Case 450CT Compact Track Loader: 400-Series Tier 3 CTL
Produced from 2006 to 2010, the Case 450CT 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.
Where the 450CT fits in the Case skid steer / CTL line
The 450CT sits in the Case 400-series skid steer / CTL range between the Case 445CT and the Case 450. Tier 3 compact diesel architecture, electronic engine controls, and the cab and instrumentation that defined Case's mid-2000s skid steer / CTL line before the alpha rename.

Engine, hydraulics, and drivetrain
The 450CT runs a Tier 3 compact diesel through a hydrostatic dual-path drivetrain. Loader hydraulics use a piston pump with electrohydraulic control valves. CTL undercarriage adds track chains, sprockets, idlers, and rollers - track wear is the largest single recurring cost on a 400-series CTL. The wet-disc park brake is integrated with the hydrostatic deceleration logic.
The cab and operator station carry forward Case's mid-2000s skid steer / CTL ergonomics: gauge cluster, joystick controls on equipped configurations, and HVAC on cab-equipped units. The 450CT's track undercarriage gives it the flotation and ground-pressure advantage over the wheeled 450 skid steer variant for soft-ground, landscaping, and finish-grade work.
Common service items on the 450CT
- Engine internals: Tier 3 compact diesel pistons, rings, sleeves, bearings, gaskets. Common-rail high-pressure injection on later builds.
- Aftertreatment / emissions: EGR cooler service on Tier 3 builds.
- Fuel system: Common-rail injectors, lift pump, tight water-separator filtration.
- Cooling system: Radiator, water pump, thermostat, fan, charge-air cooler, hoses, belts.
- 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.

Need a part for your Case 450CT Compact Track Loader?
Hydrostatic drive components, undercarriage wear parts, and Tier 3 engine internals are the highest-value items on a 450CT. Call our parts team with your serial number.
Request a PartWhat to verify before ordering
- Serial number. Confirm the machine serial on the 450CT before ordering year-specific parts - the 400-series saw multiple running changes.
- Engine serial. Internal engine parts must match the engine serial number.
- Emissions configuration. Tier 3 configuration varies by build year - confirm EGR and aftertreatment layout before ordering.
- Hydraulic cylinder bore. Cylinder seal kit fit depends on bore dimension - measure before ordering.
- Cab vs. ROPS canopy. Operator station equipment varied between cab and canopy configurations.
- Undercarriage configuration. Track width and tread pattern affect chain, sprocket, and roller part numbers.
Why the 450CT still earns a paycheck
The Case 450CT is the mid-2000s Case compact track loader that bridged the XT-series and the current alpha lineup. Tier 3 emissions, modern electronics, and cab ergonomics that put the operator in a better seat than the XT predecessor. The CTL undercarriage gives it the flotation advantage over wheeled skid steers for soft-ground, landscape, and finish-grade applications.
Maintenance priorities on a 450CT: clean fuel and tight water separation for common-rail injection, hydrostatic charge pressure, and track tension and undercarriage wear monitoring. Broken Tractor maintains parts coverage across the 400-series and the broader Case skid steer / CTL family.
