Scania 6506120 2007 Parts Catalog – OEM Part Numbers for Cylinder Head & Rocker Cover

You need a valve guide for a Scania cylinder head. The aftermarket catalog gives you four rows of numbers and a note that says “verify fitment.” That’s a waste of time. This is the Scania 6506120 2007 Parts Catalog – 168 pages of factory-sourced part numbers, exploded diagrams, and Scania’s own reference numbers. No guesswork. You get the part number, the remark, and the exact position on the drawing. If you’re rebuilding a cylinder head on a Scania engine number 6506120, this is the only document you should trust.

Cylinder Head: Exploded Diagrams and Part Numbers

The OCR sample shows exactly how Scania lays out the cylinder head assembly. Page 1 through page 3 give you the full exploded view with 36 position numbers, each tied to a specific Scania part number. Examples: 1521220 for a cylinder head, 1385383 for intake valves, 1728922 for valve springs. You also get the remark column that tells you quantity and application – like “exhaust” or “intake.” No interpretation needed.

Why Do You Need the 2007 Scania Parts Catalog?

Aftermarket part lists often renumber or consolidate Scania’s original references. You end up ordering a valve stem cap that doesn’t fit because the aftermarket list omitted the “K” suffix that indicates a hardened version. This catalog uses Scania’s own numbering system from 2007 – the same system still used for superseded parts today. You can match it directly to your existing engine parts and avoid returns.

168 Pages of Factory-Sourced Data

That page count covers the engine number 6506120 from front to back. The catalog includes the cylinder head section (01-01-0156), the rocker cover assembly (01-01-0631), and all related fasteners and gaskets. Torque values are not in this catalog – this is a parts document, not a service manual – but the exploded diagrams let you see exactly how each part fits, including the screw lengths (e.g., M16x228 for position 15). You still need the Scania service manual for assembly torque specs, but this catalog tells you which part to order.

Rocker Cover Assembly: Exact Part Numbers

The rocker cover section (pages 4–5) shows the cover, gasket, flange screws, filler cap, and the instruction plate. Part numbers like 170699 for the rocker cover and 320745 for the gasket are listed with cross-references to chassis types (DC14 57/64A, DI14 81A, etc.). If your Scania has a different engine letter code, the part may still be the same – the catalog tells you that in the remark field.

Check the Source: OEM Scania

This is a direct PDF from Scania CV, dated 03/05/2007. The watermark and copyright are present on every page. There are no aftermarket reprints or generic drawings – each exploded view is Scania’s engineering drawing. If you are sourcing parts for a fleet of Scania trucks or an industrial engine, having the factory catalog means you can verify part numbers before you call the dealer. For a broader look at Scania’s engine line, the Automotive Industry Overview provides context, and you can reference the Internal Combustion Engine article for basic engine concepts.

Frequently Asked Questions

Can I use this catalog for a Scania engine number different from 6506120?

No, it is specific to engine number 6506120.

Does this catalog include torque specs for cylinder head bolts?

No, it is a parts catalog, not a service manual. Torque specifications are found in the Scania service manual for that engine. However, the parts catalog lists every bolt and washer by part number (e.g., position 28: M16x160 screw, position 29: washer 4 mm thick). If you need to know the correct bolt length or grade, this catalog gives you the exact Scania part number to order – but you must get the tightening procedure from the factory service documentation. Using the wrong torque on a Scania cylinder head can cause head gasket failure or bolt stretch, so never guess.
