Kubota L3710DT, L3710GST, and L3710HST Parts Manual (P/N 100K0489)

• Covers 1999–2003 Kubota L3710DT, L3710GST, and L3710HST compact tractors, identifying exact part numbers for engine, transmission, hydraulic, and electrical systems.
• Official OEM publication P/N 100K0489, referencing 574 pages of exploded-view diagrams and component parts lists.
• Features 68 detailed component-assembly diagrams, mapping out the engine crankcase, cylinder head, injection pump, fuel system, and cooling loops.
• Includes complete parts breakdowns for the electrical wiring, panel board, Glide Shift Transmission (GST), Hydrostatic Transmission (HST), alternator, starter motor, and ROPS frame.
• Details individual components for the water pump, rear differential, steering cylinder, hydraulic pump, PTO clutch, shuttle shift lever, differential lock shift fork, and swinging drawbar.

Component Assembly Documentation

When you have a torn-down Kubota taking up space in the bay, you need accurate part numbers fast. This PDF parts catalog serves as the foundational reference for the L3710 drivetrain variants. The documentation provides a complete structural breakdown of internal engine components—from the oil pan and crankcase to the piston, crankshaft, and camshaft-drive idle gears. Detailed component views clearly illustrate the fuel injection pump, governor control linkages, nozzle holder assemblies, and intake/exhaust manifolds. Beyond the engine, the manual covers cooling system components, hydraulic control valves, and complete chassis elements like the front and rear axles, steering controllers, and 3-point linkage.

To assist with repair prep and diagnostic troubleshooting, the catalog includes electrical wiring diagrams, transmission case exploded-view drawings, steering cylinder schematics, panel board assembly charts, hydraulic oil line routing views, and front axle housing diagrams. While parts books do not contain written text procedures, the sequential sub-assembly views act as highly accurate visual teardown and reassembly guides. This allows you to successfully rebuild the hydrostatic transmission, overhaul the GST valve, split the tractor to access the PTO clutch, or rebuild the rear differential without relying on memory, saving you an expensive trip to the dealer.

Specification Highlights & Workshop Efficiency

Getting the right part the first time is critical for your shop's turnaround time. A major advantage of this manual is the inclusion of specific serial number breaks (S.No. =) alongside clear interchangeability charts (I/C). This ensures you order the exact revision for that specific production run, eliminating the risk of waiting days for a part that ultimately does not fit.

Always verify your specific serial number range against the provided charts to ensure safe and proper fitment. Installing mismatched components under heavy hydraulic load (system pressure rated at 2,500 psi / 17.2 MPa) can lead to equipment damage or severe safety hazards.

This catalog provides precise identification data, including the 97 cu in (1590 cc) engine displacement and peak crankshaft torque of 87 lb-ft (118 Nm). The standard ROPS-type fuel tank capacity is listed at 7.9 US gal (30 L).
