Shibaura SG280E 2011 Parts Catalog

Every time a part number doesn’t match, you lose an hour. A wrong gasket, a misidentified bearing, a seal that’s off by a millimeter – that’s a trip back to the counter and a machine sitting dead. This Shibaura SG280E 2011 Parts Catalog puts the factory’s own numbering system in your hands. 68 pages of Japanese and English text, with exploded illustrations and a key number system that ties each part directly to its illustration. I’ve ordered parts off aftermarket catalogs that showed the wrong bolt length for a hydraulic pump bracket – that doesn’t happen when you’re reading the same document the Shibaura parts counter uses.

If you’re maintaining an SG280E slope mower, you need the exact part number for every fastener, seal, filter, and structural component. This catalog covers the complete machine: chassis, engine group (N843-D-SG280), hydraulic system, and frame. The PDF scans clean, and the index at the front explains every column – Key No., Parts No., Name, Quantity, Interchangeability, Application Model, Size, and Remarks. That interchangeability column is where aftermarket reprints usually drop the ball; this manual keeps the original asterisks, A/B/C/D/E/F codes that tell you if an old part can be swapped for a new one or if you’re locked into a specific serial range.

Understanding the Parts List Format

Page 2 and 3 of the catalog lay out exactly how to read the list. Each illustration has reference numbers (Key No.) that match the table. The table gives you the 8-digit Shibaura part number, the English and Japanese name, the quantity used per assembly, and a compatibility symbol. The asterisk (*) means the part is no longer supplied – that saves you from ordering something that doesn’t exist. The letter “A” indicates full interchangeability between old and new parts. “B” means only the new part fits both old and new machines. “D” means no interchange – you must order the part for your specific serial number. I’ve seen techs waste a whole afternoon because they didn’t check the “D” symbol and got a part that wouldn’t bolt up.

Interchangeability Symbols: What Those Asterisks Mean

Five symbols control your buying decisions in this catalog. The asterisk (*) tells you not to order – supply discontinued. “A” says old and new parts swap freely. “B” limits you to the new part only on both old and new assemblies. “D” is a hard stop – new part only on new machines, old only on old. “E” marks an added part for a specific serial number range. “F” means a part is obsolete and the stock is all that’s left. A blank field means the part is current and universal. You need to check the “Applicable No.” column next to the symbol; it gives the engine or chassis serial number where the design changed. Without that, you could order an oil pan that doesn’t fit your SG280E because yours was built after the revision.

68 Pages of Factory Part Numbers

The entire document is 68 numbered pages, starting with how to read the list, then moving into each major assembly. The engine group includes the N843-D-SG280 diesel power unit. The chassis and body sections show every bolt, bracket, and panel. The hydraulic system parts are listed with their o-ring sizes and thread pitches. This is not a service manual; it’s a parts book. But paired with a Shibaura SG280E Slope Mower Workshop Manual, you get both the repair procedure and the exact replacement number. I keep both on the tablet in my toolbox so when a customer asks “how long to get that part?” I can read them the number off the screen and they can order it before I even finish the diagnosis.

Who Needs This Parts Catalog

If you own an SG280E slope mower and do your own maintenance, this catalog keeps you from playing the part-number guessing game with the dealer over the phone. If you run a repair shop that sees these machines, having the OEM numbers on hand means you can quote the job accurately and not eat the cost of a returned wrong part. Beginners who are intimidated by parts diagrams will find the key-number system straightforward – the illustration has a number, the table has the same number, and you read across. No interpretation required. The catalog is bilingual (English and Japanese), but the English headers are clear enough for any North American mechanic.

Source Validity: OEM vs Aftermarket

What you get from AutoRepairManuals is a direct scan of the original 2011 Shibaura publication. The document bears the IHI Shibaura Machinery Corporation branding, the part number format is the factory’s own, and the interchangeability codes are exactly as they appear in the Japanese parts master. Aftermarket catalogs that recompile part numbers often drop the interchangeability column, or they update part numbers without noting the old-to-new cross. That leads to ordering a part that is physically different and won’t fit. If you want to understand the diesel engine family this mower uses, this Wikipedia article on diesel engines gives you the background on the N843 architecture. For the broader automotive parts landscape, Automotive Industry Overview offers context. But for the specific numbers that let you buy the correct part right now, you need this factory catalog.

FAQ

Does this catalog cover engine internal parts for the N843-D-SG280?

Yes, the engine group section lists pistons, rings, bearings, gaskets, and seals with factory part numbers.

How do I interpret the interchangeability codes like “A” or “D” in the parts list?

The codes are explained on page 3 of the catalog. “A” means the new part and the old part are interchangeable on both old and new machines; you can use either. “B” means the new part can be used on old machines, but the old part cannot be used on new machines. “D” means there is no interchangeability – the new part fits only new machines and the old part only old machines. Each code is paired with an “Applicable No.” column that gives the serial number where the design change took place. Always verify your machine’s serial number before ordering a part marked with any code other than blank. Failure to do so can result in a part that physically won’t install, leading to returns and downtime. The catalog also uses “*” for discontinued parts, “E” for added parts at a specific serial, and “F” for obsolete parts available only while stock lasts. If you see a code without a clear serial reference, cross-check with the Shibaura dealer using your engine number (EN- prefix) or chassis number.
