YMZ ЯМЗ-236ДК, ЯМЗ-238АК 2002 Parts Catalog

I’ve been in this trade long enough to know that ordering the wrong part because you trusted a third-party parts listing costs money and kills time. This is the factory Parts Catalog for the YMZ ЯМЗ-236ДК and YMZ ЯМЗ-238АК diesel engines, printed in 2002. It’s 108 pages of nothing but the real deal – part numbers, coatings, and interchange codes that the OEM stamped on the drawing. If you need a specific bolt, gasket, or injector line for a Don-1500B combine or a T-11.01 tractor, this is where you start. Skip the generic databases.

What the Catalog Covers: Parts and Units

This catalog lists every assembled unit and piece part for the ЯМЗ-236ДК and ЯМЗ-238АК engines except welded assemblies. Each group has an exploded-view drawing with numbered callouts, and the part list follows those numbers in ascending order. Page 2 shows the master catalog number 238АК-3902020. Page 3 explains how to read the part suffixes – letters like A, A1, A2 indicate interchangeability; letters like B, V, G indicate non-interchangeability. That’s the kind of detail that stops you from ordering a piston that won’t fit. Fastener numbers include a hyphen and a coating code – for example, П2 means phosphate and oil, П29 is zinc-plated. You need that info when corrosion resistance matters.

Part Numbering Explained

Numbers in bold type in the catalog are the recommended spare parts list – the stuff the factory actually stocks. Six-digit fastener numbers get a coating suffix (П, П2, П5, П15, П29, П29С, П34). If you’re rebuilding a combine engine that sits outside all winter, you want П29 or П29С coating on those head bolts. The catalog tells you exactly what was installed. No guesswork. The YMZ 650.10 2009 Parts Catalog and YMZ 238Б/238Д 2002 Parts Catalog use the same numbering system – once you learn this format, you can move across YMZ models.

Source Authenticity: OEM vs. Aftermarket

Aftermarket parts catalogs often re-draw the illustrations and skip coating codes. This is a direct scan of the original Avtodiesel (YMZ) document. Every page carries the factory part number and the “ОАО Автодизель (ЯМЗ)” stamp. When you call YMZ or their trade representative with a part number from this catalog, they’ll recognize it. I’ve had too many jobs held up by a reprint that left off a digit. Buy the OEM print.

Which Engines and Equipment Fit?

ЯМЗ-236ДК (base version) goes on the Don-1200B combine. Variants like -2 and -5 go on Yenisey-1200 and Kedr combines. ЯМЗ-236ДК-7 is on the T-11.01 tractor from Cheboksary. ЯМЗ-238АК goes on Don-1500B; -2 on SKR-7 Kuban; -4 on KES-9-1 Slavutich. The catalog covers all those variants. If your machine matches one of those, you have the right manual. The Massey-Harris-Ferguson FF 30 GS 1957 Parts Catalog | OEM Fastener Guide is a different animal – this is strictly for Soviet-era diesels.

Using the Catalog on the Bench

Open to page 3 – the preface gives you the engine serial number location (on a plate attached to the cylinder block). Write down your engine number before you flip to a group page. Each unit is illustrated; find your part on the drawing, note the position number, then read the part number from the list. The coating code is right there. Order that part, not the one that looks similar. If you’re outside Russia, contact the Avtodiesel trade office at the address in the catalog (150040, Yaroslavl, October Ave. 75) or their international reps. For a broad technical background on these engines, see this Wikipedia article on diesel engines – but for parts, nothing beats the factory catalog.

Frequently Asked Questions

Can I use this catalog to find torque specifications for my YMZ engine?

No. This is a parts catalog, not a service manual. Torque specs are not listed.

What does the part number suffix like П2 or П29 mean?

Those are anti-corrosion coating codes per the factory standard. П2 is phosphate and oil, П29 is zinc-plating with passivation, П34 is passivation only. The catalog lists them for every fastener. When you order a bolt, include the coating code or you may get a plain steel part that rusts. The suffix is part of the full part number – leave it off and the dealer will ship the wrong item.

Is this manual available in English?

The catalog is bilingual. Each heading and the preface appear in both Russian and English. All part numbers are numeric, so language isn’t a barrier.

How do I identify which engine variant I have?

Locate the engine identification plate on the cylinder block. It shows the model (e.g., ЯМЗ-236ДК-2) and build date. Match that to the variant list in the catalog’s preface (page 3). The catalog covers all listed variants of both ЯМЗ-236ДК and ЯМЗ-238АК.

You need this catalog if you work on YMZ engines used in agricultural and construction equipment. Access the Factory Manual from AutoRepairManuals and keep it on your laptop or print it for the shop. Every part number is genuine OEM. You won’t waste time cross-checking against aftermarket lists.
