Zetor 5711, 5718, 5745, 5748, 6711 1976 Parts Catalog

You’re on the hook for a Zetor 5711 that came in with a blown PTO seal. The owner handed you a photocopy of a parts list from some online forum — blurred, torn at the fold, and missing half the torque values. You’d rather eat a handful of 10mm sockets than work off that junk. What you need is the original 1976 Zetor 5711, 5718, 5745, 5748, 6711 1976 Parts Catalog, direct from the factory. 383 pages of exploded-view diagrams, factory part numbers, and cross-references that don’t lie. I’ve been wrenching for 28 years, and I won’t touch a rebuild without the OEM book — aftermarket reprints are trash because they drop out the critical casting numbers.

Engine Bonnet and Sedodla Coverage

Every Zetor in this lineup — the 5711, 5718, 5745, 5748, and 6711 — shares the same block architecture, but the sheet metal and seating changed across years. The catalog opens with the Motorkenvebrmg Engine Bonnet Carénage Capotaje del motor section. That’s where you’ll find the hood hinge hardware, grille inserts, and latch springs. Right after that comes the “Sedodla” entries — the seat assemblies. There are four variants: standard seat on the 5711/5718/6711/6745, then three separate Aerolastic seat pages for different chassis codes. If you’re trying to match a seat cushion for a 5745, the wrong sub-section will send you chasing a part number that doesn’t exist. Page 53 starts the seat group — don’t skip forward until you verify your model’s suffix.

Electrical Equipment: Two Sections

The Elektroloka I and Elektroloka II chapters cover the full wiring harness, alternator, starter, lights, and switches. Elektroloka I (page 243) handles the base electrical equipment — battery cables, ignition switch, fuse box. Elektroloka II (page 269) dives into the secondary circuits like the work light relay, flasher unit, and the specific harness for the 5711/5745/6711/6748 chassis. The manual splits the diagrams by chassis suffix, so if you’re chasing a short on a 5748 you need the “Elektroloka Il (2 5711, 2 5745, 2 6711, 2 6748)” sub-section on page 272. Don’t waste time flipping through generic wiring — use the model-specific index.

PTO Shaft Assembly for 540 and 1000 RPM

Page 273 shows the Vîvodový hričel pro 540 a 1000 ot./min. — the PTO shaft assembly with both speed options. The catalog breaks down every bearing, seal, shift collar, and snap ring. If you’re rebuilding a PTO and you use an aftermarket bearing from a general ag supplier, the shaft diameter tolerance might be off by 0.002 inch. That’s enough to chew up the housing in 200 hours. The OEM part number cross-reference in this catalog gives you the exact dimensions — no guesswork. The belt pulley drive for the 5745 and 6748 models (page 60) is covered separately: Pohonová řemenice and Pohonový řemenový řemen. Check those sections before ordering a replacement mower drive belt.

Does This Manual Cover Your Zetor Model?

Yes. The catalog explicitly lists the 5711, 5718, 5745, 5748, and 6711 tractors. The 6745 and 6748 are also included in the body of the document (the title page mentions them under the 6711/6718 line). Every component — from the Blatníky a podlaha (fenders and floor pan) to the Vzduchové brzdy (air brakes) — is broken down by model suffix. If you’re working on a 5711 with a non-original engine swap, the catalog still gives you the factory part numbers for the original engine mounting hardware. You’ll need the serial number to narrow down the exact revision, but the exploded diagrams show you where each bolt goes.

3 Reasons to Choose OEM Documentation Over Aftermarket

First, the casting numbers and supercession history. Aftermarket catalogs often reprint a single revision, missing the updates that Zetor released in late 1976. This factory catalog includes all production changes up to the print date. Second, the Normální výstroj a náhradní díly (standard equipment and spare parts) section lists the common maintenance items — oil filters, fuel filters, gasket sets — with original Zetor part numbers. Third, the index at the back lets you cross-reference by part number across all five models. You don’t get that in a 50-page aftermarket summary. If you’re restoring a 5748 for a customer’s vintage tractor pull, this is the only document that guarantees the part you order will fit without filing, grinding, or cursing.

Air Brakes and Safety: Factory Specs Only

The Vzduchové brzdy section (page 307) covers the air brake system used on some configurations. Torque specs for the brake chamber mounting bolts are given in the original metric values — don’t convert them yourself. The manual also includes the Bezpečnostní kabina (safety cab) for cabbed models like the 5718/5748/6718/6748. That section lists the roll bar hardware, seat belt anchor points, and glass part numbers. If you’re reinstalling a cab on a 5748, the seal part number for the rear window is on that page. Use anything else and you’ll get a dust leak inside two weeks.

FAQ

Will this catalog help me rebuild the engine on a Zetor 6711?

It’s a parts catalog, not a service manual. It won’t give you assembly sequence or torque values. For that, get the Zetor 4712-6748 Workshop Manual which covers disassembly and reassembly step-by-step.

What if I need part numbers for the hydraulic system on a 5718?

The hydraulic system sections — Zvedací mechanismus and Rozvadeč — are included with exploded views and part numbers. The catalog covers the lift linkage, control valve, and hydraulic pump mounting. For older 5711 models without power steering, the Různé drobné doplňky section lists the reservoir cap and filter housing. If you’re missing a hydraulic hose, the catalog doesn’t give hose length — you measure the old one and order by the generic diameter. But the fitting part numbers are correct if you need to replace a steel tube. Cross-check your chassis code against the model suffix before ordering any seal kit; the 5718 uses a different O-ring size on the spool valve than the 5745. That information is buried in the exploded view callouts, not in the text. Study the diagram carefully.
