Volvo Penta MD11C, MD11D, MD17C, MD17D Workshop Manual

I have lost count of how many marine engines I have seen ruined by a backyard mechanic who thought ‘close enough’ was good enough on torque. When you are dealing with a Volvo Penta diesel, guesswork gets expensive fast. Volvo Penta MD11C, MD11D, MD17C, MD17D Workshop Manual is the factory cure for that problem. 48 pages of actual OEM data – not some aftermarket translation from a third party that left out the critical step. If you are rebuilding one of these four-cylinder marine diesels, this is the only paper that matters on your bench.

Safety Precautions – Your First Priority

Safety is not optional.Page 2 of the manual covers the basic precautions you need before pulling a wrench. Fuel system pressure, rotating parts, hot surfaces – it is all listed. I have seen guys skip this page and end up with a diesel injection line to the face. Read it. Bleed the system properly before you open anything. The manual tells you which lines to crack. Follow that order.

What the Manual Actually Covers

You get a component guide starting on page 8 that labels every major assembly. General information section tells you lubrication specs and cooling system capacities – in Imperial units, quarts and gallons. Then the real work begins. Dismantling procedures from cylinder head (page 10) through camshaft (page 14). Overhauling starts on page 15 with valve guide replacement and injector sleeve work. Over 40 pages of step-by-step that match what the factory techs used. No guessing.

Dismantling Guide: Page 10 and Beyond

Page 10 walks you through cylinder head removal on the MD11C and MD17C. Torque sequence for the head bolts is given in lb-ft. Cylinder liner removal on page 11 shows the puller tool you need. Pistons and con-rods come out after that. Timing gear removal on page 12 requires a puller and a specific locking tool – the manual gives the dimensions so you can make your own if needed. Flywheel and crankshaft sections are clear. Do not skip the crankshaft end-play check. Spec is in the manual.

Overhauling the Engine – Precision Work

Once everything is apart, the overhaul section is where the manual earns its keep. Valve guide replacement on page 15: press-in depth is given. Valve seat cutting angles for intake and exhaust – those are factory numbers. Injector sleeve removal and installation on page 17 – critical if you have a coolant leak into the cylinder. I have seen backyard guys try to epoxy the sleeve in. The manual says press it out and replace with new. That is the only correct way. Assembly of the cylinder head on page 18 lists the torque sequence and final angle turn. You need a torque-angle gauge. Get one.

3 Reasons to Choose OEM Documentation

Aftermarket manuals often skip the small details that matter. This one is a direct scan of the original Volvo Penta workshop manual. The 48 pages are exact – no reprints, no interpretations. Torque specs are printed in the margins next to the procedure. Clearances for main bearings, connecting rods, camshaft journals – all there. The centrifugal governor adjustment on page 19 is specific to the MD series. Aftermarket manuals leave that out or give generic settings. Not here.

Frequently Asked Questions

Is this manual for both MD11 and MD17 series?

Yes, covers MD11C, MD11D, MD17C, MD17D.

Does it include torque specs?

Factory torque specs are listed throughout the dismantling and overhaul sections. For critical fasteners like cylinder head bolts, the values are given in lb-ft on the assembly page. Do not rely on generic charts – these numbers are specific to the Volvo Penta casting and bolt grade. The manual also covers tightening sequences and angle torques where applicable. Page 18 has the head bolt torque sequence. If you skip this step, you will warp the head or crack the block. I have seen both. The manual also includes clearance specs for main bearings and connecting rods. You also get injector line torque values – over-tighten those and you crack the injector body. The manual gives you the exact number.

What is the publication year of this manual?

The manual does not list a publication year. It is an original OEM factory document.

Can I use this for the MD17A?

No. Covers only C and D variants.
