Matching a factory part number before you call the dealer is the whole point of this Kubota B7510HSD Parts Catalog (OEM #100K0780). Its 348 pages break down into 169 pages of master parts lists, 55 pages of engine component diagrams running from crankcase to injection pump and governor, and 22 pages of drivetrain exploded views across the HST, transmission case, clutch shaft, and PTO. Wiring diagrams cover three regional variants (North America, Australia, New Zealand), with front and rear wheel configurations for six tire sizes. The fuse chart confirms a 30A main fuse and auto fuses at 5A, 10A, 20A, and 30A. Match any reference number against a clean diagram instead of a worn paper list. Everything is bookmarked by system and searchable by keyword, so you can pull a part number on any device right at the machine.

Kubota B7510HSD Common Problems This Manual Covers
Kubota B7510HSD hydrostatic transmission has no forward or reverse drive, need HST internal component part numbers p. 140
Open the HST Component Parts exploded view on pages 140-145 to identify individual internal components and their part numbers. Check the Transmission Case diagram on page 128 to confirm drivetrain context. If the hydraulic pump (PS) is also involved, find it on page 222; the pump assembly weighs 11.1 kgf, so confirm your serial-range part number before ordering.
Manual Section: HST [Component Parts]Engine cranks slowly or won't crank at all, need starter assembly and solenoid component part numbers p. 91
Find the complete starter assembly part number in the Starter exploded view on page 91; the unit weighs 2.75 kgf. For internal components including brushes and the drive assembly, open Starter Component Parts on pages 93-95. If the fault is in the fuel shutdown circuit rather than the starter, cross-reference the Stop Solenoid parts on page 84.
Manual Section: StarterSafety switches or dashboard electrics fail intermittently, need correct fuse and switch part numbers to replace p. 112
Pull the Electrical Wiring diagram on page 112 to trace the affected circuit, then check page 113 for confirmed fuse ratings: 5A, 10A, 20A, and 30A variants are specified. Locate fuse and switch part numbers in the Switch exploded view on page 98. For safety interlock components, check the Panel Board Component Parts diagram on page 102.
Manual Section: Electrical WiringEngine overheating under load, need radiator assembly, fan, and coolant pipe replacement part numbers p. 78
Locate radiator part numbers on page 78 for North American and Canadian markets, or page 80 for all other markets. The radiator assembly weighs 2.5 kgf; confirm the correct regional variant before ordering. Find fan blade assembly parts on page 74 and coolant hose hardware on page 76. For the reserve tank and overflow components, check page 82.
Manual Section: Cooling System ComponentsTractor won't start after sitting, fuel delivery suspected, need fuel filter component and pipe part numbers p. 72
Start at the Fuel Filter Component Parts diagram on page 72 to identify individual filter sub-parts and their part numbers. Trace connecting fuel pipe hardware on page 70. For the fuel tank and cap assembly, check page 68. The injection pump shown on page 34 weighs 1 kgf; if the pump is also suspect, cross-reference its component list before ordering.
