Case TR340B Compact Track Loader: Alpha-Series Radial-Lift CTL
The Case TR340B 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 delivers the flotation of tracks with the ground-level reach pattern of a radial-lift loader.
Where the TR340B fits in the Case skid steer / CTL line
The TR340B sits in Case’s alpha-series TR (radial-lift) compact track loader range between the Case TR340 and the Case TV370. Tracked undercarriage, radial-lift loader geometry, and Tier 4 Final aftertreatment define the platform. The TR designation marks radial-lift CTLs; TV designations mark the vertical-lift counterparts that share the same alpha-series cab and powertrain core.

Engine, hydraulics, and drivetrain
The TR340B 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 TR340B flotation on soft material that a wheeled skid steer cannot match. Track wear monitoring becomes the largest single recurring cost on this machine — track chains, sprockets, idlers, and rollers all have finite service life and benefit from disciplined tension and wear tracking.
Common service items on the TR340B
- Engine internals: Tier 4 Final compact diesel - pistons, rings, sleeves, bearings, gaskets. Common-rail high-pressure injection on Tier 4 builds.
- Tier 4 aftertreatment: DPF service intervals, DEF tank and dosing module, SCR catalyst, EGR cooler service.
- Fuel system: Common-rail injectors, lift pump, 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.

Need a part for your Case TR340B Compact Track Loader?
Tier 4 aftertreatment, hydrostatic drive components, and CTL undercarriage are the highest-value items on a TR340B. Call our parts team with your serial number.
Request a PartWhat to verify before ordering
- Aftertreatment configuration. Tier 4 Final aftertreatment configuration varies by build year. Confirm DPF, SCR, and EGR part numbers against your machine’s aftertreatment serial tags.
- Undercarriage generation. CTL undercarriage components (tracks, sprockets, idlers, rollers) saw revisions across the TR340B run - confirm by serial.
- Serial number. Confirm the serial on the Case TR340B 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 TR340B still earns a paycheck
The Case TR340B is an alpha-series CTL for operations that need the flotation and ground-pressure profile of tracks combined with the ground-level reach pattern of radial-lift geometry. Landscape work, sensitive turf, soft material, and any operation where wheels would sink - the TR340B keeps working.
Maintenance priorities on a TR340B: clean fuel and tight water separation (Tier 4 common-rail injectors do not tolerate contamination), 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 across the alpha-series TR and TV CTL line.
