Someca 800 1969 Training Manual

Let’s get one thing straight – I don’t hand a junior tech a reprint and tell them to figure it out. This Someca 800 1969 Training Manual is the genuine factory document. 252 pages of French OEM specs. No photocopies, no third-party translations. If you’re restoring a Someca 800 and you care about getting the injection timing right, the clutch free play, or the differential preload, this is what you need on the bench.

Engine Overhaul Coverage

Section A of the TOC breaks down the entire engine. Starts at A0.01 with the block and supports, then works through A1.01 cylinder head and block, A1.03 crankshaft and flywheel, A1.05 connecting rods and pistons. Each sub-section has exploded diagrams with part numbers and the factory assembly sequence. The injection system gets its own deep dive from A2.24 to A2.27 – fuel pump, injector holder, mechanical governor. If you need to rebuild the injection pump on this tractor, you follow A2.27, not a generic diesel pump guide.

Transmission: What the Manual Covers

Page 3 shows the transmission chapter index – B1 clutch control, B1.05 clutch detail, B1.25 reduction gear. Then the gearbox internals: B2.04 gear train, B2.05 central reduction, B3.01 transmission shaft. The differential lock and lateral reduction are in B4 sections. You get the actual OEM tooth counts, shim thicknesses, and bearing preload specs. No guesswork on gear alignment.

Where to Find Torque Specs

Every bolted joint in this manual has a torque value – but don’t expect a single page listing everything. Torque specs are embedded in each component section. For example, cylinder head bolt torque is in the A1.01 assembly procedure. Wheel lug torque is in D3.16. Use the table of contents on page 4 to navigate. That page gives you the full structure – engine, transmission, brakes, steering, hydraulics, electrical, body. Find the section, find the torque.

8 Systems Covered in This Training Manual

• Moteur (Engine) – complete disassembly and reassembly with injection
• Transmission – gearbox, reduction gear, differential, PTO
• Freinage (Brakes) – foot brake system and handbrake
• Direction (Steering) – mechanical and power steering hydraulic
• Organes subsidiaires (Hydraulics) – lift pump, valve block, 3-point hitch
• Installation électrique – starting, lighting, instruments
• Carrosserie (Body) – hood, fenders, battery tray
• Siège (Seat) – driver’s seat assembly

Each system has its own set of detailed drawings and step-by-step removal/installation procedures. The electrical section includes wire colors and routing for the 1969 harness.

Is This Manual for You?

If you’re a DIY mechanic working on a vintage Someca 800, this is the only documentation that matches factory tolerances. Workshop owners: keep this on the shelf for your techs so they don’t waste time cross-referencing aftermarket data. Beginners – this manual assumes you know how to use a torque wrench and a micrometer. It doesn’t hold your hand, but it gives you the numbers you need. For related Someca models, check the Someca 20 D, 25 D 1966 Parts Catalog – OEM Factory Parts Manual and the Someca T.P.S. 1962 Parts Catalog for parts breakdowns. The Someca SOM 55 Parts Catalog – OEM Parts Breakdown also covers a different series.

Factory Documentation vs. Aftermarket Reprints

I’ve seen too many jobs go wrong because someone used a scanned reprint with faded numbers. This is the original training manual from Someca, 2nd edition, December 1969, reference 10.681. Only 200 copies were printed. The binding is solid, the drawings are crisp. Third-party manuals often skip the hydraulic lift section or the power steering pump detail. This one has E2.20 to E2.35 for the full hydraulic lift and D2.11 for the power steering control. Don’t trust a generic tractor manual with your Someca 800.

Does this manual cover the fuel injection pump?

Yes. Section A2.24 through A2.27 detail the injection system.

Can I use this manual for a different Someca model?

This manual is specific to the 800 model. The factory training manual for the 1969 800 covers engine, transmission, hydraulics, and electrical. While some components may be similar to other Someca tractors, torque specs, part numbers, and adjustments are unique to the 800. Using it for a different model like the Someca 20 D or 25 D could lead to incorrect assembly and failure. For those, look at the Someca 20 D, 25 D 1966 Parts Catalog – OEM Factory Parts Manual which covers parts breakdowns for that series.
