Mitsubishi S4L2, V363JG 2008 Parts Catalog

You’ve got a Mitsubishi S4L2 or V363JG diesel sitting on the stand and you need parts. I’ve seen too many guys order the wrong crankcase because they trusted a third-party list. This is the factory Mitsubishi S4L2, V363JG 2008 Parts Catalog – 114 pages, published August 2008, straight from Mitsubishi Heavy Industries. No reprints, no guesswork. If you want to know exactly which dowel pin or shim goes where, this is the document you pull off the shelf.

Before I get into what’s inside, let me be clear about the difference between a parts catalog and a service manual. This book does not tell you how to rebuild the engine or give you torque specs. It gives you part numbers, assembly diagrams, and the exact way Mitsubishi organized their genuine parts. You still need the Mitsubishi S-Series Diesel Engines 2001 Service Manual for the repair procedures. But if you order a part without this catalog, you’re flipping a coin.

Engine Number Identification: S4L2-V363JG

Page 3 of this catalog gives you the exact cross-reference. The engine name is S4L2, the model is V363JGH (for generator application), and the applicable serial number starts at 157087-UP. That’s the break point. If your engine serial is below that, this catalog may not apply. Check your serial plate before you order anything. The catalog also notes that some illustrations may differ from actual parts – that’s listed right in the guide section. Don’t assume a picture is exact.

Genuine Parts vs. Imitation: What the Manual Says

Page 2 has a direct paragraph titled “Mitsubishi Genuine Parts.” It says imitation parts are not reliable from the viewpoint of material and manufacturing method. I’ve personally seen cheap aftermarket main bearing caps crack under load. This catalog lists part numbers for items like the crankcase assembly (32507-70010) and the cap main bearing (32507-02700 N1). When you order genuine, you’re following the same QC system that Mitsubishi used when the engine was built. Mitsubishi S4L2 Engine Parts Catalog is the only source for those specific numbers – aftermarket databases often swap supersessions without telling you.

Using the Parts Catalog: Group Numbers and Ref Numbers

Flip to the sample page on page 4. The catalog uses group numbers like 01-01 for crankcase. Each part has a reference number, a 10-digit part number, a description with codes like B/W (bolt with washer), and quantity per engine. The column for model and quantity shows S4L2 with specific counts. Pay attention to the “Applicable Serial No.” column – some parts only apply after a certain engine number. For example, the crankcase hanger pin 011286-UP. You order the wrong one and it won’t fit.

Where to Find Torque Specs? They Aren’t Here

I said it once, I’ll say it again – this is a parts catalog, not a repair manual. You won’t find torque values or clearance specs. But what you will find is the numerical index starting at page C1 and the standard bolt/washer listing on page D1. That bolt listing gives you part numbers for individual bolts and washers. If you need torque data, you need the Mitsubishi L3E V363JG Diesel Engine Parts Catalogue for your specific model, or the service manual.

7 Key Sections You Need to Know

The catalog is organized with these major groups:

• Crankcase assembly (group 01)
• Cylinder head, valve, and rocker arm
• Fuel injection pump and governor
• Lubrication system
• Cooling system
• Starting motor and alternator
• Standard parts (bolts, washers, seals)

Each group has exploded diagrams and a parts list. The diagram on page 4 shows the crankcase with reference numbers. You work left to right: find the ref number, read the part number, verify the quantity. For high-demand parts (marked with a dot), order spares. Mitsubishi even includes a note that part numbers are subject to change without notice – so always double-check with your dealer if the engine has been updated.

Does This Catalog Cover Every Engine Mod?

Only S4L2 with V363JGH generator spec and serial 157087-UP. If you have a different application (like a marine or industrial version), this catalog may not apply. The Automotive Industry Overview on general engine parts can give you context, but for part numbers, you need the exact match. I’ve seen guys use a catalog from a similar engine and end up with a piston that’s 0.5mm too tall.

FAQ

Does this catalog include full engine assembly diagrams?

Yes. Each major assembly like crankcase, cylinder head, and fuel system has an exploded diagram with reference numbers and part numbers. Not every single bracket or hose is shown, but the core components are covered.

Can I use this to order parts for a non-generator S4L2?

No. This catalog specifies model V363JGH for generator use. Other models like V363JGR (different spec) have different part numbers. Check your engine nameplate.

Do the part numbers match current Mitsubishi inventory?

Mostly. Mitsubishi publishes supersession lists. Your dealer can cross-reference. The catalog is original from 2008, so some numbers may have been replaced. The numerical index at the back helps locate supersessions.

Is this a scanned PDF or a reprint?

Original OEM digital scan from the factory publication. 114 pages, clear diagrams, searchable text. No aftermarket interpretation, no formatting changes. What you see is what Mitsubishi printed in 2008.

If you’re working on an S4L2 or V363JG and you need to identify which crankshaft bearing cap or fuel injection line to order, this catalog will save you a return trip to the parts counter. I keep a copy in my shop tablet for when customers bring in generator sets from the oil fields. Access the Factory Manual from AutoRepairManuals and you’ll have the exact part numbers Mitsubishi expects you to use. For more context on engine industry standards, check the Automotive Battery article – just kidding, but do take a look at our other OEM catalogs if you work on multiple engines. This one is specific, it’s factory, and it’s the only one I trust.
