Case SR270B Skid Steer Loader: Alpha-Series Radial-Lift Tier 4 Final
The Case SR270B is part of Case’s alpha-series radial-lift skid steer range — Tier 4 Final compact diesel, hydrostatic dual-path drivetrain, and the alpha-series cab with electronic engine controls and modern operator ergonomics. Radial-lift geometry is optimized for dig-and-load work at ground level.
Where the SR270B fits in the Case skid steer line
The SR270B sits in Case’s alpha-series SR (radial-lift) skid steer range. Radial-lift loader geometry, Tier 4 Final aftertreatment, alpha-series cab, electrohydraulic joystick controls. The SR designation indicates radial-lift geometry — well-suited to ground-level dig-and-load duty cycles — while the B suffix marks the updated alpha-series build with Tier 4 Final emissions compliance.

Engine, hydraulics, and drivetrain
The SR270B runs a Tier 4 Final compact diesel through a hydrostatic dual-path drivetrain. Loader hydraulics use a load-sensing piston pump with electrohydraulic control valves and direct-acting cylinders. The radial-lift loader geometry gives a single-arc reach pattern — best matched to ground-level digging, loading trucks, and pallet work where the lift arc keeps the bucket out near the operator’s reach.
Tier 4 Final compliance is achieved via a DPF + DEF/SCR aftertreatment package and cooled EGR. Operators should expect periodic DPF regeneration cycles and need to keep the DEF tank topped with quality fluid to avoid SCR derate conditions.
Common service items on the SR270B
- 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.
- 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.

Request a PartWhat to verify before ordering
- Aftertreatment generation. Tier 4 Final configuration varies by build year - confirm DPF/DEF/SCR layout before ordering.
- Serial number. Confirm the serial on the Case SR270B before ordering year-specific parts.
- 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.
- Control configuration. Electrohydraulic joystick vs. hand-and-foot controls affect harness and valve part numbers.
Why the SR270B still earns a paycheck
The Case SR270B is an alpha-series radial-lift skid steer covering ground-level dig-and-load duty cycles, loading trucks, pallet work, and any application where the radial-lift geometry’s reach pattern fits the job. The Tier 4 Final powertrain meets current emissions requirements while the alpha-series cab gives operators a modern, sealed, climate-controlled station with electrohydraulic joystick controls.
Maintenance priorities on a SR270B: clean fuel and tight water separation for common-rail injection, DPF regen behavior, hydrostatic charge pressure, drive-chain tension, and cylinder seal replacement when leaks develop. Broken Tractor maintains parts coverage across the SR alpha-series.
