Part of the Kubota Parts Manuals.
Need the right factory part number before you call the dealer? That's the single job these 581 pages do for the Kubota L3130DT, L3130GST, and L3130HST. Every major assembly gets an exploded-view diagram beside its numbered parts list, from the crankcase and piston-crankshaft group down to the HST unit's piston, regulator, and rotary component sets. Kubota's interchangeability symbols sit in each section, so you can tell at a glance whether a listed part crosses to your DT, GST, or HST variant. The electrical section splits fuse ratings by circuit (5A through 40A) and lists switch assemblies separately for each transmission, pointing you to the exact harness or relay number you're after. Three variants, one catalog, so cross-checking takes seconds. Bookmarked by system and searchable by keyword, it pulls up fast on a tablet to confirm the number and order it once.

Kubota L3130DT, L3130GST, L3130HST Common Problems This Manual Covers
Kubota L3130HST loses drive power and struggles under heavy load with extremely dirty hydraulic fluid. p. 358
Check the hydraulic oil line inlet diagrams on page 358. Locate the 0.535 kgf oil filter assembly and its mounting bracket. Cross-reference the filter cartridge part numbers for your specific HST type serial number before ordering a replacement to ensure proper fluid flow.
Manual Section: Hydraulic Oil Line(Inlet) [Hst Type]Engine cranks but won't start, or catches only intermittently, when fuel delivery falls short. p. 40
Trace the engine stop lever components on the page 40 diagram. The 0.29 kgf fuel shutoff solenoid and its mounting hardware are called out there; confirm the solenoid assembly's part number in the matching parts list so it fits your engine configuration.
Manual Section: Engine Stop LeverTractor engine stalls unexpectedly or safety interlocks shut the machine down during standard field operation. p. 109
Inspect the switch and relay diagrams on page 109. The 0.07 kgf relay assembly sits with its connector block; read off the component reference numbers and match them against the parts index so the replacement relay fits your safety interlock circuit.
Manual Section: Switch/Relay [Rops Type]Diesel runs down on power and stalls without warning once fuel flow gets choked off. p. 84
Open to the fuel filter breakdown on page 84. Note the 0.59 kgf filter element and its sealing O-rings, then look up their part numbers in the table to get the right replacement element and bring fuel flow back.

The [GST Type] adds a 10A (Part No. T1060-30440).
What are the replacement specifications for relays?
The SWITCH/RELAY [ROPS TYPE] section calls out two relays: RELAY GLOW Part No. T1060-33710 (qty 2) and RELAY STARTER Part No. T1060-33720 (qty 1).
Which hydraulic oil filter part number applies to the L3130HST?
For HST hydraulic filter service, page 358 shows the 0.535 kgf hydraulic oil filter assembly on the inlet line. Cross-reference the filter cartridge part number for your HST type serial number before ordering to ensure correct fluid flow.
What fuel filter part should I order for a Kubota L3130 engine?
Page 84 of the Fuel Filter [Component Parts] section shows the 0.59 kgf fuel filter element with sealing O-rings. Look up the part numbers in the accompanying table to identify the correct replacement element for your engine configuration.
