MWM D 226-6 1981 Parts Catalog – Stop Guessing Part Numbers

Hand you a random bolt and ask you to match it to a diesel engine built in Mannheim. That is what using an aftermarket parts list feels like. The MWM D 226-6 1981 Parts Catalog is the 133-page factory document that kills the guesswork. Every diagram, every part number, every revision comes straight from Motoren-Werke Mannheim AG, not from some third-party re-write. If you need a spur wheel for the camshaft or a gasket set for the crankcase, this catalog is your only shot at getting the right piece the first time.

What’s Inside This Parts Catalog?

Page 1 kicks off with the nameplate data and the part-number format. Page 3 lays out the ordering procedure – five fields you must fill: engine type, engine number, quantity, part number plus diagram reference, and dispatch preference. The rest of the 133 pages are grouped into diagram tables (Tafelverzeichnis) that show every serviceable part as an exploded drawing with an item number and the corresponding part number. You get the official MWM part code, not a cross-reference that might be swapped at the factory. For a D 226-6 that has been sitting in a generator or irrigation pump, this catalog tells you exactly what was installed in 1981.

Engine Identification – Nameplate Data

Before you order a single piece, pull the nameplate off the engine. The catalog shows you exactly where to read the motor type (D 226-6) and the engine number (e.g., 226.62.01000). Those two numbers are checked against the diagrams. If you skip that step, you might end up with a gear that has the wrong tooth count or a cylinder head gasket that doesn’t match the block revision. The introduction on page 2 even prints a blank nameplate layout so you know what you are looking for. No translation needed – the field labels are in German, English, French, Italian, and Spanish.

Ordering Parts: The Factory Procedure

Page 3 gives you a telegraph example: “Express send a 17-6010A/9 Engine No. 226.62.01000”. The catalog expects you to reference the diagram number (17-6010A) and the item number (9) from the drawing. That means you need the catalog open on your bench, not a scanned page you printed five years ago. The parts list itself is grouped by major assembly: cylinder head, crankcase, fuel system, cooling, etc. Each diagram has a table with columns for item number, part number, description, and quantity per engine. Do not assume you can get away with a generic “fuel injection pump” – the catalog lists the specific MWM code for your D 226-6 version.

Diagram Tables and Part Numbers

The diagrams are black-and-white line drawings with callouts. The part numbers follow a 12-digit MWM format (e.g., 6.325.0.371.007.4 for the camshaft spur wheel). Each drawing is labeled with the diagram number and the edition letter (C-Ausführung, 3. Auflage). The catalog also contains a list of tables at the front so you can jump directly to the assembly you need. For a home garage machanic or a small shop rebuilding a D 226-6, this is the only reliable source for those numbers – no aftermarket parts catalog renumbers them correctly.

3 Reasons to Use OEM Documentation

First, aftermarket parts lists often skip the revision letter. That C-Ausführung (3rd edition) matters because MWM changed the fuel injection pump mounting in later revisions. Second, the catalog includes the engine number prefix range – if your engine number is 226.62.01000, that tells you which diagram edition applies. Third, the factory ordering example shows you exactly how to avoid delays: specify the diagram and item number, not just the part name. Do that once, and the parts arrive in days, not weeks.

This catalog is all you need to order correct parts for your D 226-6, but if you need the operation and maintenance procedures, check the MWM Sprint 2008 User Manual – OEM Operation & Maintenance.

How many pages does this manual have?

133 pages.

Does this manual cover the D 226-6 engine?

Yes, it is specific to the MWM D 226-6 model. The catalog title and all diagrams reference the D 226-6 directly. If you have a different variant (e.g., D 226-4), the diagrams and part numbers will differ.

Can I use this to repair my engine?

This is a parts catalog, not a repair manual. It contains exploded diagrams and part numbers for ordering spares. It does not include torque specs, disassembly procedures, or service intervals. For repair instructions you would need the factory workshop manual. However, owning the parts catalog is essential for any rebuild because you must know the exact part number before you start the repair – ordering the wrong piston or gasket will stall the job.

Is the manual in English?

The manual is multilingual: German, English, French, Italian, and Spanish. The parts tables and diagrams use part numbers that are language-independent, so any mechanic can read the drawings.

That’s the facts. If you work on an MWM D 226-6 – whether it is a generator, a pump, or a marine engine – you need this catalog open next to your toolbox. The 133 pages of factory diagrams and part numbers will save you calls to the dealer and the time spent cross-referencing wrong parts. Order it now. Access the Factory Manual.
