Mitsubishi S4L2 2006 Parts Catalog – Factory Part Numbers for the S4L2 Diesel

I’ve seen too many guys pull a cylinder head off a Mitsubishi S4L2 and then spend two days hunting down the right valve guide because they trusted an aftermarket cross-reference. That’s wasted time. You need the factory breakdown. This Mitsubishi S4L2 2006 Parts Catalog – 58 pages – gives you exactly what Mitsubishi stamped on the part. No guesswork, no translation errors. Read on.

Cylinder Head Group (01.01): What You’ll Find

Page 1 of this Parts Catalog opens with the Zylinderkopf (cylinder head) group for the S4L2-61KL-HR16 engine. You get part numbers for the head itself (5527662487), sealing caps (5527662488, 5527662266), valve guides for exhaust and inlet (5527662489, 5527662490), the combustion jet (5527662421), taper plug (5527662072), head bolt (5527662493), head gasket (5527658979), engine hanger (5527662494), and bolt with washer (5527662248). Every single one has a factory drawing number and sheet reference – you won’t wonder if the part fits. If you need a valve guide, order 5527662490. Period.

Valve Train Group (01.02): Inlet, Exhaust, Springs, Locks

Page 3 covers the Ventiltrieb (valve train). Here you find inlet valves (5527658981), exhaust valves (5527658980), valve spring (5527662495), retainer (5527662360), valve lock (5527662379), valve stem seal (5527662005), valve cap (5527662496), and the complete rocker & shaft assembly (5527662497). Also listed: bearing (5527662506), washer (5527662507), key (5527662372), and a bolt with washer (5527662236). Each part gets its own group, drawing number, and sheet – no confusion between inlet and exhaust guides.

Why an OEM Parts Catalog Beats Aftermarket Cross-References

Aftermarket catalogs often merge part numbers or skip the “drawing no.” column. Mitsubishi prints the exact Ident no. next to the German, English, and French description. If a parts house tells you a different number, you go back to this catalog and check. That saves returns and downtime. I’ve had a guy install a wrong valve spring because his generic book listed one spring for three engines. This catalog shows the spring part number for the S4L2 specifically. Use it.

58 Pages of Factory Diagrams – Not Reprints

2006 print date on the header – that’s the year Mitsubishi released this Parts Catalog. 58 pages cover the engine groups. Page 1 gives you the exploded diagram reference for the cylinder head group. Page 3 does the same for valve train. You see the group number (01.01, 01.02), drawing number, sheet number, and the three-language label. No aftermarket reprint, no faded scans. This is the original PDF from Mitsubishi.

Related Manuals That Work With This Parts Catalog

To fully rebuild the S4L2, you’ll also want the service manual for torque specs and assembly sequence. Check out the Mitsubishi S-Series Diesel Engines 2001 Service Manual for tightening procedures. For a later version of the engine, get the Mitsubishi S4L2, V363JG 2008 Parts Catalog – OEM Factory Specs. If you work on the smaller S3L2, grab the Mitsubishi S3L2 2009 Parts Catalog – OEM Factory Specs.

For background on diesel engine parts numbering, see the Automotive Industry Overview and Automotive Battery sections – but honestly, the manual itself tells you everything you need.

Does This Catalog Cover Engine Disassembly or Reassembly?

No. This is purely a parts listing – group numbers, part numbers, quantities. You won’t find torque values or step-by-step instructions. You use it to order the right part before you tear down the engine. For assembly, get the matching service manual. But never order parts without confirming the Ident number here first.

Frequently Asked Questions

What does “ZYLINDERKOPF” mean?

Cylinder head. The catalog lists it in German, English, and French. You only need the part number.

Can I use this catalog to find torque specs for head bolts?

No. This is a parts catalog, not a service manual. It tells you the head bolt part number (5527662493) and that it’s a bolt, but not how tight to turn it. You need the service manual, like the Mitsubishi S-Series Diesel Engines 2001 Service Manual linked above, for torque values and tightening sequence. Order the parts from this catalog, then grab the service manual for the work.

How do I decode part numbers like 5527662487?

Mitsubishi part numbers are sequential; the first digits indicate the series. This catalog lists them as “Ident Nr.” and groups them by drawing. Just search the number in any Mitsubishi parts system – it will match exactly. No decoding needed beyond using the catalog as your source of truth.

Is this the same as a service repair manual?

No. It lists only parts, groups, and diagrams. No procedures.
