Deutz BFM 1012, BFM 1013 Workshop Manual – Factory Specs for 488 Pages

I’ve had it with aftermarket manuals that list a torque spec off by 20 lb-ft and leave you chasing oil leaks on a rebuilt engine. This Deutz BFM 1012, BFM 1013 Workshop Manual is the real deal – a direct scan of the factory binder, 488 pages, no paraphrasing, no third-party editing. It covers both the BFM 1012 and BFM 1013 inline diesel engines in full detail, from specification data in Chapter 1 to the special tool list in Chapter 5. If you’re doing a full rebuild on a forklift, generator set, or agricultural machine powered by one of these Deutz engines, this is the document you need on the bench.

The table of contents is laid out in four languages (German, English, French, Spanish) – but the English in the procedures is clear and direct. You get five main sections: Specification data, Checking and adjusting, Repair of components, Disassembly and reassembly of the complete engine, and Tools. No fluff, no vague diagrams lifted from a parts catalog. Each section matches the factory workflow. For example, when you hit Chapter 2 (Prüfen und Einstellen / Checking and adjusting), the manual walks you through valve clearance checks with the engine cold, using the exact feeler gauge thickness called for by Deutz. Don’t guess; the spec is printed there.

What Chapters 1–5 Cover in This Deutz Workshop Manual

Chapter 1, Specification data, gives you all the bore, stroke, firing order, compression pressure, and injection timing numbers that make the engine run correctly. Chapter 2 – Checking and adjusting – includes injector pressure tests and governor adjustments. Chapter 3, Repair of components, breaks down the cylinder head, fuel injection pump, and oil pump into step-by-step overhaul procedures. Chapter 4 covers complete engine disassembly and reassembly, including main bearing cap torque sequences. Chapter 5 lists the required special tools – part numbers included – so you know exactly which puller or holder you need before you start. Page numbers run from the foreword through the tool appendices. Need the charge pressure? Page 73. Need the crankshaft end float spec? It’s in Chapter 1 under “Technische Daten.”

Checking and Adjusting: Why the Factory Procedure Matters

I’ve seen junior techs try to set the valve clearance on a BFM 1013 using a generic diesel manual. They end up with the wrong lash and a ticking noise that never goes away. This manual gives the cold clearance for intake and exhaust valves in metric and imperial. It also shows the exact sequence for adjusting the injector timing with the timing pin hole location. Follow Chapter 2 step by step, and you won’t have to tear the front cover off again because you missed a mark. The manual includes cross‑section drawings that show the fuel cam orientation. You can’t get that from a third‑party summary.

Torque Specs and Tool Lists – Not Guesswork

Every critical fastener in a Deutz BFM 1012 or 1013 has a torque value. Cylinder head bolts, main bearing caps, connecting rod nuts – they’re all in the manual. The torque values are listed in their original factory units (Nm) with lb‑ft equivalents. I always cross‑check my torque wrench calibration against the manual before a head job. And the tools chapter lists the Deutz part numbers for things like the flywheel lock and the injector puller. If you don’t have those, the manual also tells you which commercially available tools work. This isn’t a generic “use a 12‑point socket” tip – it’s specific. The same applies to the assembly sequence for the front gear train. Miss a step and you’ll have timing issues. The manual shows the order.

If you’re working on a related Deutz engine family, you might also want the Deutz BF6M 1015 CP 2003 Workshop Manual – 660 Pages Factory Specs for the larger V‑6 variant, or the Deutz 912 B/FL911 W/913 C 1991 Workshop Manual – OEM Specs for the older air‑cooled series. For the six‑cylinder turbocharged models, check the Deutz BF6L513R, BF6L513RC 1988 Workshop Manual.

Source Authenticity – Why I Won’t Touch Aftermarket Deutz Manuals

I’ve been burned by aftermarket manuals that copy the table of contents but replace the real spec tables with generic data. This document is an original factory print from Deutz AG – the same one used in dealerships. The file is scanned from the paper binder with all the original watermarks and page numbers intact. You can verify the authenticity by checking the part number on the front cover: 0297 7438. The manual even includes the copyright notice from Deutz forbidding reproduction. That’s how you know it’s the real thing. If you need a wiring diagram that isn’t here because this manual is engine‑only, you’ll want a separate Manual Transmission manual for the drivetrain, but for the engine itself every spec is original.

When you’re doing a full rebuild, there’s no substitute for the factory disassembly sequence. The manual covers the BFM 1012 and BFM 1013 with the same level of detail – no shortcuts. They didn’t leave out the steps for removing the vibration damper or the rear oil seal. Chapter 4 (Demontage und Montage, Motor komplett) shows the exact order for separating the flywheel housing and the timing gear case. Follow that and you won’t damage the O‑rings or the dowel pins. I’ve seen a technician break a timing cover because he pried on it instead of using the correct puller. The manual warns you about that.

Does This Manual Cover Both BFM 1012 and BFM 1013?

Yes. The manual is titled “BFM 1012/1013” and covers both the naturally aspirated and turbocharged variants within those families. The specification data includes both the BFM 1012 and BFM 1013 engine codes. If your engine number starts with 1012 or 1013, you’re covered. The manual also references the different injection pumps and cylinder head versions used across the series. I’ve used it on a BFM 1013F found in an older generator set, and every spec matched. For transmissions, you’ll need a dedicated Manual Transmission guide, but for the engine block and its components, this is the only manual you need.

Frequently Asked Questions

Is this manual in English?

Yes. The manual is multilingual with English on facing pages.

Does it include torque specs for the cylinder head?

Yes, the cylinder head bolt torque sequence and final angle are in Chapter 1 specification data and detailed in the repair section. You also get the tightening stage values in Nm and lb‑ft.

Can I use this manual for the BFM 1012E with electronic injection?

This manual covers the mechanical injection pump versions of the BFM 1012 and 1013. If you have an electronic unit pump (EUP) system, some of the specification data for injection timing and governor adjustments will differ. The manual still covers the engine structure – block, crank, pistons, etc. – but for the electronic control system you’ll need the separate Deutz EMR service documentation. Check your engine serial number against the manual’s identification section before assuming full coverage.

How many pages is the PDF?

488 pages including the multilingual foreword and tool appendix.

This is the manual I keep on my tablet in the shop. No searching the internet for a spec that might be wrong. Access the Factory Manual, read Chapter 2 before you touch the valves, and you’ll have the engine running right the first time.
