DAF DD 575, DF 615, DT 615 Workshop Manual

Missing a torque spec on a DAF DD 575 head bolt? Wasting shop time flipping between aftermarket PDFs that don’t match the casting? Been there. I’ve pulled more wrenches on these old DAF diesels than most techs have seen. The DAF DD 575, DF 615, DT 615 Workshop Manual is the one you need on the bench. 87 pages, OEM factory print, no reprints from third-party scanners that lose the bleed. This is the actual manual DAF Diesel sent to its Service Promotion network in February 1979.

If you’re working on a DD 575, DF 615, or DT 615, you know the castings change between series. The identity plate on the valve cover tells you the spec number—if you ignore that, you’ll order the wrong gasket set every time. Page 1 of the manual lays out the ordering parts procedure with a diagram of where the engine block type indication and serial number are stamped. That alone saves a return trip to the parts counter.

ENGINES 2: What the Factory Wants You to Know

Section 2 covers the engine assembly itself. The manual splits the content between the DD 575 and the DF/DT 615 series, calling out differences explicitly. You get the bearing clearances, piston ring gaps, and valve train specs. Fuel injection pump timing? It’s in there. The manual warns that modifications may have happened after printing, so you cross-reference your engine number with the latest dealer info. That’s not laziness—that’s DAF covering their liability. You do the same.

COMPRESSOR 6: Not an Afterthought

Many aftermarket guides skip the air compressor service. This manual devotes a full section—COMPRESSOR 6—to the unit mounted on the gearcase. You get the disassembly sequence, wear limits for the piston rings, and the torque values for the cylinder head nuts. Air system leaks kill brake response time. If you’re troubleshooting a slow air build, you need the factory clearances, not a guess.

Ordering Parts Correctly: Page 1 Detail

Page 1 includes the identity plate location and the specification numbers. It says: “If these data are missing, it is impossible to guarantee a correct supply.” I’ve seen shops order three different oil pans because they didn’t read that line. The manual also covers the service documentation information card (subgroup 0-05, page 1-3) so you can feed feedback back to DAF. Most of us never send that card, but the fact it’s included tells you the factory expected field techs to communicate issues.

87 Pages – What You Actually Get

The manual is 87 pages total, printed in English. Binding is stapled, not spiral, but the page layout leaves room for margin notes. You get sections GENERAL 0 (parts ordering, info card), ENGINES 2, COMPRESSOR 6. That’s it. No wiring diagrams, no transmission overlays—this is pure engine and compressor service. Need the Manual Transmission”>Manual Transmission specs for the truck chassis? Those are in a separate book. This one stays inside the engine bay.

Does This Manual Cover Both the DD 575 and the DF/DT 615?

Yes. Page 2 states: “All information applies both to the DD575 and to the DF and DT615 engines unless otherwise stated.” So when you see a torque value for the main bearing cap, it applies across the series unless a note calls out a difference. The specifications refer to brand-new parts. Worn threads get a different approach—the manual doesn’t cover that, so you use your experience or call the dealer. The DAF SBR 3015 Workshop Manual – Steered 3rd Axle Repair Guide”>DAF SBR 3015 Workshop Manual might help if you’re working on a steer axle, but that’s a different system.

Audience: Who Should Buy This

If you own a DD 575, DF 615, or DT 615 engine—either in a stationary pump, a generator, or an older DAF truck—you need this. Professional diesel shops should have a copy on the bench next to the DAF LF45, LF55 2010 Workshop Manual – OEM Factory Specs”>DAF LF45, LF55 2010 Workshop Manual for cross-reference. Home mechanics who skip the torque sequence on a compressor head will chase leaks all day. Don’t be that guy. Also consider the DAF LF45, LF55 2003 Workshop Manual – OEM Steering & Axle Specs”>DAF LF45, LF55 2003 Workshop Manual if your chassis work overlaps.

Source Authenticity: OEM vs Aftermarket

Aftermarket manuals summarize. They drop the footnote about specification numbers. They redraw the identity plate diagram and sometimes reverse the image. This is a direct scan of the original DAF Diesel Service Promotion booklet. The watermark on page 2 says “February 1979.” You see the original font, the original torque charts, the original warnings. If you’re a shop that gets audited, you need the OEM document to back up your procedure. This is that document. Related reading: Manual Transmission”>Manual Transmission service intervals are not covered here, so verify separately.

Can I use this manual for the DD 575 and the DT 615 interchangeably?

Yes, unless a specific note says otherwise. The intro on page 2 states all information applies to both unless stated.

Where do I find the torque specs for the compressor cylinder head?

Section COMPRESSOR 6 lists them. The manual tells you the sequence and the final torque value in lb-ft.

Does the manual include wiring diagrams or fuel injection pump calibration data?

No. This is a workshop manual covering disassembly, inspection, and assembly of the engine and compressor. Fuel pump service requires a separate injection pump manual from DAF.

What if my engine number isn’t listed in the ordering parts section?

Contact your DAF dealer using the information on the identity plate. The manual’s ordering procedure on page 1 requires both engine number and specification number to guarantee correct parts.

You’ve got the engine. You’ve got the tools. Now get the data that matches the casting. Access the Factory Manual and keep it in your tablet or print it for the bench. Your torque wrench will thank you.
