Uralaz 4320, 4420 1981 Parts Catalog – Factory OEM Specs for Russian Military Trucks

If you’re working on a Ural-4320 or Ural-4420 and you’ve been guessing part numbers from a blurry copy or chasing aftermarket listings that don’t line up, you already know the headache. This Uralaz 4320, 4420 1981 Parts Catalog from Zapchastexport is the only document that gives you the official Soviet factory numbering for every bolt, bracket, and bearing in these trucks. It’s 360 pages of straight-up factory data – no interpretation, no guesswork.

10 Component Groups for Accurate Parts Identification

The catalog uses the Soviet 10-group classification system. Each group covers a major system: engine (group 10), clutch (16), transmission (20), transfer case (22), drive axles (24), suspension (30), steering (33), brakes (35), electrical (37), and frame/body (50). Within each group, parts are listed in numeric order with exploded-view illustrations. This structure lets you find the exact part number for everything from a cylinder head bolt to a transmission seal.

What Does the Guide to Catalog Cover?

Page 3 of this manual contains the “Guide to Catalog” section, which explains how to read the part numbering system. It breaks down the meaning of each digit in the part code, shows examples for both the 4320 towing truck and the 4420 bolster truck, and explains how to cross-reference part numbers when a superseded or updated part exists. If you’ve ever been confused by Soviet-era coding, this page alone is worth the price.

OEM Fastener Callouts and Thread Pitches

Fasteners matter. A wrong bolt grade can strip or snap under load. This catalog lists every fastener by its official factory part number, including bolt length, thread pitch, and strength grade. When you’re torquing head bolts on a KamAZ-375 engine, you need the correct washers and bolts – not some generic substitute. The catalog gives you the exact callout so you can source the right part or cross-reference to a standard metric equivalent if needed.

3 Reasons to Stick With the 1981 Factory Edition

First, aftermarket parts catalogs often re-number parts or omit supersessions. This original 1981 print includes all factory updates and changes up to that year. Second, the Soviet system used unique numbering that doesn’t map directly to Western catalogs – you lose fidelity with every translation or reinterpretation. Third, the paper quality and printing in the original Soviet edition are actually superior to many digital copies; the illustrations are clear and the tables are readable even after decades.

Audience Fit: Who Should Buy This Catalog?

Fleet mechanics maintaining a military surplus Ural-4320. Home garage enthusiasts restoring a bolster truck. Parts counter staff who need to verify a number without relying on aftermarket databases. If you touch these vehicles, you need this catalog. Without it, you’re guessing – and guessing on a Soviet truck means mismatched threads, wrong seal sizes, and weeks of waiting for the wrong part.

For disassembly and assembly torque sequences, pair this catalog with the URALAZ 4320-02 Motor Truck Service Manual. That manual gives you the step-by-step procedures; this catalog gives you the parts.

Source Authenticity: Official Zapchastexport Print vs. Aftermarket

This is a direct scan of the factory-issued catalog published by Zapchastexport in 1981. It includes all three languages – Russian, English, German – as seen in the original. Aftermarket compilations often drop the English columns or combine pages. You get the exact layout the Soviet engineers intended. If you work on vintage agricultural equipment, check out the Massey-Harris-Ferguson FF 30 GS 1957 Parts Catalog | OEM Fastener Guide for a similar level of fastener detail. But beware of aftermarket parts catalogs like Futura Wear Technology Parts Catalog that substitute generic part numbers – stick with the OEM source.

The original Soviet print is the only reliable source.

The KAMAZ-375 engine is a 4-stroke internal combustion engine; you can read up on Internal Combustion Engine theory for background, but the parts are what matter on the workbench. For context on the lineage of these trucks, see the Automotive Industry Overview.

FAQ

Does this catalog include torque specifications?

No, it only lists part numbers and fastener grades, not torque values.

Can I use this for the Ural-4320 with a different engine?

Yes, but verify the engine group sections. The catalog covers the KAMAZ-375/19. If your truck has a different engine, cross-reference the part numbers with your engine’s factory numbers.

How are the part numbers organized in this catalog?

The catalog uses the Soviet 10-group classification system. Each part number contains a 7-digit code plus a suffix. The first two digits indicate the vehicle model (43 for 4320, 44 for 4420), the next two digits indicate the group (10=engine, 16=clutch, etc.), and the last three digits identify the specific part. The guide on page 3 explains this in detail, with examples for both the towing truck and bolster truck variants. You’ll find exploded view illustrations with numbered callouts that match the parts list tables. The tables include the part number, description, quantity per vehicle, and sometimes the number used per assembly. This system allows you to order the exact part from any Soviet-era supplier, provided you have the original number.

Is this catalog available in English?

Yes, the catalog includes parallel English, Russian, and German text.
