Zetor 3320, 3340, 4320, 4340, 5320 2003 Parts Catalog

If you’re ordering parts for a Zetor 3320, 3340, 4320, 4340, or 5320, you need the factory parts catalog. Not a reprint, not a third-party guess. This is the 2003 edition, 312 pages, covering every assembly from the crankcase to the cab. I’ve spent 28 years in a shop and I’ve seen what happens when someone orders a part off a fuzzy photocopy. Don’t be that guy.

What the Crankcase Section Tells You (Page 18)

Section 002, labeled KLIKOVÁ SKŘÍŇ, starts on page 18. That’s the crankcase assembly. The catalog gives you exploded views with every bolt, seal, and bearing called out by Zetor’s own part number. You want the main bearing set? The illustration shows exactly which parts go where and the correct quantity. No guessing if a seal is right-hand or left-hand thread. The factory drew it so you don’t have to interpret a mis-scanned aftermarket copy.

Finding the Right Part: From the Fuel System to the Rear Axle

Flip to page 38 for section 009 PALIVOVÝ SYSTÉM — the fuel system. Injection pump components, lines, filters — all with exploded diagrams. Go to page 117 for section 28 ZADNÍ POLOOSA S PORTÁLEM (rear axle with portal). That’s where you find the planet gears and axle shafts. Every section follows the same layout: a numbered diagram, a corresponding parts list with Zetor part numbers, quantities, and often supersession notes. If you need a hydraulic pump, section 422 on page 151 gives you the independent pump assembly. The catalog covers the entire tractor — from the clutch (section 11, page 56) to the cab wiring (section 58, page 192).

Why This Is Not a Service Manual (and Why That Matters)

This is a parts catalog, not a repair manual. That’s not a flaw; it’s a difference in purpose. You can’t find torque values or removal procedures in here. What you do find is accurate, OEM-verified part numbers that match your tractor’s serial number range (production numbers listed on page 2). Trying to rebuild a transmission without the correct parts diagram is a waste of time. This catalog gives you the blueprint for ordering — nothing more, nothing less. Pair it with a genuine service manual, and you have a complete setup.

Who Needs This Catalog

DIY mechanics who own a Zetor 3320, 3340, 4320, 4340, or 5320 will save money by ordering the right part the first time. Tractor salvage yards need this to identify what they’re pulling off a donor. Shop owners — if you have a customer with one of these tractors, having the factory parts catalog on your bench means you can quote parts accurately and avoid the headache of wrong returns. I’ve had guys come in with a bag of random bearings because they used a generic parts list. Don’t do that.

Source Validity: OEM Factory Documentation

This is a direct scan of the original Zetor spare parts catalog printed in 2003. The OCR excerpt on the first page shows the multilingual title in five languages — it’s the same document Zetor dealers used. Compare that to aftermarket catalogs that re-draw the diagrams and often drop details. The factory document shows every clip and O-ring. For example, the “KLIKOVÉ ÚSTROJÍ” (crankshaft assembly) section on page 26 includes the exact crankshaft part number. No aftermarket reprint has that level of accuracy. If you are serious about keeping your tractor running, use the real thing.

Frequently Asked Questions

Does this parts catalog include torque specifications?

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

Can I use this catalog to rebuild my engine?

You can use it to identify every part you need for a rebuild — pistons, rings, bearings, gaskets — all with factory part numbers. But you still need a service manual for clearances, torque sequences, and assembly procedures. The exploded views help you see how everything fits together, but the catalog does not contain repair steps. For a full rebuild, get both documents.

Stop ordering parts by guesswork. The factory Zetor Parts Catalog is the only reliable source for the 3320 through 5320 series. Every part number has been verified against the original production runs. Access the Factory Manual and keep your tractor in the field.
