Steyr M9078, M9086, M9094 2005 Parts Catalog

You’ve got a Steyr diesel tractor – M9078, M9086, or M9094 – and you need a part. You pull the number off the old housing, order something from an aftermarket supplier, and it shows up wrong. Then you’re down a day, and the field work is waiting. That’s exactly why I keep a factory Steyr M9078, M9086, M9094 2005 Parts Catalog on the bench. This is the OEM catalog – 1062 pages – printed by Steyr in 2005, not some scanned reprint with blurry lines and missing pages. It’s the same book the dealer parts counter uses. No translation errors, no guesswork. If you’ve ever wasted money on a part that didn’t fit because someone copied a number wrong, you’ll appreciate what this catalog does for you.

Let me be clear: a parts catalog is not a repair manual. It won’t tell you how to rebuild a transmission. But if you’re ordering seals, bearings, gaskets, or any bolt-on component, you need the exact part number and the exploded view that shows where it goes. That’s what this book delivers. Every section – from the engine to the hydraulic system – is broken down into clear illustrations with reference numbers tied to the factory part numbers. You don’t need to guess which revision of the pump you have; the catalog covers serial number ranges and supersessions. I’ve seen too many guys skip this step and end up with the wrong clutch disc or a steering cylinder that won’t bolt up.

Parts Catalog Organization for M9078, M9086, M9094

The catalog is split into nine main groups, or hoofdsteken as they call it in the original Dutch. Each group covers a major system. Group 01 is the engine – includes the block, cylinder head, timing cover, oil pan, and all the internal rotating parts. Group 02 covers the fuel system: injection pump, lines, injectors, filters. Group 03 is the electrical system – starter, alternator, wiring harnesses, switches. Group 04 is steering and front axle – kingpins, tie rods, spindles. Group 05 handles the powertrain and rear axle – transmission gears, differential, final drives. Group 06 is brakes – discs, calipers, valves. Group 07 covers the hydraulic system – pumps, valves, cylinders, hoses. Group 08 includes the chassis, cab, and hitches – fenders, seat, three-point linkage. Group 09 is the numerical index – every part number listed with its page reference so you can find anything fast.

What Sections Are in This Parts Catalog?

You get the full TOC from the original 2005 printing. The engine section alone runs over 150 pages, subdivided by components like the cylinder block assembly, crankshaft and bearings, camshaft and timing, oil pump, and cooling system. The fuel system section covers both mechanical injection and any optional electronic controls present on later M9094 models. The electrical section includes wiring diagrams in the form of component location drawings – not complete schematics, but enough to trace a harness break if you have the repair manual alongside. The steering and front axle group includes exploded views of the steering gear, tie rods, and front axle housing. Transmission sections break down the power shuttle and the mechanical gearbox into individual parts – synchro assemblies, shift forks, shafts, and seals. Brake section includes both wet disc and dry disc variants. Hydraulic system shows the gear pump, control valve, lift cylinders, and remote valve kits. The cab section lists glass, seals, HVAC components, and wiper motors. And the numerical index at the end – that’s your time-saver: look up any part number and it tells you the page.

9 Main Sections Covering the Entire Tractor

Numbering starts at 01 and ends at 09. Each section begins with an overview page listing the sub‑assemblies covered. The catalog uses the same style as the factory service manual: clean line drawings with part numbers placed next to each component, and a table below with the part number, description, and quantity required. Every drawing includes a note about the serial number break where changes occurred. For example, the M9094 got a hydraulic pump upgrade in 2003; the catalog shows both versions with the correct serial number range. If you’re working on an early M9078, you can be sure the parts listed match your tractor’s build date. The 1062 pages also include a multilingual legend – the descriptions are in German, English, French, Italian, Spanish, Portuguese, Dutch, and Swedish. So if you’re a North American mechanic and the only hand-written notes are in German, you can still read the part numbers.

Use the Numerical Index to Find Part Numbers

When you have a part number but don’t know the group, turn to section 09 – the numerical index. It lists every part number sequenced numerically, then gives you the reference page. This is the fastest way to check if a number is still current or if it’s been superseded. I’ve pulled parts for a M9086 hydraulic valve where the index showed a superseded number – saved me from ordering a discontinued part. That index alone is worth the price of the catalog because it eliminates the cross-referencing nightmare.

Engine Section: What’s Included for the M9078, M9086, M9094

The engine group (01) covers the 4‑ and 6‑cylinder Steyr diesel engines used across these three models. You get exploded views of the cylinder block, cylinder head, valve train, timing gears, oil pan, front cover, and flywheel housing. Every seal, gasket, bolt, and plug has a part number. There’s no torque specification list in a parts catalog – that’s in the repair manual – but if you need the correct head bolt or the specific camshaft thrust washer, this is where you find it. The fuel system group (02) includes the injection pump, injectors, fuel lines, and manual primer pump. The electrical group (03) lists the starter, alternator, voltage regulator, and battery cables. The steering group (04) shows the steering column, steering gear, and tie rod ends. The powertrain group (05) includes the clutch, transmission, rear axle, and final drives. The brake group (06) covers discs, calipers, and master cylinder. The hydraulic group (07) includes the pump, control valve, lift arms, and remote valves. The chassis group (08) covers the cab, fenders, seat, grille, and hitch hardware.

This catalog is not a substitute for a service manual – you’ll still need torque specs and procedures. What it gives you is the factory part identification that aftermarket parts books get wrong. I’ve had customers bring me parts from aftermarket catalogs that were off by a millimeter or had the wrong thread pitch. Those mistakes cost time and money. With this OEM catalog, you order the exact part that was on the tractor when it left the factory. No guessing.

Is this a repair manual or a parts catalog?

It’s a factory parts catalog – not a repair manual. You get part numbers, exploded views, and quantities, not step‑by‑step disassembly or torque specs.

How do I use the numerical index to cross-reference parts?

Turn to section 09, the numerical index. Every part number listed in the catalog appears there in numerical order, with the page number where the exploded view and detail are found. If you have a part number from an old invoice or a marked-up diagram, look it up here first. The index will tell you if that number has been superseded – the catalog notes cross‑references to new numbers. This is especially useful when you’re dealing with a tractor built between 1999 and 2004 (the serial number range covered – DBD0055001 onward). You can quickly verify whether a seal or bearing is still available under the original number or if you need the updated version. It saves hours of flipping through sections.
