Part of the Kubota Parts Manuals.
Every part on the Kubota L4150DT traces back to one OEM number, and this catalog is where you find it. Its 275 pages tie each assembly to that number, matching what's already bolted to the tractor. Engine coverage spans from crankcase through injection pump, governor, and water pump. The drivetrain covers transmission shafts, rear differential, and PTO. The hydraulic section includes the draft control valve, shuttle valve, and 3-point linkage. Each exploded view ties a reference number to its part description, quantity, and factory weight. Need the fuel filter assembly? It's 19271-43010; the air cleaner is 17381-11010, the factory part rather than a generic stand-in. Bookmarks by system let you open the file on your phone at the parts counter and order right the first time.

Kubota L4150DT Common Problems This Manual Covers
Hard starting, rough idle, or power loss under heavy load on the L4150DT
Start at the fuel filter section on page 175. Swap the whole unit for ASSY FILTER FUEL part #19271-43010, or if only the internal element is gone, the exploded view on page 177 lists ELEMENT FILTER part #15521-43160. Confirm your fuel lines match the diagram before ordering.
Manual Section: Fuel Filter p. 175Main hydraulic system and three-point lift feel weak, operate with jerky movements, or will not lift
Check the suction oil line diagram on page 206. Locate the hydraulic filter assembly to identify the correct replacement components. Order COMP.FILTER OIL part #36330-82630 listed on page 207 to restore proper fluid flow. Inspect the surrounding O-rings and clamps in the diagram for wear.
Manual Section: Hydraulic Oil Line (Suction) p. 207Engine misfires and blows black smoke indicating worn injector nozzles or leaking delivery lines
Pull up the nozzle and glow plug breakdown on page 34 and match it to your engine configuration. Worn injectors swap out via ASSY NOZZLE part #17331-53000 on page 35. Cross-reference the injection pipes and clamps before ordering so the fuel system seals completely.
Manual Section: Nozzle and Glow Plug p. 35Heavy dust environment causing severe air restriction and engine choking under heavy load
Examine the double air cleaner schematic on page 224. Identify the primary cleaner housing and mounting bands. Order the complete replacement ASSY CLEANER AIR part #17381-11010 listed on page 225. If reusing the housing, secure the inner element part #68335-43620 shown on page 227.
