John Deere 310J Backhoe Loader: J-Series Tier 3 Mid-Class
Produced from 2007 to 2011, the 310J built on the 310 legacy with an EPA Tier 3-compliant PowerTech diesel, improved hydraulic performance, and enhanced cab ergonomics. Built for contractors needing durability, smooth operation, and modern operator-experience refinements without the aftertreatment complexity that came in the Tier 4 generations.
Where the 310J fits in the JD backhoe line
The 310J succeeded the 310G as the mid-class industrial backhoe loader in JD's lineup. Production ran from 2007 through 2011, with the Super-J variant (310SJ) running alongside as the heavier-duty option in the same chassis family. The J refresh brought EPA Tier 3 emissions compliance and a cab refinement pass focused on operator ergonomics.
Tier 3 on a backhoe of this class means a refined fuel system, electronic engine control, and cooled EGR - but still no DPF, no DEF, and no SCR. The Tier 3 engine is materially simpler to service than the Tier 4 K and L generations that followed, while still delivering the modern operator workflow customers expected from a late-2000s machine.

What changed from the 310G to the 310J
- Engine. EPA Tier 3 JD PowerTech diesel. Refined fuel system with electronic engine control, cooled EGR, and updated emissions calibration.
- Hydraulic performance. Improved hydraulic flow distribution and pump efficiency. Smoother control response across both loader and backhoe circuits.
- Cab ergonomics. Enhanced operator station - refined seat, improved climate control, updated gauges and monitor display, reorganized controls.
- Service access. Refined daily-service points and fluid sampling locations.
- Electrical and electronics. Updated harnesses, sensors, and control modules to support Tier 3 engine control.
Engine, hydraulics, and drivetrain
The 310J's PowerTech Tier 3 diesel drives a refined power shuttle transmission into planetary final drives. The engine adds incremental electronic sophistication over the 310G - refined ECU calibration, updated sensors, and more precise injection timing - but the overall service profile is similar.
The implement hydraulic circuit feeds both the front loader and the center-pivot backhoe through a refined control valve stack. Loader cylinder bore and stroke vary with bucket configuration; the backhoe carries standard reach and extendable-dipper options. Drivetrain choices included 2WD and 4WD/MFWD axle configurations.

Need a part for your John Deere 310J Backhoe Loader?
PowerTech Tier 3 engine components, common-rail fuel system parts, and hydraulic seal kits are the most common service requests on the 310J. Call our parts team with your serial number.
Request a PartWhat to verify before ordering
- Serial number. The 310J had running changes through its production. Match parts to the machine serial.
- Engine serial. PowerTech Tier 3 internal parts must match the engine serial.
- Tier 3 emissions configuration. Confirm cooled-EGR setup, ECU calibration, and common-rail fuel system components against engine serial.
- Power shuttle revision. Shuttle clutch pack designs saw mid-run revisions.
- Loader configuration. Standard, quick-attach, and specialty bucket configurations had different cylinder and mounting specs.
- Backhoe configuration. Standard reach vs. extendable boom configurations differ in cylinder bore and stroke.
- Drivetrain configuration. 2WD and 4WD/MFWD configurations have different front axle and transfer case parts.
- Cab vs. ROPS canopy. Glass, weather seals, A/C parts, and door parts differ.
Why the 310J remains a strong used-machine pick
The 310J is the sweet-spot used 310 for customers who want a modern operator experience without Tier 4 aftertreatment service requirements. Tier 3 PowerTech engine with broad parts support, refined power shuttle drivetrain, improved hydraulics, and a cab that meets late-2000s operator-comfort expectations.
Maintenance priorities on a 310J: clean fuel (Tier 3 common-rail doesn't tolerate contamination), power shuttle fluid changes on schedule, hydraulic seal replacement as cylinders age, swing tower pin service, and engine rebuilds when wear demands. Broken Tractor maintains parts coverage across the full 310 family.
