Kubota B7100HST-D, B7100HST-E Parts Catalog – 180-Page Factory Parts Breakdown

You’ve got a Kubota B7100HST-D or B7100HST-E sitting in the bay with a blown gasket, and you’re about to order parts. Stop. If you’re not using the factory Parts Catalog, you’re gambling – with time, with money, and with the next guy’s weekend. This 180-page OEM document is what Kubota shipped to dealers. No aftermarket shortcuts, no vague descriptions.

Engine Parts: Crankshaft, Cylinder, and Valve Coverage

Every major engine component is mapped with part numbers and serial number ranges. The Crankshaft section (listed under PISTON/CRANKSHAFT) shows exactly which assembly fits your tractor’s serial number – B7100HST-D >=60164 or B7100HST-E >=20025. Same for the Cylinder head, Valve rocker arm assembly, and Camshaft. You get the OEM part number, quantity, and interchangeability codes. Need a Fuel pump or injection pump? The FUEL PUMP and INJECTION PUMP sections break down every nut and seal. That kind of detail saves you from ordering a camshaft that doesn’t match the block.

Does This Parts Catalog Cover Fuel System Components?

Yes – and it goes deeper than most aftermarket lists. The catalog includes a full Fuel system subsection: FUEL PUMP, INJECTION PUMP with component parts, FUEL FILTER, FUEL TANK/ACCELERATOR LEVER, and the INJECTION PUMP [COMPONENT PARTS] page. Each line shows country-specific variants (e.g., EXCEPT [FR] for USA-market compatibility). The Instructions for Parts Books B7100HST-D explains how to read those column headers – you get the definition of part numbers, quantity, serial number range, and interchangeability arrows. That’s the difference between a part that bolts on and one that doesn’t.

3 Reasons to Trust OEM Documentation Over Aftermarket

First, the serial number columns. Aftermarket catalogs often skip the “S.No.” field, leaving you to guess if a part fits your build. Kubota stamps every engine and transmission with a serial number. This catalog lists exact ranges – for example, the CRANKCASE page specifies B7100HST-D >=60164. Second, the interchangeability codes (I/C column) tell you whether a part swaps backward or forward. Third, the country codes prevent ordering a part that only fits French or Australian market tractors. That’s real-world protection when you’re ordering a $400 crankshaft.

Get the Right Part Number the First Time

Flip to any section – CRANKCASE, OIL PAN, PISTON/CRANKSHAFT, MAIN BEARING CASE, FLYWHEEL, CYLINDER HEAD, VALVE/ROCKER ARM, NOZZLE HOLDER, CYLINDER HEAD COVER, INLET MANIFOLD, EXHAUST MANIFOLD, CAMSHAFT, GEAR CASE, FUEL PUMP, INJECTION PUMP, SPEED CONTROL PLATE, GOVERNOR – and you see the same layout. Part number, description, quantity, serial number, and interchangeability. No guessing. The 180 pages cover everything from the HST transmission to the steering knuckles. You’ll find exploded diagrams paired with the parts list so you can visually confirm what you’re ordering.

Camshaft and Valve Train: Factory Part Numbers

The Camshaft section (page referenced in the CAMSHAFT bookmark) includes the camshaft gear and key. The VALVE/ROCKER ARM section lists each valve, spring, retainer, and rocker arm assembly. If you’re rebuilding a cylinder head, you need those numbers. The Kubota V3300-T-E2B-EPS-1 Parts Catalog – 53-Page OEM Parts Breakdown covers a different engine family, but the same OEM rigor applies. For a full B7100 series breakdown, stick with this manual.

Who Needs This Parts Catalog?

If you’re a home garage mechanic working on a B7100HST-D or B7100HST-E, you want this on your tablet or printed out. Professional shop owners – hand it to the parts runner so they stop bringing back the wrong gasket. Tractor enthusiasts restoring a 1980s Kubota will use this to identify NOS parts or cross-reference to modern equivalents. The Kubota YU4210, YW0981 Parts Catalog – 274-Page OEM Parts Breakdown is another option for larger utility tractors, but for the B7100 series, this is the one.

Source Authenticity: OEM vs. Third-Party Copies

This is a scan of the original Kubota dealer parts book – not a re-keyed PDF full of typos. The file includes the “Instructions for Parts Books” page that explains how to read the columns and country codes. I’ve seen aftermarket parts lists that combine multiple models into one table and drop serial number ranges. That’s how you end up with a crankshaft that doesn’t fit. The Automotive Industry Overview from Wikipedia gives you context on how manufacturers manage part numbers, but nothing replaces the factory source. Automotive Industry Overview – same principle applies: standardization matters.

Frequently Asked Questions

Does this Parts Catalog include repair procedures or torque specs?

No. This is a parts identification catalog only – it lists part numbers, quantities, and interchangeability. For repair steps and torque values, you need the separate service manual.

How do I know if a part from the catalog fits my B7100HST-E with serial number 15000?

Check the S.No. column for each section. For most engine parts, the catalog shows B7100HST-E >=20025. If your serial is lower, the part may not fit. Use the interchangeability arrows (→, ←, ↔) to see if a superseded part works.

What do the country codes like [FR] or [CA] mean?

If the remarks column says “EXCEPT [FR]”, the part fits all countries except France. The catalog includes a country code legend on the first page – A for USA, CA for Canada, etc. Always check this before ordering, especially for fuel system parts that may have different emissions configurations.

Can I use this catalog to order parts for a different Kubota model?

Only if the part number is the same. The B7100HST-D and B7100HST-E share many components, but other models like the B7100DT use different blocks. Cross-referencing without this catalog is a waste of time.

Access the Factory Manual – get the exact part numbers, avoid return trips to the dealer, and keep your B7100 running with genuine OEM components. This 180-page Parts Catalog pays for itself on the first order you get right.
