Shibaura S328, S33H 1997 Parts Catalog

If you are rebuilding a Shibaura S328 or S33H tractor and you order the wrong part because you guessed at the number, you are wasting time and money. I have seen more than one engine rebuild sit on a shelf for two weeks waiting for the correct piston ring set because someone matched a cross‑reference from a non‑OEM site. This Parts Catalog is the factory document that tells you exactly which part number fits which serial number range. No guesswork, no aftermarket interpretation. It is the same binder the dealer parts counter pulls from when you ask for a water pump. this Wikipedia article on diesel engines explains the basic theory, but this catalog gives you the factory code system that lets you order the right piece the first time.

How to Read the Parts List: Codes and Compatibility

Page 2 of the catalog shows the format. Each model variant (S328-4-NL-A, S328-4-FR-B, S33H-SZ-C, etc.) is listed with its code – a five‑ or six‑digit number that identifies the exact configuration. The engine type, slide, HST, PTO, tire size, and hydraulic system are all encoded. If you are ordering parts for a 1997 S33H with a 13.6‑16 draft control tire, you need the correct code to get the right bracket or linkage. The catalog also explains compatibility symbols on page 3: a mark for supply not available, A for full interchangeability, B for new part only fits older chassis, D for no compatibility, E for obsolete parts. Do not skip this section. I have seen a tech install a clutch disc that was marked B onto an older flywheel – it did not work and cost two hours of labor to reverse.

Engine and Chassis Parts Coverage

The catalog covers the complete tractor: engine standard parts controlled by engine serial number (EN), chassis and body parts controlled by unit serial number. The table on page 2 lists all code indications for the S328 and S33H, including the four‑wheel‑drive variants. It includes the J843-2-S328-01 engine and the N843-2-S33H engine. The parts list is organized by illustration with a reference number that links to the part number, name, quantity, and application notes. You will find things like cylinder head gaskets, hydraulic pump seals, and PTO shaft components. This is not a service manual – there are no torque specs or repair procedures – but without the correct part numbers, your repair job stops cold. If you need the service manual for the S328, check the Shibaura SX21 SX24 Parts Catalog | OEM Part Numbers for smaller models.

How to Order Parts Correctly

Page 3 has a section titled “ご注文について” (How to Order). When you call a dealer, you need the part number, part name, and quantity. The catalog states that interchangeability parts are generally not recommended unless a mistake has been made – meaning do not substitute OEM parts unless the factory says it is okay. Always use SHIBAURA genuine parts. Aftermarket copies cause early failure and poor performance. The parts list code number is 300830679; have that ready when ordering. The catalog also notes that prices are in a separate price list, so do not expect to find dollar amounts here.

Why OEM Part Numbers Matter – Not Aftermarket Copies

I have seen aftermarket belts that are 1/8″ too short and hydro filters that bypass because the thread pitch was wrong. This Parts Catalog is from Ishikawajima‑Shibaura Machinery Co., Ltd., printed September 1997. It is 108 pages of verified factory data, not a third‑party compilation. The compatibility symbols and code system are specific to Shibaura tractors. If you use a generic parts lookup, you risk getting a part that fits the same engine family but not your specific chassis code. For the S33H, there are eight different variant codes; each may use a different hydraulic line or clutch fork. The catalog lists them. You can also pair this with the Shibaura ST440, ST445 2003 Parts Catalog – OEM Factory Part Numbers if you work on later models.

Using the Code Indication System

Page 2 of the catalog shows a table of model codes with columns for engine, slide, HST, PTO, tire size, and hydraulic system. For example, the S328-4-NL-A has code 341600 and the S33H-SZ-A has code 347801. When you look up a part, the illustration list tells you which code applies. The symbols and abbreviations (ASSY, AR, LH, RH, STD) are explained on page 3. Do not ignore the “Manufacture No.” fields – that is how you verify if a part number supersedes an older one. If you are working on a tractor with a missing serial number plate, cross‑reference the engine number and chassis casting codes to narrow down the variant.

Audience and Real‑World Use Case

This catalog is for anyone who owns a Shibaura S328 or S33H tractor – whether you are a home garage enthusiast restoring a classic compact tractor or a small farm owner keeping an old workhorse running. I have had customers try to order a steering cylinder seal using only the model name and got the wrong bore size. With this catalog, you can find the exact part number for the seal kit. It also helps if you are buying a used tractor and need to verify that all parts are original. The Shibaura ST329, ST333 2002 Parts Catalog – OEM Factory Specs covers similar models with different production years.

Source Authenticity: Original Factory, Not a Reprint

This is a digital scan of the original September 1997 factory print from Ishikawajima‑Shibaura Machinery Co., Ltd., control number ISP 3008. It is not a third‑party reprint. The Japanese and English text, the hand‑drawn illustrations, and the logo are intact. The PDF is 108 pages, searchable, and includes the original code table and compatibility symbols. No information has been added or removed. This is the document that the dealer used when ordering parts for these tractors. You should trust it over any cross‑reference website.

Does this catalog cover the S33H model?

Yes.

What does the compatibility symbol ‘A’ mean?

Symbol ‘A’ means both old and new parts are fully interchangeable. You can install the new part on an older chassis or use the old part on a newer chassis. This is the safest compatibility rating. Other symbols (B, D, E) have different restrictions, all explained on page 3 of the catalog.
