Shibaura S318, GSB, S320 1993 Parts Catalog – 108 Pages OEM

Description

If you’ve ever ordered a part for a Shibaura S318, GSB, or S320 and gotten the wrong piece because you guessed at the number or relied on some aftermarket cross-reference, you know the frustration. That’s exactly why this 1993 parts catalog exists – to eliminate guesswork. It’s 108 pages of factory-original part numbers, interchangeability codes, and ordering instructions straight from Ishikawajima-Shiura Machinery Co., Ltd.

Parts List Structure: Index Numbers and Key Numbers

Open to any page and you’ll see the same layout – a three-column table with Key Number (図番), Parts Number, and Parts Name, plus columns for application, dimensions, and remarks. The index numbers on the illustration match the numbers in the list. Page 2 explains exactly how to read it: find the index number on the drawing, then look up the corresponding parts number. No flipping back and forth between different sections. The catalog also shows quantity needed per assembly – something aftermarket catalogs skip. For example, the front tire size is 6-12-4PR, rear is 9.5-16-4PR – those dimensions are listed right there in the table.

How to Order Parts Without Getting It Wrong

Read the “How to Order” section on page 3 before you call your supplier. It spells out that you need to provide the part number, name, and quantity. Returns aren’t accepted except for shipping errors, and Shibaura explicitly warns that using non-genuine substitute parts can cause early failure or poor performance. That’s not sales talk – that’s engineering fact. You also need to confirm the engine serial number (EN……) and the chassis number when ordering engine-related parts. The catalog lists the engine models: S318 uses S723-3-S318, S320 uses S753-3-S320. Order the wrong engine part because you ignored the serial number, and you’ll be paying freight both ways.

Interchangeability Codes: What Those Symbols Mean

Page 3 includes a symbol legend that’s worth memorizing. An asterisk (*) means the part is no longer supplied. A circle with a dot (○) indicates the old part number is replaced by a new number shown in the reference column. Letters like A, D, E, F, O code the compatibility between old and new parts. For instance, A means the new part fits all products, but the old part only fits older machines. D means the old part fits old products and the new part fits new products – no swapping. Aftermarket catalogs don’t tell you this. You’ll get a part that looks identical but doesn’t mate with your tractor’s production run. That’s a waste of time and money.

Engine vs Chassis Parts: Which Serial Number Do You Need?

The catalog is divided into two major sections: engine components (controlled by engine serial number) and chassis/body components (controlled by chassis product number). If you need a piston ring, you look up the engine serial number. If you need a steering knuckle, you look up the chassis number. Page 2 states this clearly in both Japanese and English. Beginners tend to grab the first number they see on the tractor plate and order everything off that – wrong approach. This manual forces you to use the correct reference number for each subsystem. That’s the difference between getting a part that fits and getting a paperweight.

108 Pages of Factory Data You Can Trust

This is an OEM publication from December 1993, reprinted with updates through 2007-2008. The control number is ISF 1904, parts list code 182332821. It covers S318, GSB, and S320 models – both the diesel engine and the chassis. Every page is scanned from the original Japanese/English bilingual print. You get the exact same information a Shibaura dealer would have used in the 1990s. There’s no interpretation, no aftermarket editor guessing what “AR” means (it means “As Required” in the abbreviation list). If you’re rebuilding a Shibaura tractor or ordering parts for a customer’s machine, this is the only document that guarantees you’re buying the right component.

Q: Does this parts list include torque specifications?

No. This is a parts catalog, not a service manual. It lists part numbers, names, quantities, and interchangeability codes. Torque values and repair procedures are in the corresponding service manual.

Q: What models are covered exactly?

S318, GSB and S320, GSB. The GSB designation appears to be a series mark. Engine models are S723-3-S318 and S753-3-S320. Verify your tractor’s model plate – the catalog uses those exact designations.

Q: How do I use the interchangeability codes like * ○ A D E F O?

Look at the symbol column next to the part number. A circle means the old part number is superseded by the new number listed in the reference column. A means the new part fits all old and new products. D means the new part only fits new products, and the old part only fits old products – no interchange. E and F are application-specific symbols tied to serial number breaks. The asterisk means that part is discontinued. Always check this code before ordering, or you may receive a part that physically cannot be installed on your machine.

Q: Is this manual in English?

It’s bilingual – Japanese and English. The parts tables have English headings, the how-to sections are in both languages, and the part names are listed in English and Japanese. A non-Japanese reader can navigate it without trouble.

Look, I’ve been turning wrenches since before OBD-II was a thing. I’ve seen guys order an entire head gasket set off a generic number only to find the fire ring is the wrong thickness. This Shibaura parts catalog stops that. You want to rebuild a Shibaura S318 engine or source a steering gear for an S320? Start here. Access the Factory Manual and cross-check every part number against the illustrations. Your wallet – and your customer – will thank you.
