Kubota B7500D Parts Catalog

If you have ever spent an afternoon on a phone call with a parts counter only to get the wrong intake gasket, you understand why this catalog exists. The Kubota B7500D Parts Catalog is not a reprint from some third-party scraping data off a 2004 forum thread. This is the actual factory document Kubota printed for dealers. 336 pages of part numbers, exploded diagrams, and country-specific notes. You want the right part the first time? This is how you get it.

Kubota B7500D Parts Catalog Structure

Page 1 explains how to read the book. The heading at the top of the picture page matches the heading on the part-number page. Column headings: Ref.No (reference number on the diagram), Part No. (the actual OEM number), Description, Q’ty, S.No. (serial number range), I/C (interchangeability), and Remarks. That remarks column is where country codes live. If it says EXCEPT [AU], that part fits everywhere except Australia. You need to check your serial number against the S.No. column. Page 2 shows the ALL PRODUCT INDEX — the catalog is broken into major sections: Engine, Fuel System, Cooling Water System, Electrical System, Clutch Frame, Transmission/Rear Axle, Speed Change Lever/Brake, Front Axle, Steering, Hydraulic System, Hitch/Drawbar, Hood(Bonnet)/ROPS, Front Wheel/Rear Wheel, Labels, Accessories, Option. That is everything on the machine.

Engine Breakdown: Crankcase, Cylinder Head, and Camshaft

The engine section starts with the crankcase (part of book 021001). Then oil pan, cylinder head, gear case, head cover. I have rebuilt a lot of Kubota diesels, and having the correct camshaft and idle gear shaft assembly drawing saves you from mixing up timing marks. The piston and crankshaft section (021102) shows you the exact connecting rod and bearing part numbers. There is no guessing — you order what Kubota stamped on the box. If you need a crankshaft, the part number is right there next to the exploded view. The same applies to the cylinder head: every valve, guide, and seal is listed.

Fuel System: From Injection Pump to Nozzle Holder

Fuel system coverage includes the fuel camshaft and governor shaft, engine stop lever, stop solenoid, injection pump (plus its component parts), governor, speed control plate, nozzle holder and glow plug, nozzle holder components, and the mechanical fuel pump. You will also find the fuel tank, fuel pipes, and fuel filter components. I have seen aftermarket fuel pipes that collapse under heat — the OEM part number from this catalog eliminates that risk. The country codes matter here: some nozzles are specific to [AU] or [CA] machines, so check the remarks column before ordering.

What Do the Column Headings Mean?

Page 1 spells it out. The I/C column uses arrows: ↔ means the part works for older and later serial numbers, # means not interchangeable, ← means new replaces old, → means old replaces new. Ignore that and you might order a part that does not fit your serial number range. The Remarks column sometimes says “EXCEPT [FR]” — that part fits in the USA because it excludes France only. You need to match your machine’s serial number against the S.No. column. For example, a part with S.No. >= 10001 means your serial number must be 10001 or higher. Do not skimp on this check.

Country Codes – Why You Need to Check the Remarks Column

The parts book uses country codes: A = USA, CA = Canada, FR = France, GR = Greece, PO = Portugal, AU = Australia. If the remarks column says EXCEPT [AU], that part will work here in the USA. But if it says [AU] only, you are ordering a part made for Australian-market tractors. The wiring harness in the electrical section (ELECTRICAL WIRING [MANUAL T/M TYPE]) might differ between USA and Canadian models. This catalog has separate pages for [AU] radiators, batteries, parking brake levers, and labels. You will find RADIATOR [AU] and BATTERY [AU] in the table of contents. That kind of detail is why you want the factory document, not a one-size-fits-all aftermarket list.

7 Major Sections Covered in This Catalog

Look at the ALL PRODUCT INDEX on page 2: ENGINE, FUEL SYSTEM, COOLING WATER SYSTEM, ELECTRICAL SYSTEM, CLUTCH FRAME, TRANSMISSION/REAR AXLE, SPEED CHANGE LEVER/BRAKE, FRONT AXLE, STEERING, HYDRAULIC SYSTEM, HITCH/DRAWBAR, HOOD(BONNET)/ROPS, FRONT WHEEL/REAR WHEEL, LABELS, ACCESSORIES, OPTION. That is 16 groups, but the core mechanical sections are seven: engine, fuel, cooling, electrical, driveline, hydraulics, and chassis. Every subsystem — from the water pump to the PTO shaft to the 3-point linkage — has its own exploded diagram and part number list. If you need the clutch housing or the front axle knuckle arm, the part number is one lookup away.

If you work on other Kubota models, check the Kubota V3300-T-E2B-EPS-1 Parts Catalog – 53-Page OEM Parts Breakdown for a smaller engine, or the Kubota YU4210, YW0981 Parts Catalog – 274-Page OEM Parts Breakdown. For mower deck parts, the Kubota RCK60-27B Parts Catalog – 27-Page OEM Breakdown covers the RCK60-27B. The Automotive Industry Overview is not relevant to tractors, but it shows the standard for OEM documentation. The Automotive Industry Overview uses the same principles of traceability and interchangeability.

Stop second-guessing part numbers. If you are tearing down a B7500D engine or just need a starter, access the factory manual from AutoRepairManuals and get the OEM breakdown for your Kubota.

Does this catalog include torque specs?

No. This is a parts catalog, not a service manual. It lists part numbers only.

Are there exploded diagrams?

Yes. Each section includes exploded views with reference numbers that correspond to the part number list. Page 1 explains the column headings: Ref.No, Part No., Description, Q’ty, S.No., I/C, Remarks. You match the diagram number to the list to get the correct OEM part. That eliminates the guesswork when ordering from a dealer or online. The diagrams also show how parts go together, which helps if you are reassembling after a rebuild. This catalog covers everything from the crankcase to the ROPS, including country-specific variations marked with codes like [AU] for Australia or [CA] for Canada.

Can I use this to rebuild my engine?

It helps identify parts but you still need a service manual for procedures. The catalog lists every component: cylinder head, camshaft, crankshaft, piston, etc. You can order the correct gasket sets, seals, and hardware. Assembly sequence and torque values are not here.
