Zetor 3321, 3341, 4321, 4341, 5321 2003 Parts Catalog – OEM Factory Manual

I’m Mike Callahan. 28 years in a six-bay shop in San Antonio, and I’ve lost count of how many times a parts counter guy handed me the wrong bearing because the catalog number was off by one digit. That’s why you get the factory doc. Zetor 3321, 3341, 4321, 4341, 5321 2003 Parts Catalog – 484 pages of OEM exploded views and part numbers, direct from the manufacturer. Not a scanned reprint from some third-party that swapped numbers to sell their own inventory. This is the real deal. If you’re fixing a Zetor Super tractor and you need the correct part, you stop guessing right here.

4 Models, One Catalog – Cross-Referencing Made Simple

This catalog covers the 3321, 3341, 4321, 4341, and 5321 Super models. Also includes the 6321 and 7321 Super and Super turbo variants. That means one document for a whole family of tractors. Need a piston ring for a 3341? Look it up under the engine group. Same part number might fit the 4321. The catalog groups everything by assembly – engine, transmission, chassis, body, electrical, and hydraulics. You don’t waste time flipping between five different books.

Engine Group: Crankshaft to Cooling System

Open to the MOTOR section and you get crackcase (KLIKOVÁ SKŘÍŇ – page 18), crankshaft mechanism (KLIKOVÉ ÚSTROJÍ), timing (ROZVOD), cylinder head (HLAVA VÁLCE), lubrication system (MAZACÍ SYSTÉM), and the complete fuel system (PALIVOVÝ SYSTÉM) including injection pump, mechanical governor, fuel pre-filter, transport pump, and the single-stage fuel filter. Each sub-group has its own exploded diagram with every fastener, seal, and gasket called out by Zetor part number. No cross-reference to some aftermarket catalog – it’s the original number.

Transmission and Driveline: Gearbox, PTO, Axles

You want to rebuild a gearbox? The PŘEVODOVÉ ÚSTROJÍ section covers the transmission housing (122), gearing (122a), torque multiplier (NÁSOBIČ TOČIVÉHO MOMENTU), creeper reduction (REDUKTOR PRO PLAZIVÉ RYCHLOSTI), reverser (REVERZACE), and PTO shafts at 540/750/1000 rpm. Then you get the rear half-shafts, front drive axle for 3341/4341/5341/6341/7341 models, including the Carraro axle housing, pinion and ring gear, differential, wheel hub with brake, planetary reduction, and the driveshaft. Every part number is there.

Get the Right Part Number the First Time

Third-party parts catalogs are garbage. They often renumber parts to lock you into their supply chain. This is the original Zetor factory document printed in 2003, with the same part numbers that go on the assembly line. The TOC lists over 100 groups, from the front axle console (PŘEDNÍ NÁPRAVA S KONZOLOU) to the cabin wiring (ELEKTROINSTALACE KABINY). You need a brake disc for the Knott disc brake? Group 227. Hydraulic brake for trailer? Group 238. Cab heater? Group 371. It’s all here.

One more thing about ordering: the catalog includes part number changes and supersessions right in the illustrations. You don’t have to guess if Zetor updated a part. The diagram will show the old number crossed out and the new number listed. That saves you a return trip to the dealer.

Does This Manual Cover the Fuel System?

Yes, and it’s detailed. Group 009 covers the whole fuel system – injection pump, mechanical governor, coarse fuel cleaner, transport pump, and the single-stage fuel filter (SOLO GRADO). Each component has its own exploded view with individual part callouts. Need the spring for the governor? You’ll see it on the diagram with a number you can take straight to Zetor parts.

For context on why factory documentation matters in the broader Automotive Industry Overview, remember that OEM specs are the only ones that guarantee fitment. No aftermarket catalog can claim that.

FAQ

Is this manual in English?

Yes. The catalog is printed in four languages: Czech, German, English, and French. The part numbers are universal, but the descriptions and group names appear in all four side-by-side. You won’t need a translator.

Does it include torque specifications?

No. A parts catalog shows exploded views and part numbers, not assembly torque values. For torque specs you need the factory service manual for these models.

Can I use this to rebuild my engine?

You’ll get every part number you need for a complete teardown rebuild, but this is not a step-by-step service manual. Use it to order the right parts, then get the Zetor workshop manual for clearance specs and torque sequences.

What models are covered exactly?

The title lists 3321, 3341, 4321, 4341, and 5321 Super models. However, the catalog also includes groups that reference 6321 and 7321 Super and Super turbo variants, especially in the Carraro axle sections, chassis components, and body parts. If you own a 6321 or 7321, check the specific group – most parts are shared, but some groups are marked “Z 6321, 7321” or “Z 3341, 4341, 5341, 6341, 7341.” The 2003 edition covers the full Super line up through the 7341 Super turbo.
