Part of the Kubota Parts Manuals.
Exploded-view parts lists fill the catalog's bookmarked, searchable pages, organized system by system. Start at the crankcase (50 kgf, page 8) and work through piston and crankshaft assemblies, the HST hydrostatic unit, front differential, 3-point linkage, and ROPS. Every numbered part sits in its own callout, so you can pin down what you need before calling a dealer. Hydraulic coverage goes deep: suction and delivery lines, steering circuits, HST oil circuits, control and relief valves, plus the cylinder and lift arm assembly, each with its own exploded view, part numbers, and quantity columns. I/C codes and serial number applicability (S.No.) run along every page, confirming which part fits your build. Bookmarked by system and keyword-searchable on any device. Pin down the part number, place the order, get back to work.

Kubota B2910HSD Common Problems This Manual Covers
Kubota B2910HSD loses drive or slips under load, need correct HST and transmission component part numbers
Open the HST Component Parts diagram at page 173. Differential-side shims come in 0.5mm and 0.2mm thicknesses (page 174), so measure your existing shim stack before ordering. Cross-check the Transmission Case section at page 160 and the Propeller Shaft diagram at page 169 to catch every drivetrain part tied to the loss of drive.
Manual Section: HST [Component Parts] p. 173Engine teardown reveals worn pistons and crankshaft bearings, can't identify correct oversize replacement part numbers
Refer to the Piston and Crankshaft diagram at page 30. Oversize pistons run +0.5mm; crankpin bearings come in -0.2mm and -0.4mm undersizes, so match the size to your bore measurement before ordering. The Lower Gasket Kit at page 79 lists the full bottom-end seal set to order alongside new bearings.
Manual Section: Piston and Crankshaft p. 30Engine cranks slowly or won't start, need starter motor assembly and component part numbers
Locate the Starter diagram at page 116, where the complete ASSY STARTER (3.2 kgf) is listed for a full swap. For a rebuild, flip to the Starter Component Parts exploded view at page 119, which breaks out brushes, solenoid, and drive gear. Also review the Stop Solenoid section at page 106, since a failed solenoid mimics starter failure.
Manual Section: Starter p. 116Injection pump removed for rebuild, need correct fuel injection component part numbers and pump assembly
Check the Injection Pump diagram at page 39. The complete pump assembly (ASSY PUMP INJECTION, 1.38 kgf) appears at page 40; for seals and individual components, see the Nozzle Holder Component Parts at page 52 and the Fuel Pump (Mechanical) section at page 56. Verify line fittings against the Fuel Pipe diagram at page 88.
Manual Section: Injection Pump p. 39Radiator leaking or overheating parts needed, can't find correct radiator and water pump part numbers
Start with the Radiator diagram at page 98 (non-Au) or page 101 (Au). The complete ASSY RADIATOR is listed at 3.5 kgf (page 100). Review the Water Pump section at page 60 and Water Flange and Thermostat at page 58 to round up every cooling-circuit part before you order.
Manual Section: Radiator [Except [Au]] p. 98Frequently Asked Questions
What are the torque specs for Kubota B2910HSD wheel bolts or lug nuts?
Part numbers, quantities, and weights for front and rear wheel bolts are listed here, but torque specs are not. For torque values, you'll need a separate service manual. p. 356
What are the replacement specifications for filters?
Oil filter replacement is ASSY CARTRIDGE OIL, part number 16271-32092, weighing 0.4 kgf (0.88 lb). Fuel filter is ASSY FILTER FUEL, part number 6A320-58862, at 0.09 kgf (0.198 lb). p. 23
What are the replacement specifications for hydrostatic transmission components?
HST components are listed with part numbers and weights. ASSY HST (part number 6C150-11603) weighs 16 kgf (35.2 lb); BEARING BALL (part number 37410-57190) weighs 0.14 kgf (0.308 lb). Differential-side shims come in 0.5mm and 0.2mm thicknesses. Detailed replacement procedures are not included; this is a parts identification catalog only. p. 174
How quickly can I access this manual after buying?
Instant PDF download. The full 404-page searchable Parts Catalog lands in your hands right after payment. Open it on a laptop, tablet, or phone, right at the bench.
Can I print specific sections of this Kubota B2910HSD Parts Catalog?
No DRM or copy protection. Print the whole catalog or just the pages you need. Any home or office printer works.
Does this Kubota B2910HSD catalog cover the hydraulic system parts?
Yes. It has exploded parts views and part numbers for the hydraulic groups, suction lines, delivery lines, steering circuit, HST oil lines, control and relief valves, and the cylinder and lift-arm assembly, so you can identify and order the right components. It's a parts breakdown, not a hydraulic circuit drawing.
