Tracking down factory part numbers for a Kubota D782-E2B-BHTU-1 engine is straightforward with this official PDF (OEM #YOOF2161). The 94-page manual covers every component from the crankcase to the muffler, including cross-compatibility for 4JH-DT, 4JH-DTZA, 4JH-DTZ, and 4JH-DTZY variants. Exploded views pair directly with numbered parts lists across 44 pages of engine sections, alongside dedicated breakdowns for the fuel, electrical, cooling, and intake systems. A numerical index at the back cross-references every item. If you are replacing a piston, oversize dimensions run +0.25mm, while crankpin bearing metals list down to -0.20mm undersize. Bookmarked by assembly and fully searchable, this file lets you pull the correct numbers right from your phone before calling the parts counter.

Kubota D782-E2B-BHTU-1 Common Problems This Manual Covers
Starter won't crank engine, need correct brush set and solenoid contact part numbers p. 57
Review the exploded view on page 57. The diagram breaks out the brush assembly, drive lever, and solenoid contact plate as individual line items. Cross-reference those numbers against the main Starter section on page 55 and confirm your serial number range before ordering.
Manual Section: Starter (Component Parts)Fuel filter part number unclear, unsure which element and bowl assembly fits this engine p. 45
Pull up the exploded view on page 45. The parts list separates the filter element, bowl, and sealing hardware. If your setup includes an electric lift pump, check the Fuel Pump (Electrical) section on page 47 to confirm all upstream components match.
Manual Section: Fuel FilterStop solenoid won't hold fuel open or won't cut off, need correct replacement part number p. 33
Examine the parts diagram on page 32. The list on page 33 shows the solenoid assembly and mounting hardware as separate line items. Confirm each number against your serial number range before ordering; the new solenoid part (16386-6001-2) is interchangeable for the old (16386-6001-0), but not vice versa.
Manual Section: Stop SolenoidGlow plugs failed on cold start, can't locate correct part number in catalog p. 39
Search the listings on page 39. The exploded view shows each plug individually alongside the nozzle holder assembly. If you also need nozzle holder adjusting washers, page 41 specifies thicknesses from 0.900mm to 1.950mm so you can confirm the correct shim.
Manual Section: Nozzle Holder and Glow PlugAir cleaner housing damaged, need exploded view to identify filter element and housing part numbers p. 79
Navigate to page 79. The diagram separates the housing, filter element, and mounting hardware with individual part numbers. This section carries an 'Old Parts' designation, so verify supersession status with your dealer before ordering, as current numbers may differ from what is printed.
Manual Section: Air CleanerInjection pump shim thickness unknown, need correct dimensions before sourcing replacement parts p. 35
Consult the parts list on page 35. Shim thicknesses are specified at 0.20mm and 0.25mm in the diagram. Identify which dimension applies to your engine variant before ordering. For related governor linkage hardware, the Speed Control Plate section on page 37 covers adjoining components.
