Zetor 4911, 5911, 5945, 6911, 6945 Parts Catalog – Factory OEM

If you’ve ever tried to order a water pump for a Zetor 6911 and ended up with the wrong casting, you know exactly why this catalog exists. 385 pages of factory-issued part numbers, exploded views, and group-level breakdowns. No aftermarket interpretations, no third-party re-labels. This is the same document the dealer used when your tractor was still under warranty. I don’t care if you’re rebuilding a 4911 you found in a barn or sourcing a valve for a 5911 that’s still pulling a disk – start here or waste money somewhere else.

Valve Gear – What the Manual Covers (Page 25)

Group 04 in the table of contents is labeled “Převod / Valve Gear / Distribution / Distribución”. That’s not just a list of rocker arms. It includes the entire valve train: pushrods, tappets, camshaft bearings, and the timing gear. Each component has its own reference number tied to the factory Zetor casting. Need a valve stem seal? The exploded drawing on page 25 shows the exact placement and the OEM part number. You won’t have to measure anything – just match the index and order.

Crankcase and Cylinder Head: Two Separate Groups, Two Separate Pages

Group 01 splits the crankcase into two sections (page 11 and page 15). The cylinder head is group 04 (page 31). Why does that matter? Because the crankcase on a Zetor 5945 may share internal components with the 6911, but the head gasket might be a different thickness. This catalog shows each variant with its own parts listing. Look at the “Bloque motor” section – you’ll see the same casting but with different suffixes depending on whether the engine is naturally aspirated or turbo’d. The only way to catch that is by using OEM documentation.

Double Clutch Assembly – Page 69

Group 11 covers the double clutch (“Spojka dvojitá / Doppelkupplung / Double Clutch”). If you’ve ever pulled a transmission on a 6911, you know the clutch pack has two separate discs: one for the main drive, one for the PTO. The exploded view on page 69 shows both clutch plates, the release bearing, and the springs. More importantly, it lists the part numbers for the clutch hub and the driven plate. Buy the wrong plate and it either slips or won’t disengage. The manual’s table will tell you which model uses which part – no guessing.

Fuel System (Page 61) – Injection Nozzles and Filters

Group 08: Palivový systém / Fuel System. This covers everything from the lift pump to the injectors. For the 4911 and 5911, the injection pump is different from the 6945. The catalog lists the nozzle holder assembly, the delivery valves, and the high-pressure lines. Page 61 shows the filter head mount and the primary filter element – part number is cast right in the drawing. If you’re sourcing a replacement pump, cross-check the serial number against the engine group listed in the table. The manual doesn’t guess – it cites the exact OEM specification.

Torque Specifications and Bolt Grades

You won’t find torque values in a parts catalog – that’s what the service manual is for. But this catalog does show bolt grades and lengths for every major fastener. Look at the rear half-axle with portal (page 137). The bolts that hold the final drive housing are listed with a grade rating and a thread pitch. When you match those bolts to OEM replacements, you don’t overtorque and strip the threads. Cross-reference those part numbers with your supplier before you start cranking down with a breaker bar.

Who Needs This 385-Page Beast

Home-garage guys who bought a used Zetor from an auction. Small farmers who keep three generations of tractors running. Shops that bill hourly – this catalog kills parts-chasing time. If you’re rebuilding a 5945 transmission, you need to know which shifter fork goes where. The gearbox group (page 83) shows the shafts, layshafts, and splined reducers. No diagram is repeated – every variant has its own page. That’s 385 pages of dense, factory-verified information.

OEM vs Aftermarket: Why This Catalog Wins

I’ve seen aftermarket parts books where the exploded drawing is copied from a 1970s manual and the part numbers are wrong. This catalog is the original Zetor print – multiple language headings but one source. The table of contents starts with “Vysvětlivky k překladnému katalogu” – the explanatory notes. Those notes tell you how to read the reference numbers. No translation errors, no “compatible with” fudge. If the book says “Zetor 4911” on the cover, every bolt in the crankcase section (page 11) matches that engine family.

Does this parts catalog include service procedures like torque specs?

No. This is a parts catalog – it lists components and their OEM numbers. Torque values and repair steps are in the factory service manual.

How do I use the exploded views to order parts?

Find your tractor model in the group index. For example, group 07 (lubrication system) starts on page 37 for the Z 4911, Z 5911, Z 6945. Each drawing has reference numbers. Match those numbers to the parts list on the same page or the following page. The part number is the OEM casting number – take that to any dealer. Do not substitute based on appearance; the catalog shows the exact variant for your specific serial number range. I’ve seen too many people order a Zetor 5911 oil pump that was actually for the 5945 because they guessed by shape – the catalog ends that nonsense.

You need one document that stops the parts-chasing headache. Access the Factory Manual and keep a copy on your workbench or tablet. When you’re elbow-deep in a 6911 differential, you’ll thank yourself for having the correct part number on page 113.
