YMZ 650.10 2009 Parts Catalog – What the Factory Gave the Parts Counter

If you are ordering parts for a YMZ 650.10 diesel and you are not holding this catalog, you are gambling with someone else’s money. I have seen guys slap on a “compatible” water pump from a different serial range, then spend a Saturday chasing a coolant leak that cost them a head gasket. This catalog – 72 pages, published 2009 – is what the parts counter at Yaroslavl Motor Plant uses. It lists every fastener, every gasket, every electronic sensor by its original part number, with explosion drawings that show you exactly where it goes. No translation guesswork, no “fits like OEM” nonsense. You get the real number.

The index starts on page 4 with the table of contents – you can jump straight to “Блок цилиндров” (cylinder block) or “Турбокомпрессор.” Every section uses numbered callouts that correspond to a row in the spec table. Page 3 explains the coding system: a six-digit number with a dash and a coating code (П = no coating, П2 = phosphate and oil, П29 = zinc plating). You need a bolt for the oil pan? Look up the drawing, grab the number, order that exact coated fastener. Not a standard hardware-store bolt. That matters when you are torquing into an aluminum block.

What the Catalog Covers – 7 Major Assembly Groups

This is not a repair manual. It is a parts identification catalog – something you keep open next to the phone when you call the dealer. The table of contents lists these groups:

• Engine assembly configurations for MAZ and Ural trucks
• Cylinder block, side cover, front cover, flywheel housing
• Crankshaft, connecting rods, flywheel, damper and pulley
• Cylinder-piston group, cylinder head, gasket, valve train
• Camshaft, pushrods, tappets, timing gears
• Intake/exhaust manifolds, turbocharger, heat shields
• Cooling system (water pump, thermostat, fan drive, belt tensioners)
• Lubrication (oil pump, filter, level indicator, cooling nozzle)
• Fuel system (pump, injector, high-pressure lines, low-pressure system, filters)
• Electronic control unit and wiring harnesses
• Engine brake, air compressor, starter, alternator, mounts

Each group has an exploded diagram with part numbers. You match your engine serial number to the configuration list.

Does This Manual Cover Your Engine Serial Number?

The YMZ 650.10 was built in multiple revisions for different truck builders – MAZ in Belarus and Ural in Russia. The catalog breaks those out on separate drawing pages. If your engine serial falls within the range listed in the introduction, you are covered. If you have a later revision with a different turbo mount, you need the updated supplement. The catalog notes that parts with a 10, 20, 30 suffix are not interchangeable with earlier versions of the same base number. That is the kind of detail that saves you from ordering a water pump that bolts up but has the wrong impeller clearance.

Interchange Codes – Read the Suffix Before You Order

One of the most useful features is the suffix system explained on page 3. A part number ending in -01, -02, -03 means those variants are interchangeable with each other. Ending in -10, -20, -30 means they are not interchangeable with the earlier version. I have seen guys ignore that, install a -10 crankshaft damper on a block that was machined for the -00 version, and end up with a wobble that killed the front seal in 200 miles. The factory documented this for a reason. Use it.

OEM vs. Aftermarket – Why This Catalog Wins

Aftermarket parts catalogs re-draw the diagrams, re-number the parts, and often drop the coating spec or the supersession chain. This is the original OEM print from the Russian factory – scanned, not re-typeset. You get the actual part numbers that came on the production line. When you call the dealer and read them the number off this PDF, they know it is right. That cuts the back-and-forth to zero. If you have a YMZ 238Б/238Д, check out the YMZ 238Б/238Д 2002 Parts Catalog”> or the YMZ ЯМЗ-236ДК/238АК 2002 Parts Catalog”> for similar coverage. For vintage equipment, the Massey-Harris-Ferguson FF 30 GS 1957 Parts Catalog | OEM Fastener Guide”> is another example of factory-original documentation.

Who Actually Needs This Catalog?

Home garage guys who are rebuilding a military-surplus Ural truck. Fleet mechanics maintaining MAZ dump trucks. Anybody who has ever stood at a parts counter with a greasy scribbled number and watched the clerk shrug. You need this PDF because it gives you the factory diagram, the correct part number, and the interchange code all in one place. No more blurry photocopies from 2005. No more “I think this is the right thermostat.” You open the fuel system section, find the injection pump drive, and order the exact coupling.

FAQ – Four Questions That Come Up Every Week

Does this include torque specs?

No. This is a parts catalog, not a service manual. You need the factory repair manual for torque values. This catalog gives you the part numbers for the gaskets and bolts you will torque.

Can I use this for a YMZ 650.10 built after 2009?

Maybe. The catalog reflects production as of February 2009. Later revisions may have different part numbers. Check the suffix codes – if your engine has a higher serial number range, you may need the supplement. The catalog itself warns that changes are ongoing.

The part number I need is missing from the TOC – where do I look?

Check the “Номерной указатель” (numeric index) at the end of the PDF. It lists every part number in the catalog and tells you which drawing page it appears on. That index alone saves you from flipping through 72 pages.

What is the coating code П29?

Zinc plating.

Getting the right part the first time means you do not waste a Saturday chasing a mismatch. That is what this PDF gives you. Original OEM documentation – no reprints, no aftermarket rewrites.
