator station equipment varied between configurations.
- Control type. Mechanical-pilot vs. electrohydraulic (EH) joystick controls affect control valve and harness part numbers.
Why the 440CT still earns a paycheck
The Case 440CT is the mid-2000s Case compact track loader that bridged the XT-series and the current alpha lineup. Tier 3 emissions, modern electronics, and the cab ergonomics put the operator in a better seat than the XT predecessor while keeping the mechanical layout familiar to anyone who’s wrenched on a 400-series.
Maintenance priorities on a 440CT: clean fuel and tight water separation for common-rail injection, hydrostatic charge pressure monitoring, and track tension and undercarriage wear monitoring. Broken Tractor maintains parts coverage across the 400-series and the broader Case skid steer / CTL family.
