Case TR310B Compact Track Loader: Alpha-Series Radial-Lift CTL
The Case TR310B is part of Case’s alpha-series TR (radial-lift) compact track loader range — Tier 4 Final compact diesel, hydrostatic dual-path drive on a tracked undercarriage, and the alpha-series cab. Radial-lift geometry on a CTL chassis gives the flotation of tracks with the ground-level reach pattern of a radial-lift loader.
Where the TR310B fits in the Case skid steer / CTL line
The TR310B sits in Case’s alpha-series TR (radial-lift) compact track loader range between the Case TR310 and the Case TR320. Tracked undercarriage, radial-lift loader geometry, Tier 4 Final aftertreatment. The TR-series sits alongside the TV-series (vertical-lift) CTLs and the SR/SV wheeled skid steers in the alpha-series family — same cab platform, same control architecture, different lift geometry and drive configuration.

Engine, hydraulics, and drivetrain
The TR310B runs a Tier 4 Final compact diesel through a hydrostatic dual-path drivetrain into a tracked undercarriage — closed-loop hydrostatic pumps drive final-drive motors at each track. Loader hydraulics use a load-sensing piston pump with electrohydraulic control valves. The CTL undercarriage gives the TR310B flotation on soft material that a wheeled skid steer can’t match.
Tier 4 Final aftertreatment on this generation means a DPF, an SCR catalyst, and DEF dosing — clean fuel and quality DEF are non-negotiable for long aftertreatment life. Track wear monitoring becomes the largest single recurring cost on a CTL chassis, so factor undercarriage replacement into the ownership plan.
Common service items on the TR310B
- 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, rollers.
- Bucket coupler hardware: 47396814K bucket pin kit cross-fits L216-L230, C232-C238, SR160-SR250, SV185-SV300, TV380, 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.

Request a PartWhat to verify before ordering
- Aftertreatment + undercarriage generation. Tier 4 Final aftertreatment configuration varies by build year; CTL undercarriage components (tracks, sprockets, idlers, rollers) saw revisions — confirm by serial.
- Serial number. Confirm the serial on the Case TR310B 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.
Why the TR310B still earns a paycheck
The Case TR310B is an alpha-series CTL for operations that need the flotation and ground-pressure profile of tracks with the ground-level reach pattern of radial-lift geometry. Landscape, sensitive turf, soft material, and any operation where wheels would sink — the TR310B keeps working.
Maintenance priorities on a TR310B: clean fuel and tight water separation, DPF regen behavior, hydrostatic charge pressure, and undercarriage wear monitoring (track tension, sprocket and roller wear, idler condition). CTL undercarriage life is the single largest recurring cost on this machine — service-life tracking matters. Broken Tractor maintains parts coverage for the TR-series alongside the broader Case alpha-series skid steer and CTL family.
