Case 70XT Skid Steer Loader: XT-Series Cummins-Powered Skid Steer
The Case 70XT is part of the XT-series skid steer loader line - Cummins-powered, hydrostatic dual-path drivetrain, and a modernized cab and electrical layout versus the vintage 18-series. The XT-series bridges the older 18-series simplicity and the later alpha-series machines, with strong breakout force and high lift capacity for its class.
Where the 70XT fits in the Case skid steer line
The 70XT sits in the XT-series Case skid steer range between the Case 60XT and the Case 75XT. It runs a Cummins industrial diesel through a hydrostatic dual-path drivetrain, and uses the XT-series cab with improved ergonomics over the 18-series predecessors. The XT-series sits between the vintage 18-series machines and the later alpha-series skid steers with their fully modern electronics.

Engine, hydraulics, and drivetrain
The 70XT runs a Cummins 4B family four-cylinder industrial diesel through a hydrostatic dual-path drivetrain - closed-loop pumps drive sprocket-shaft motors that turn the drive chains. Loader hydraulics use a piston pump with electrohydraulic-pilot or mechanical control valves and direct-acting lift and tilt cylinders. The Cummins 4B is one of the most-produced industrial diesels ever built, which keeps parts coverage strong for the 70XT decades after production.
Breakout force and lift capacity are at the high end of the XT-series. The hydrostatic dual-path setup is service-friendly - drive pumps and motors are individually rebuildable, and the drive chains run in oil-bath chaincase housings.
Common service items on the 70XT
- Engine internals: Cummins 4B or 4BT pistons, rings, sleeves, bearings, gaskets. Mechanical-injection (early) to electronic (late) variants - confirm by serial.
- Fuel system: Cummins fuel injection, injectors, lift pump, filters.
- Cooling system: Radiator, water pump, thermostat, fan, charge-air cooler (turbo variants), hoses, belts.
- Hydraulics: Loader lift and bucket tilt cylinder seal kits, piston-pump rebuilds, control valves, hoses. DMEL1075 cylinder spanner wrench for cylinder service.
- Drivetrain: Hydrostatic dual-path pumps and drive motors, drive chains, sprockets, axles. D64175 sprocket shaft needle bearing cross-fits broadly.
- Hardware: 191048A2 axle stud and nut cross-fits Case skid steer axle studs.
- Brakes and control: Park brake, control linkage, 48139268 control shock absorber for Case/NH skid steer control valves.
- Electrical: Starter, alternator, wiring harness, gauges, switches, 47405956 windshield wiper blade on cab-equipped XT units.
- Cab and operator station: Seat, cab glass, ROPS canopy, gauges, joystick controls.

Need a part for your Case 70XT Skid Steer Loader?
Cummins engine parts, hydrostatic drive components, and cylinder seal kits are the highest-value items on a 70XT. Call our parts team with your serial number.
Request a PartWhat to verify before ordering
- Serial number. Confirm the serial on the Case 70XT before ordering year-specific parts - XT-series production saw running changes.
- Engine serial. Cummins 4B internal parts must match the engine serial number. Mechanical vs. electronic injection variants share many parts but not all.
- 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, wiper, and HVAC parts are cab-only.
- Control configuration. Mechanical foot/hand controls vs. electrohydraulic pilot joystick configurations affect control valves and harnesses.
Why the 70XT still earns a paycheck
The Case 70XT is the XT-series Case skid steer that bridges the vintage 18-series simplicity and the alpha-series modern electronics. Cummins diesel reliability, hydrostatic dual-path service-friendliness, and modern-enough cab ergonomics make it a working machine on contractor yards today. Parts coverage stays strong because of the sheer volume of Cummins 4B engines produced and because the XT-series shares so many components across the Case skid steer family.
Maintenance priorities on a 70XT: clean fuel and quality filtration on the Cummins, hydraulic oil at temperature, drive-chain tension, cylinder seal replacement, and brake/control linkage service. Broken Tractor maintains parts coverage across the XT-series and the broader Case skid steer family.
