Case TV450B Compact Track Loader: Alpha-Series Vertical-Lift CTL
The Case TV450B is part of Case's alpha-series TV (vertical-lift) compact track loader range — Tier 4 Final compact diesel, hydrostatic dual-path drive on a tracked undercarriage, and vertical-lift loader geometry that maximizes forward reach at full height. Best matched to truck-loading and stacking work where reach matters and ground pressure matters even more.
Where the TV450B fits in the Case skid steer / CTL line
The TV450B sits in Case's alpha-series TV (vertical-lift) compact track loader range between the Case TV450 and the Case TV620B. Tracked undercarriage, vertical-lift loader geometry, and Tier 4 Final aftertreatment make it the modern higher-capacity CTL in the alpha-series lineup.

Engine, hydraulics, and drivetrain
The TV450B runs a Tier 4 Final compact diesel through a hydrostatic dual-path drivetrain on a tracked undercarriage. Loader hydraulics use a load-sensing piston pump with electrohydraulic control valves. Vertical-lift geometry keeps the bucket forward through the lift arc — best matched to truck-loading and stacking.
CTL undercarriage life is the largest single recurring cost on this platform. Sprocket, roller, idler, and chain monitoring matter as much as engine and hydraulic maintenance. Track tension and ground-engagement habits drive wear rates more than hours alone.
Common service items on the TV450B
- Engine internals: Tier 4 Final compact diesel: pistons, rings, sleeves, bearings, gaskets. Common-rail high-pressure injection.
- Tier 4 aftertreatment: DPF service intervals, DEF tank and dosing module, SCR catalyst, EGR cooler service.
- Fuel system: Common-rail injectors, lift pump, very 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, and rollers.
- Bucket coupler hardware: 47396814K bucket pin kit cross-fits L216–L230, C232–C238, SR160–SR250, SV185–SV300, TV380, and TR270–TR340.
- 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 TV450B Compact Track Loader?
Aftertreatment, hydrostatic drive components, and CTL undercarriage are the highest-value items on a TV450B. Call our parts team with your serial number and we'll match the right component to your machine.
Request a PartWhat to verify before ordering
- Serial number. Confirm the serial on the Case TV450B before ordering year-specific parts.
- Engine serial. Internal engine parts must match the engine serial number.
- Aftertreatment + undercarriage generation. Tier 4 Final aftertreatment configuration varies by build year; CTL undercarriage components saw revisions — confirm by serial.
- Hydraulic cylinder bore. Cylinder seal kit fit depends on bore dimension — measure before ordering.
- Cab vs. ROPS canopy. Operator station equipment varied between configurations.
- High-flow vs. standard auxiliary hydraulics. Confirm the aux-hydraulic configuration before ordering valve or coupler parts.
Why the TV450B still earns a paycheck
The Case TV450B is the alpha-series CTL that pairs vertical-lift loader geometry with a tracked undercarriage — flotation for soft material plus forward reach at full height. Truck-loading, stacking, and high-capacity material handling on soft ground are where this configuration shines over a radial-lift skid steer.
Maintenance priorities on a TV450B: clean fuel and tight water separation (Tier 4 Final common-rail injectors don't tolerate contamination), DPF regen behavior, hydrostatic charge pressure, and undercarriage wear monitoring (track tension, sprocket and roller wear, idler condition). Stay on top of those and the platform will return solid uptime for years.
