Avtodizel ЯМЗ-236НЕ, ЯМЗ-236НЕ2, ЯМЗ-236БЕ, ЯМЗ-236БЕ2, ЯМЗ-7601.10 2003 Parts Catalog

I’ve seen too many guys order a replacement injection pump for a ЯМЗ-236БЕ only to find the mounting flange is wrong because they used an aftermarket parts list. That mistake costs you a week and the customer’s patience. You need the factory numbers, not a translator’s best guess. This Avtodizel ЯМЗ-236НЕ, ЯМЗ-236НЕ2, ЯМЗ-236БЕ, ЯМЗ-236БЕ2, ЯМЗ-7601.10 2003 Parts Catalog is the exact document Yaroslavsky Motorny Zavod (YMZ) put out for their diesel engines. 194 pages of parts, assemblies, and bolt-on components, all laid out with the original Russian part numbers and corresponding English descriptions.

What This 194-Page Parts Catalog Covers

This isn’t a repair manual—it’s a parts catalog. You get exploded-view drawings for every major assembly group: cylinder block, cylinder head, crankshaft, pistons, connecting rods, fuel system, lubrication, cooling, and timing gears. Each drawing has a table below it listing the part number, quantity per engine, and any coating or interchangeability codes. For example, page 3 explains that bold numbers in the catalog mark the recommended trade nomenclature for spare parts. If you’re rebuilding a ЯМЗ-236НЕ2 that came out of a MAZ truck, you can flip to the right group and verify the exact part number for a connecting rod bearing shell.

Why Use a Factory Parts Catalog Instead of Aftermarket?

Because I’ve had a counter guy hand me a bearing that “fits all 236 models” and watched it spin a rod in under 300 miles. Avtodizel lists six-digit fastener numbers with corrosion-protection suffixes like П2 (phosphating) or П15 (oxidizing). Aftermarket catalogs skip those details. You get the wrong coating, the bolt seizes in the block, and you’re helicoiling at 10 p.m. The factory document includes cross-references for design changes—like the difference between engines with individual cylinder heads (ЯМЗ-236НЕ2, ЯМЗ-236БЕ2, ЯМЗ-7601.10) and those with common heads (ЯМЗ-236НЕ, ЯМЗ-236БЕ). That’s data you won’t find in a generic parts book.

5 Engine Models in One Catalog

This single volume covers five distinct YAMZ power plants: ЯМЗ-236НЕ, ЯМЗ-236НЕ2, ЯМЗ-236БЕ, ЯМЗ-236БЕ2, and ЯМЗ-7601.10. The catalogue draws them as base models and notes configurations that differ slightly from the base—like the 7601.10 with its individual cylinder heads. If you’re maintaining a fleet of Ural trucks or LAZ buses, you’ll find the right group for each engine without juggling five separate PDFs. Each spec sheet is illustrated, and the part numbers follow the same ascending position order shown in the figures.

Read the Coating Codes Before Ordering

Page 3 lists the coating abbreviations used throughout the catalog: П = no coating, П2 = phosphating and oiling, П5 = copper plating, П15 = oxidizing, П29 = zinc plating with passivation, П34 = passivation alone. If your original bolt had a П5 copper plate and you order a zinc-plated substitute, the torque value changes—especially if the bolt goes into an aluminum housing. I’ve seen guys snap a timing cover bolt because they didn’t account for the difference in friction. The catalog flags these codes right on the part numbers, so you can match what came off the engine.

Interchangeability Markings: What A1, A2, or B Mean

Look at any assembly group and you’ll see letters like A, A1, or digits 01, 02 next to some part numbers. Those indicate interchangeable revisions—same form, fit, function. Letters like Б, В, or numbers 10, 20 mean the part is not interchangeable with the earlier version under the same base number. For example, a piston with marking “A2” will swap with the baseline part, but a “Б” marking means you need to check the block machining. The catalog’s preface explains this on page 3. I’ve used it to sort out a mis-boxed set of liners for a ЯМЗ-236БЕ2—saved me a return trip to the dealer.

Frequently Asked Questions

Does this catalog include torque specifications?

No. This is a parts catalog, not a service manual. It lists part numbers and assembly units. For torque values you need the factory repair manual for your specific engine model.

Can I use this catalog to order parts for a ЯМЗ-236НЕ2 that has been swapped into a ZIL 130?

Yes. The catalog covers the base engine configurations, regardless of the chassis. However, you need to check the engine’s serial number plate (located on the cylinder block) to confirm exactly which variant you have—common head vs. individual head—because the cylinder head gasket and related parts differ. The catalog shows both setups.

Are the part numbers still valid for current production?

This edition was compiled as of April 1, 2003. Avtodizel continuously improves their engines, so some numbers may have superseded. The catalog notes that changes will be included in later editions. For the most current parts, contact the factory’s trade representatives directly using the address listed in the preface (page 3). But for 2003-era engines, this catalog is definitive.

How do I find the part number for the injection pump on a ЯМЗ-7601.10?

Look in the fuel system group—the drawings will show the pump assembly with its components. Each item has a position number tied to the table. Find the pump assembly number in the table, then verify the coating code. If the engine uses a different calibration, the catalog may list multiple pump options with different A/B suffixes. Order the one that matches your engine’s serial number.

If you’re tired of guessing part numbers and dealing with returns because the counterman read a cross-reference wrong, get the exact factory data. This catalog sits on my bench next to the coffee cup and the micrometer. Access the Factory Manual and start ordering parts that fit the first time.
