Case SV340B Skid Steer Loader: Alpha-Series Vertical-Lift Skid Steer
The Case SV340B is part of Case’s alpha-series vertical-lift skid steer loader range — Tier 4 Final compact diesel, hydrostatic dual-path drivetrain, and the SV vertical-lift geometry that gives operators more reach at full height for truck-loading and stacking work.
Where the SV340B fits in the Case skid steer / CTL line
The SV340B sits in Case’s alpha-series SV (vertical-lift) skid steer range. Vertical-lift loader geometry, Tier 4 Final aftertreatment, alpha-series cab, and electrohydraulic joystick controls combine to make the SV340B a stacking and truck-loading specialist. The B-suffix designation marks the second generation of the SV340 platform with refinements to the cab, controls, and aftertreatment system.

Engine, hydraulics, and drivetrain
The SV340B 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. The vertical-lift loader geometry keeps the bucket parallel to the chassis through the lift arc — best matched to truck-loading, stacking, and material handling where forward reach at full height matters.
The Tier 4 Final aftertreatment system combines diesel particulate filter (DPF), exhaust gas recirculation (EGR), and selective catalytic reduction (SCR) with diesel exhaust fluid (DEF) dosing. These systems are reliable when fed clean fuel and quality DEF, but they require attention — DEF tank must stay topped up, the DPF will request periodic high-temperature regens, and NOx sensors can fail and trigger derate conditions.
Common service items on the SV340B
- 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, 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.
- Bucket coupler hardware: 47396814K bucket pin kit cross-fits L216–L230, C232–C238, SR160–SR250, SV185–SV300, TV380, TR270–TR340 — high-volume coupler service kit.
- Hardware: 191048A2 axle stud & nut cross-fits broadly across the Case skid steer line.

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 SV340B 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 SV340B still earns a paycheck
The Case SV340B is an alpha-series vertical-lift skid steer for truck-loading, stacking, and material-handling duty cycles where forward reach at full height matters more than radial-lift’s ground-level reach pattern. The vertical-lift geometry combined with the alpha-series cab and electrohydraulic controls makes it a comfortable and productive machine for full-shift operation.
Maintenance priorities on a SV340B: clean fuel and tight water separation, DPF regen behavior, hydrostatic charge pressure, drive-chain tension, and cylinder seal replacement when leaks develop. Broken Tractor maintains parts coverage for the alpha-series skid steer family across Case and New Holland badging.
