Kubota B1750HST-D Parts Catalog – 304 Pages of Factory OEM Part Numbers

You know the drill. You pull a Kubota B1750HST-D Parts Catalog job, find a cracked cylinder head or a worn camshaft, and then spend half an hour flipping through aftermarket websites trying to match a part number from a blurry photo. Waste of time. That noise stops when you have the factory OEM parts catalog sitting open on the bench. This is a 304-page document – not a reprint, not a summary, but the actual book Kubota dealers used to order parts. Every exploded view, every reference number, every part number stamped directly from the original print.

The thing about parts catalogs is, they tell you exactly what fits – and what doesn’t. That matters when you’re ordering a piston/rods assembly for a D1302 engine or a nozzle holder for the injection pump. The catalog organizes everything by functional groups: crankcase, oil pan, piston/crankshaft, main bearing case, flywheel, Cylinder head, Valve/rocker arm, Camshaft, gear case, water pump, Fuel pump, injection pump, and on down the line. You get the Kubota factory part number, the quantity used, and serial number range for interchangeability. No guesswork.

Engine Section: Crankshaft, Cylinder Head, and Valve Train

Open to the Engine index and you’ll find the whole top end and bottom end laid out. The CRANKCASE group (call it section 01T001) shows the block, bearings, and seals. Right below it, PISTON/CRANKSHAFT covers rods, pistons, rings, and the crankshaft itself. CYLINDER HEAD and VALVE/ROCKER ARM sections break down the head gasket, valves, seats, springs, rocker arms, and pushrods. Want to replace the camshaft? It’s listed under CAMSHAFT with its own reference number and part number. I’ve seen guys buy the wrong valve because they eyeballed it off a picture – this catalog kills that gamble.

Page 2 of the catalog’s all-product index shows the entire system codes. Every engine component is grouped under one common page index – you don’t have to bounce between unrelated sections. The book’s organization follows the Automotive Industry Overview logic of grouping by major assemblies. Saves time when you’re standing at the counter at the dealer or placing an order online.

Fuel System and Injection Pump Coverage

Fuel system on the B1750HST-D is not something you want to guess on. The catalog covers FUEL PUMP, INJECTION PUMP (including component parts), FUEL TANK, FUEL PIPE, and FUEL FILTER component parts. Each injection pump component has its own exploded view with screws, springs, plungers, and delivery valves. The nozzle holder section gives you both the holder assembly and the component-parts breakdown – crucial when you’re replacing nozzles or shims. Country codes in the remarks column indicate whether a part is specific to USA, Canada, or other markets. Example: if it says EXCEPT [FR], that part works in the US but not in France. Clean.

3 Systems Covered in Detail

The catalog splits the tractor into three major zones: engine & fuel, drivetrain & hydraulics, and chassis/electrical. Under drivetrain you get CLUTCH, HST (hydrostatic transmission with component parts), transmission case, propeller shaft, rear differential, brake system, front axle case (with and without Bi-Speed Turn), front differential, and all the bevel gear and shaft sections. Hydraulic system includes HYDRAULIC GEAR PUMP, control valve, lift arm, hydraulic block, and all pipes (HST, front, rear, PS). Every item has a reference number, part number, quantity, and serial number range. That’s the difference between a dealer catalog and a third-party list.

Why OEM Parts Catalog Beats Aftermarket Lookup

I’ve used too many aftermarket parts lists that show the wrong image or skip obscure parts like the HST oil cooler or the bi-speed turn shift fork. This Kubota factory document – 304 pages – came straight from the printer. No one reinterpreted the drawings or cleaned up the part numbers. The column headings are exactly what Kubota used: Ref.No, Part No., Description, Q’ty, S.No. (serial number range), I/C (interchangeability). The instructions at the front explain how to read the serial number codes, including the arrow directions for new-old interchange. If you work on multiple units, the Automotive Industry Overview on Wikipedia also notes how standardized parts cataloging reduces misorders – but this manual does the job for your B1750HST-D.

FAQ – Kubota B1750HST-D Parts Catalog

Does this manual include exploded diagrams for the cylinder head?

Yes. Section 01T006 (CYLINDER HEAD) and 01T007 (VALVE/ROCKER ARM) both have exploded views with callouts.

What is the difference between a parts catalog and a service manual?

A service manual tells you how to take it apart and put it back together, with torque specs and procedures. A parts catalog shows you the exact part numbers and quantities for every bolt, gasket, and seal. You need the service manual to do the work, but you need the parts catalog to order the correct parts. This catalog is 304 pages of exploded diagrams and part numbers only – no repair instructions. It replaces the binder that Kubota dealers used for parts ordering.

Can I use this to find the correct part number for my B1750HST-D’s fuel injection pump?

Absolutely. Open to the INJECTION PUMP section (01T021) and its component parts (01T022). You’ll see the pump body, plungers, delivery valves, and seals. Match your serial number range against the S.No. column to get the right update level.

How do I interpret the country codes in the parts book?

The introductory pages explain: A=USA, CA=Canada, FR=France, etc. If the Remarks column shows EXCEPT [FR], that part works everywhere except France. If it shows [A] [AU] [NZ] in the heading, it’s specific to those markets. Read the instructions on page 1 before ordering anything.

This catalog doesn’t teach you how to turn a wrench. What it does is hand you the exact Kubota part number for every component in the engine, fuel system, drivetrain, hydraulics, steering, and body. No more guessing, no more returns. Access the Factory Manual and keep it on your tablet or print the pages you need. You’ll save the cost in one correct order.
