Ebro TRACTOR NACIONAL 1960 User Manual

If you’re trying to keep a 1960 Ebro TRACTOR NACIONAL running, you’ve figured out that aftermarket documentation won’t save you. I’ve seen too many guys chase vacuum leaks because some reprint had the wrong regulator settings. This is the factory-issued User Manual – 91 pages, printed March 1960 by Motor Ibérica, S.A. in Barcelona. It’s what the dealer techs used when these tractors were new. That matters.

Page 5: Specs That Don’t Leave Room for Guesswork

Section one – ESPECIFICACIONES – starts on page 5. Those are the numbers you need before you touch a wrench: compression ratios, injection timing, tire pressures, and fluid capacities. No second-guessing. If your torque wrench doesn’t match the factory spec, you’re doing it wrong. End of story.

Does This Manual Cover the Fuel Injection System?

Yes. The SISTEMA DE INYECCIÓN chapter runs from page 45 through page 48. It covers the injection pump, nozzle settings, and the vacuum governor. If you’ve ever had a diesel that won’t restart after a rebuild, you know how critical those pump timing numbers are. This manual gives you the factory procedure – not some aftermarket summary that leaves out the shim thickness.

3 Maintenance Schedules You’ll Find Inside

First: SISTEMA DE LUBRICACIÓN (page 36) – specifies the detergent diesel oils and warns against mixing detergent and non-detergent oils. That warning on page 3 is worth the price alone. Second: SISTEMA DE REFRIGERACIÓN (page 37) – cooling system maintenance, including thermostat inspection and flushing intervals. Third: SISTEMA DE COMBUSTIBLE (page 41) – fuel tank cleaning, filter replacement, and bleeding procedures. Follow them, and you won’t be replacing injectors every season.

Break-In Procedure: The Rodaje Period

Page 21 lays out the PERÍODO DE RODAJE DEL TRACTOR. This isn’t optional. New rings and bearings need a specific load cycle for the first 50 hours. The manual tells you exactly what rpm to stay under, when to change the oil, and what to check after the first 10 hours. Skip it and you’ll be pulling the head inside a year.

Hydraulic Lift: Uniones del Elevador – Page 73

The ELEVADOR HIDRÁULICO section (page 71) and its union details (page 73) cover the three-point hitch system. If your lift drifts down or won’t raise, the manual walks you through the check valve, the relief pressure, and the linkage adjustments. No guessing – you measure, you adjust, you test.

For broader context on gear-driven systems, the TRANSMISIÓN chapter (page 52) explains the manual gearbox and rear axle. If you’re new to tractor drivelines, start with Manual Transmission fundamentals on Wikipedia, then cross‑reference the chapter here. The manual assumes you know the basics – it doesn’t teach you what a clutch does.

Speaking of transmissions, the DESEMBRAGUE HIDRÁULICO AUTOMÁTICO (page 76) covers the hydraulic clutch release. That’s a feature unique to this model. Aftermarket diagrams often draw it wrong. Use the factory illustration.

When you need to diagnose a no‑start or poor power, turn to DIAGRAMAS DE LOCALIZACIÓN DE AVERÍAS starting on page 50. It’s laid out like a logic tree: symptom → check → fix. I’ve used it to track down a clogged fuel return line in fifteen minutes. That’s the difference between a real manual and a paperback reprint.

Other Ebro iterations require different documentation. For the updated 1970s models, grab the Ebro 155-E 160-E 470 684-E 1977 Workshop Manual. The articulated chassis line is covered by the EBRO A-21L, A-30L Articulated Tractor Manual. And if you’ve got a Super Ebro, the EBRO Super Ebro Instruction Manual is the one you need – different engine family entirely.

For wiring, the SISTEMA ELÉCTRICO chapter (page 82) gives the battery polarity, generator specs, and the starter circuit. A lot of old tractors get converted to 12‑volt systems. The manual shows you the original 6‑volt layout so you know what you’re changing. If you mess with the wiring without the diagram, you’ll smoke the regulator.

Compare that to a third‑party reprint: the aftermarket often copies the text but leaves out fold‑out diagrams or reduces photo resolution. This is a direct scan of the original 1960 print – you can read the part numbers and see the casting marks. That’s authenticity you can’t get from a $5 PDF from a generic site.

Understanding the Manual Transmission section requires familiarity with gear ratios. The manual gives you the tooth counts and shift fork adjustments. I’ve seen guys rebuild the transmission with the wrong main shaft bearing because they used a universal parts book. Use the factory spec.

FAQ

Is this manual in English?

No. It’s the original Spanish factory edition. If you don’t read Spanish, you’ll need a translator or a bilingual friend – but the diagrams and torque values are language‑independent.

Will this cover the Super Ebro models?

No. This manual is specific to the TRACTOR NACIONAL model produced in 1960. The EBRO Super Ebro Instruction Manual covers that separate line. Different engine, different chassis. Don’t mix them up.

You need the actual factory data that came with this tractor when it rolled off the line in Barcelona. Every spec, every diagram, every warning was written by the people who built it. Access the Factory Manual, print it, and keep it in the toolbox. You’ll thank yourself the first time you have to pull the injection pump.
