Kubota B7200HST Parts Catalog – What You Get With 168 Pages of Factory Parts Data

I have pulled a lot of parts catalogs apart over the years. Aftermarket garbage that lists a part number that doesn’t match the casting mark, or leaves out the seal kit you need. That costs you time and money. This Kubota B7200HST Parts Catalog is the real deal – an OEM factory document, 168 pages thick, that tells you exactly which part goes where, by serial number range. No guessing, no cross-referencing three different sites. You point to the exploded diagram, you read the column headers the way Kubota wrote them (page 1 explains how to read Reference No., Part No., Description, Qty, S.No., and I/C codes), and you order the right piece the first time.

Engine and Cylinder Head Breakdown

The catalog breaks the D850-LA-H and D950-LA-H engines into individual assemblies: crankcase, oil pan, cylinder head, gear case, main bearing case, cylinder head cover, manifold, valve/rocker arm, camshaft, piston/crankshaft, flywheel, injection pump, nozzle holder – it is all there. If you are rebuilding a top end, you need the exact cylinder head gasket and valve stem seal. This catalog lists them by part number and shows which serial number range they fit. The same logic applies to the complete engine bottom end – crankshaft, connecting rods, bearings. You get factory identification for every single component.

What Systems Are Covered in 168 Pages?

This isn’t just an engine catalog. Flip to page 2 and you see the ALL PRODUCT INDEX: transmission (including the HST case for the B7200HSTE(D)), clutch, rear axle/rear wheel, brake, front axle/front wheel, steering, hydraulic system, hood/chassis, labels, accessories. Each major group splits into sub-assemblies. For example, under TRANSMISSION you get the transmission case, case cover, 4th shaft, 2nd shaft, 3rd/5th and PTO shaft, rear differential, and the HST section. Every shaft, every seal, every bearing has a row with a part number.

3 Reasons to Use OEM Parts Catalogs

First, serial number accuracy. The catalog uses S.No. columns with arrows (→ your serial number must be greater or equal; ← less or equal). Aftermarket databases often ignore these. Second, interchangeability codes (I/C) tell you if a part works across serial ranges or is a one-way update. Third, country-specific notes – Kubota prints these catalogs with country codes (US, CA, FR, GR, etc.) so you don’t accidentally order a French-spec part. That level of detail is why a shop relies on OEM documentation. If you are working on a B7200HST, you need the same source the dealer counters use.

Verify Your Serial Number Before Ordering

Page 1 of the catalog explains the S.No. column syntax. If a part has a → 50000, your tractor’s serial number must be 50000 or higher. If it shows ← 60000, it must be 60000 or lower. The I/C column uses symbols ↔ (works for older and newer), # (not interchangeable). Do not skip this step. I have seen guys order a rear axle case for a B7200HST only to find out their serial number fell in a range that used a different casting – because they didn’t read the columns. This catalog hands you that information on every part page.

Transmission and HST: Factory-Coded Parts

The transmission section covers the B7200HSTE(D) transmission case, case cover, clutch rod, clutch, and all shafts (4th, 2nd, 3rd/5th/PTO), plus the rear differential, rear axle, and hubs. The HST section is separate. If you are diagnosing a hydrostatic drive issue, you need the HST block, hydraulic block, and hydraulic pipe part numbers. This catalog lists them under HYDRAULIC SYSTEM and HST. You also find the front axle arm, bevel gear case, front axle case, knuckle arm, front differential – all with OEM part numbers. For the front wheels (6-12 or 20.5-8.00×10) and rears (9.5-16 or 31×13.5-15) the tire sizes are in the description.

Who Needs This Catalog and Why?

Home garage enthusiasts who own a B7200HST and want to order exactly the right seal, gasket, bearing, or hydraulic fitting without paying dealer markup. You can look up a valve spring, a camshaft, a crankshaft pulley – whatever. If you are rebuilding the engine or transmission and need to source parts from multiple suppliers, having the factory part number means you get the correct aftermarket equivalent (if one exists) or buy genuine Kubota. Professional mechanics use this to quote jobs accurately and avoid returns. If you do not have a parts catalog, you are guessing. Guessing costs you twice the shipping and a weekend of downtime.

Source Validity: OEM vs. Aftermarket Parts Lists

This is a direct scan of the Kubota factory Parts Catalog. Not a third-party compilation. Kubota printed these for dealer use – the same document a parts counter pulls up. The structure is standard: each page has an exploded view on the left and a numbered table with Ref. No, Part No., Description, Qty, S.No., I/C, and Remarks. I do not trust aftermarket manuals for parts identification because they often skip the serial number columns, leaving you to guess whether a crankshaft fits a late-model engine. This catalog gives you the full data.

Does this parts catalog include torque specs or repair procedures?

No. This is a parts identification catalog, not a service manual. For torque specs and repair steps you need the workshop manual. We have that too: Kubota B6200HST B7200HST Workshop Manual.

How do I look up a cylinder head gasket for my B7200HST?

Go to the engine section under CYLINDER HEAD (01E003 in the index). Find your serial number range in the S.No. column and match it to the Ref. No. on the exploded diagram. The part number listed is the OEM gasket. If your engine serial number falls in a range marked with an I/C symbol #, the gasket is not interchangeable with earlier or later engines – order the exact one. The same process applies to every component from the valve/rocker arm assembly to the crankshaft bearing shells. The catalog is organized by assembly group, so you start with the major section (e.g., ENGINE, TRANSMISSION) and drill down to the sub-assembly. Each part number is unique to that specific serial range. You will also find country codes in the Remarks column – for example, EXCEPT [FR] means the part fits all markets except France. For US models like the B7200HST, you are safe with parts marked for (CA) – United States of America. If you need to cross-reference to another related model, check the Kubota V3300-T-E2B-EPS-1 Parts Catalog – 53-Page OEM Parts Breakdown or the Kubota YU4210, YW0981 Parts Catalog – 274-Page OEM Parts Breakdown if you work on multiple machines.

If you regularly work on a B7200HST, stopping to call a dealer for a part number every time you open a housing is a waste of billable hours. Access the Factory Manual, put it on your tablet or print the pages you need, and start ordering exactly what the tractor was built with. 168 pages, every seal, every gear, every bolt – identified by the source that knows the tractor best.
