1999–2003 Kubota L3710DT, L3710GST, and L3710HST Tractor Parts Manual (P/N 100K0489)

Kubota parts book 100K0489 covers the 1999–2003 L3710DT, L3710GST, and L3710HST compact tractors in ROPS configurations. Exploded assembly views are paired with part numbers, quantities, serial-number applicability, and interchangeability notes.

Text search and navigation: Headings and parts tables are searchable, with 250 embedded bookmarks for the index and component sections. Some annotations within illustration details are not searchable.

• Engine components: Parts breakdowns for the crankcase, cylinder head, piston and crankshaft, camshaft and idle gears, and engine oil pan.

• Fuel and cooling: Fuel injection pump, governor control linkages, nozzle holder, water pump, thermostat, radiator, fuel filter, and old/new air-cleaner parts.

• Transmission and PTO: Variant-specific transmission cases, GST valve and HST component breakdowns, PTO clutches, shuttle shift lever, and differential lock shift forks.

• Hydraulics and steering: Separate hydraulic pump assemblies, control valves, oil line routing views, steering controller, and steering cylinder exploded views.

• Electrical assemblies: Wiring harness layouts and parts lists, panel board assemblies, alternator and starter motor internals, and old/new switches.

• Axles and chassis: Front axle case and rear differential exploded views, brake assemblies, 3-point linkage, ROPS frame, wheels, and swinging/clevis drawbar options.

Suited to mechanics and experienced owners who can identify their tractor's configuration and use illustrated parts lists when planning a repair.

Engine Parts and Fuel-System Revisions

For an engine repair, the piston and crankshaft lists distinguish standard and oversize pistons and rings, undersize bearings, and oversize thrust washers. Upper and lower gasket kits are itemized, along with intake and exhaust manifold components.

The injection-pump lists distinguish non-interchangeable shim revisions at S.No. =2J0001, so matching thickness alone does not establish fitment.

DT, GST, HST, and PTO Configurations

Manual transmission, Glide Shift Transmission (GST), and Hydrostatic Transmission (HST) parts are handled separately, with distinctions for independent PTO, mid-PTO, and creep gearing.

HST views identify pump and motor assemblies, the swash plate, port-block cover, and regulator. Mid-case versions divide at S.No. =70001; the HST assembly and regulator change again at 74337/74338, with the later revisions marked non-interchangeable.

Coverage limit: The GST Range Gear Shaft entry, reference 01D11702, appears in the index, but its illustrated parts section is absent from this PDF.

Hydraulic Pumps, Control Valves, and Options

Non-HST hydraulic pump assembly 34550-36400 and HST assembly TA240-36400 have separate component lists. Control-valve breakdowns distinguish versions through S.No. 72128 and from 72129 onward.

Inlet, delivery, power-steering, and PTO oil line views identify the associated pipes, fittings, and seals. Optional draft-control linkages and remote control valve levers and couplers have dedicated parts sections.

Electrical Harness Versions

HST harness pages distinguish S.No. =70001; non-HST harness pages divide at 51803/51804.

The electrical illustrations show harness placement and replaceable components. They do not include circuit schematics, connector pinout tables, or electrical fault-finding procedures.

Serial Breaks, Interchangeability, and Repair Scope

The S.No. and I/C columns separate serial applicability from two-way interchangeability, one-way replacement, and parts that do not interchange. These markings help match the revision before ordering a replacement; the listed limits apply to the particular assembly or part.

Country codes distinguish U.S. [A] and Canadian [CA] label applications. ROPS parts are split at S.No. 72536/72537.

Parts illustrations support repair planning; this catalog does not contain teardown sequences, overhaul instructions, torque specifications, or hydraulic test pressures. Hydraulic, brake, and PTO work requires the applicable service instructions and safety precautions.
