Case 445 Skid Steer Loader: 2004–2010 Tier 3 400-Series Skid Steer
The Case 445 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 2004 into 2010, the 445 set the mid-frame Case skid steer template that customers still run today.
Where the 445 fits in the Case skid steer line
The 445 sits in the Case 400-series skid steer / CTL range between the Case 440 and the Case 465. 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 series.
The 445 was offered with a fully sealed and pressurized cab option, ROPS canopy configuration, and was available with mechanical or pilot-control hand and foot operation. It shared a substantial parts catalog with its New Holland-badged siblings under the CNH umbrella, which is why so many cross-reference numbers in the field point back to L-series and alpha-series New Holland skid steers.

Engine, hydraulics, and drivetrain
The 445 runs a Tier 3 compact diesel through a hydrostatic dual-path drivetrain. Loader hydraulics use a piston pump with electrohydraulic control valves on equipped configurations. A wet-disc park brake is integrated with the hydrostatic deceleration logic, and the auxiliary hydraulic circuit supports the standard universal skid-steer attachment interface.
Fuel delivery on the 445 is a tightly filtered common-rail-style system. Clean fuel and aggressive water separation are non-negotiable on this generation of CNH compact diesel — injector replacements are the most common high-dollar engine repair on neglected machines.
Common service items on the 445
- Engine internals: Tier 3 compact diesel pistons, rings, sleeves, bearings, gaskets.
- Fuel system: Common-rail injectors, lift pump, fuel filters, water-separator service.
- 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.
- 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.

Need a part for your Case 445 Skid Steer Loader?
Hydraulic seal kits, common-rail injectors, and hydrostatic drive components are the highest-value items on a 445. Call our parts team with your serial number.
Request a PartWhat to verify before ordering
- Serial number. Confirm the serial on the Case 445 before ordering year-specific parts — the 400-series saw multiple running changes.
- 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 — glass, HVAC, and harness part numbers differ.
- Control configuration. Mechanical hand/foot vs. pilot-control joystick machines use different valve and linkage components.
Why the 445 still earns a paycheck
The Case 445 is the mid-2000s Case skid steer loader that bridged the XT-series and the current alpha lineup. Tier 3 emissions, modern electronics, and the cab ergonomics that put the operator in a better seat than the XT predecessor. Parts coverage is strong because the CNH parts catalog is shared with the New Holland L-series and alpha-series skid steers — many components cross-fit between badges.
Maintenance priorities on a 445: clean fuel and tight water separation for common-rail injection, hydrostatic charge pressure, drive-chain tension, and cylinder seal condition. Broken Tractor maintains parts coverage across the 400-series and the broader Case skid steer / CTL family.
