Part of the Kubota Parts Manuals.
Tracking down factory part numbers for your tractor is simple with this 247-page kubota l2500dt parts catalog pdf. It maps every major assembly, including the engine, drivetrain, hydraulics, electrical system, chassis, and hitch. The manual dedicates 48 pages to engine exploded views, running from the crankcase (weighing 48.5 kgf / 106.7 lb) and piston/crankshaft through the injection pump, governor, and gasket kits. Drivetrain diagrams cover the main shaft, countershaft, PTO shafts, rear differential, and three rear wheel size options. Hydraulic sections span the pump, position and draft control valve variants (both using a 0.40MM shim), and the complete 3-point linkage. Electrical diagrams catalog the 40A fusible link and 10A/15A fuse ratings. Stop guessing at the parts counter. This bookmarked, keyword-searchable file lets you verify the exact component on your phone before ordering.

Kubota L2500DT Common Problems This Manual Covers
Kubota L2500DT front wheel drive won't engage, looking for propeller shaft coupler part number p. 155
Review the Propeller Shaft exploded view on page 155 to identify the front coupler assembly and its part number. Verify the Front Wheel Drive Case diagram on page 157 for mating components. Note the differential gear shaft shim listed at 0.40MM on page 150; order that alongside the coupler if the shaft shows wear.
Manual Section: Propeller ShaftEngine cranks slowly or won't start, need correct fuse and relay part numbers p. 94
Trace the start circuit using the Electrical Wiring diagram on page 94. Check the Switch section on page 88 for key switch and relay part numbers. Verify the fuse section on page 95: the circuit uses 10A and 15A blade fuses plus a 40A fusible link; confirm which have blown before ordering replacements.
Manual Section: Electrical SystemAlternator not charging, need assembly or component part numbers for replacement p. 78
Examine the Alternator section on page 78 to identify the complete assembly part number. The assembly weighs 2.97 kgf, listed on page 79; use that figure alongside the part number to confirm you have the correct replacement unit. For brushes, rectifiers, or bearings, turn to the Component Parts diagram on page 80.
Manual Section: AlternatorHydraulic pump worn or seized, need pump assembly or rebuild component part numbers p. 185
Consult the Hydraulic Pump diagram on page 185 for the complete pump assembly part number. For internal seals and components, check the Hydraulic Pump Component Parts section on page 187. If sourcing control valve parts at the same time, the position control shim is listed at 0.40MM on page 196; confirm your valve variant before ordering.
Manual Section: Hydraulic SystemWater pump leaking coolant from weep hole, need replacement assembly part number p. 34
Reference the Water Pump exploded view on page 34 to pull the correct assembly part number. The complete pump assembly weighs 1.21 kgf (2.662 lb), confirmed on page 35; verify that weight against your unit before ordering. Also check the Water Pipe section on page 70 for associated hose and fitting part numbers.
Manual Section: Cooling Water SystemFrequently Asked Questions
What are the replacement specifications for front coupler on the propeller shaft?
The front coupler on the propeller shaft uses part number T0070-14710. Two units are required. Detailed replacement specifications beyond the part number are not provided in this catalog.
What are the replacement specifications for fuses?
This manual lists two types of fuses: a 10A fuse (Part No. 31351-33630, quantity 4) and a 15A fuse (Part No. 31351-33640, quantity 2). These amperage ratings are the primary replacement specifications.
My L2500DT front wheel drive won't engage, what parts should I look at?
Start with the Propeller Shaft exploded view to identify the front coupler assembly, then check the Front Wheel Drive Case diagram (page 157) for the mating components. The Differential Gear Shaft section lists a 0.40MM shim (page 150), if the shaft shows wear, order that alongside the coupler. This catalog gives you the part numbers and diagrams to source those components (page 155).
Does this manual help me rebuild or replace a worn hydraulic pump on the L2500DT?
Yes. The Hydraulic Pump diagram gives the complete pump assembly part number (page 185), and the Hydraulic Pump Component Parts section breaks out the internal seals and components (page 187). If you are also servicing the control valve, the position control shim is listed at 0.40MM (page 196), confirm your valve variant before ordering.
Where do I find the water pump part number if mine is leaking coolant?
The Water Pump exploded view gives the correct assembly part number for a pump leaking from the weep hole (page 34). The associated hoses and fittings are in the Water Pipe section (page 70), so you can order the pump and its connecting parts together.
My alternator isn't charging, can I get individual component parts or only the whole assembly?
Both. The Alternator section gives the complete assembly part number (page 78), and the Alternator Component Parts diagram breaks out the brushes, rectifiers, and bearings if you only need internal pieces (page 80). This lets you decide between a full assembly swap and an internal repair.
