Mitsubishi SS-SERIES 2007 Service Manual – Factory Diesel Engine Specs

Mitsubishi SS-SERIES 2007 Service Manual – I’ve been turning wrenches for 28 years, ASE Master since ’98, and I can tell you right now: if you’re working on one of these Mitsubishi SS-SERIES diesels without the factory book, you’re guessing. And guessing on a fuel injection pump or head torque costs you parts and time. This is a real OEM Service Manual – 84 pages of what Mitsubishi Heavy Industries put together for their SS-SERIES engines. Not a reprint, not a third-party interpretation. The original 2007 publication.

Before you touch a wrench, you need the safe procedures. Chapter 1 covers Basic Safety Precautions – fire, explosion, exhaust poisoning, battery handling, lockout/tagout. It tells you exactly what type of explosion-proof lighting to use and how to prevent electrical shorts. That’s not fluff; that’s the difference between walking out at the end of the day and being carried out.

What’s Inside: 84 Pages of Factory Procedures

Every page is a direct scan of the original Mitsubishi binder. The foreword lays out the limited warranty and emission warranty (including EPA compliance for US-sold engines). The table of contents lists all chapters: 1 Safety, 2 Names of Parts, 3 Operation, plus periodic inspection and maintenance sections. You get the full index of illustrations and tables. Page 3 tells you: “Never operate the engine or conduct maintenance without completely understanding this manual.” That’s the standard we hold to in my shop.

Engine External Diagrams and Part Names

Chapter 2 is where you’ll spend a lot of time. It covers external diagrams for the S4S, S4S-DT, S6S, and S6S-DT engines – both in-line and distributor-type fuel injection pump variants. Each left and right view is labeled. Need to identify the stop solenoid type? It shows RUN OFF (ETS) and RUN ON (ETR) configurations. The equipment section includes the preheat indicator, water temperature meter, ammeter, hour meter, and engine protection devices like oil pressure switch and thermo switch. If you’re swapping parts or troubleshooting a no-start, this chapter saves hours.

Fuel System: In-Line vs Distributor Injection Pumps

The manual covers both fuel system types explicitly. For the S4S and S6S families, you’ll find separate diagrams for in-line and distributor pumps. That matters because the timing procedure and pump removal steps differ. The factory spec for fuel system components – pipe connections, injection nozzle pressures – are all in here. No aftermarket manual gives you the same precision. The emissions warranty section even lists warranted parts related to the fuel system.

Safety Precautions: Factory’s Own Warnings

Read Chapter 1 end to end before you start. It covers: keep flames away from fuel, use explosion-proof lighting, prevent wire short-circuits, lockout/tagout rotating parts, never open the radiator cap when hot, proper disposal of waste oil and coolant, and handling of long-life coolant (LLC). It also warns against modifying the engine or breaking seals. One line I’ve seen ignored: “Do not operate the starter for a prolonged time.” That kills starter motors and batteries. The manual tells you the correct procedure.

Does This Manual Cover the Fuel System?

Yes, and in detail. The fuel system appears throughout: in the parts diagrams, the operation chapter (preparations include inspecting fuel lines), and the periodic inspection sections. If you need to bleed air from a distributor pump on an S4S-DT, this manual gives you the correct sequence. No guessing.

Source Authenticity: OEM vs Aftermarket

I’ve bought aftermarket manuals that claim to cover “SS-SERIES” but they mix up diagrams from other models. This one is the genuine Mitsubishi publication with Pub. No. 99610-29110. The pages are scanned from the original Japanese print – no reprints, no copy-paste errors. The warning statements use the exact formatting Mitsubishi requires. That matters when you’re torquing head bolts or setting injection timing. If you want to see what a real factory manual looks like, compare it to the aftermarket junk on eBay.

Does this manual cover the S4S-DT turbo diesel engine variant?

Yes. The manual includes left and right external diagrams for the S4S-DT with both in-line and distributor fuel injection pumps. It also covers the turbocharged variant in chapter 2 names of parts.

How is this factory manual different from a generic aftermarket manual?

Aftermarket manuals often omit safety warnings, use generic diagrams that don’t match your specific engine configuration, and lack OEM torque specs. This Mitsubishi SS-SERIES service manual includes the exact part numbers, wiring colors, injection pump timing data, and factory-required lockout/tagout procedures. The emission warranty section (page 5) lists EPA-warranted components. No generic reprint can reproduce the original Mitsubishi engineering data because they don’t have access to the source. I’ve seen techs strip bolt threads using aftermarket torque values that were off by 15%. That doesn’t happen with the real factory manual.

If you’re serious about doing the job right and not wasting time hunting for specs, get the actual factory documentation. Years of experience have taught me that the factory book pays for itself on the first major repair.
