Case 445CT Compact Track Loader: 2005-2010 400-Series Tier 3 CTL
The Case 445CT 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 445CT sits between the Case 445 and 450CT in the 400-series CTL range.
Where the 445CT fits in the Case skid steer / CTL line
The 445CT sits in the Case 400-series skid steer / CTL range between the Case 445 and the Case 450CT. 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 to the SR/SV/TR/TV designations.
For owners and shops working on a 400-series Case CTL, the 445CT shares much of its hydraulic, electrical, and operator-station architecture with the broader Case/New Holland skid steer / CTL family, which means cross-fit parts coverage is strong - particularly for cylinder seal kits, control valve components, and cab hardware.

Engine, hydraulics, and drivetrain
The 445CT runs a Tier 3 compact diesel through a hydrostatic dual-path drivetrain. Loader hydraulics use a piston pump feeding electrohydraulic control valves. The CTL undercarriage adds track chains, sprockets, idlers, and rollers to the maintenance footprint - track and undercarriage wear is the largest single recurring cost on any 400-series CTL.
The wet-disc park brake is integrated with the hydrostatic deceleration logic, and the loader linkage uses a vertical-lift geometry that gives the 445CT the reach and dump height needed for truck-loading and pallet work. Lift and tilt cylinders run on standard Case/NH seal-kit cross-fit components, so service parts are widely available.
Common service items on the 445CT
- Engine internals: Tier 3 compact diesel - pistons, rings, sleeves, bearings, gaskets. Common-rail high-pressure injection components.
- Fuel system: Common-rail injectors, lift pump, fuel filter and water separator - tight filtration is critical for injector life.
- Cooling system: Radiator, water pump, thermostat, fan, charge-air cooler, hoses, belts.
- Hydraulics: Loader lift and bucket tilt cylinder seal kits (86570919, 86570931, and 86570922 cross-fit on the Case/NH alpha-series), piston-pump rebuilds, electrohydraulic control valves.
- Drivetrain: Hydrostatic dual-path pumps and drive motors, charge pump, hydraulic filters.
- Undercarriage: CTL track chains, sprockets, idlers, rollers - undercarriage wear monitoring is the largest single recurring cost on a 445CT.
- Hardware: 191048A2 axle stud and nut cross-fits broadly across the Case skid steer / CTL line.
- Brakes / control: Park brake, control linkage, 48139268 control shock absorber on Case/NH control valves.
- Electrical / ECU: Engine ECU, machine controller, instrument cluster, sensors, wiring harness.
- Cab / operator station: Cab HVAC, seat, gauges, joystick controls, cab glass, 47405956 windshield wiper blade on cab-equipped units.

Hydraulic cylinder seal kits, hydrostatic drive components, and undercarriage parts are the highest-volume service items on a 445CT. Call our parts team with your serial number.
Request a PartWhat to verify before ordering
- Serial number. The 445CT saw running changes through its 2005-2010 production. Match parts to the machine serial.
- Engine serial. Tier 3 internal engine parts must match the engine serial number.
- Aftertreatment / EGR configuration. Tier 3 configuration varies by build year - confirm EGR cooler and emissions component layout before ordering.
- Hydraulic cylinder bore. Cylinder seal kit fit depends on bore dimension - measure before ordering.
- Cab vs. ROPS canopy. Cab-equipped units have HVAC, wiper, and glass components that canopy-only machines don't carry.
- Undercarriage configuration. Track width and roller count vary - confirm before ordering chains or rollers.
Why the 445CT still earns a paycheck
The Case 445CT 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 400-series shares enough architecture with the modern alpha (SR/SV/TR/TV) family that cross-fit parts coverage remains strong more than a decade after production ended.
Maintenance priorities on a 445CT: 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.
