Volvo Parts D11B 350, D11B 390, D11B 430 2011 Technical Manual

You’ve got a D11B on the stand and no factory spec sheet? You might as well use a pipe wrench for a micrometer. The Volvo Parts D11B 350, D11B 390, D11B 430 2011 Technical Manual is what you need on the bench. I’ve torqued enough M16 head bolts to know that guessing leads to comebacks. This is the original factory document — 41 pages, published 2011, and it doesn’t waste your time with generic advice.

Valve Mechanism: Clearance and Timing

Valve mechanism section covers the overhead setup. You get the exact clearance specs for the compression rings — upper compression ring 0.40–0.55u202fmm gap, lower 1.0–1.2u202fmm. That’s critical for the D11B 430 at 2100u202fNm torque. Without these numbers you risk ring butting or blowby. The page for firing order (1-5-3-6-2-4) is also here; don’t trust a screenshot from a forum.

41 Pages of Factory Specifications

Forty-one pages of every number you need. Cylinder bore 123u202fmm, stroke 152u202fmm, swept volume 10.84u202fdm³, compression ratio 18.0:1. The Engine chapter breaks down block dimensions — lengthu202f967u202fmm, height upper block face 379u202fmm. All from Volvo Parts, not a third-party reprint. If you’re rebuilding a D11B 350, 390, or 430, these dimensions are non‑negotiable.

Fuel System: Injection Timing and Pump Specs

In the Fuel system chapter you’ll find injection timing for each power rating. D11B 350 max torque at 1080–1470u202frpm, D11B 390 at 1050–1440u202frpm, D11B 430 at 1050–1470u202frpm. That tells you where the fuel curve peaks. Without this, you’re setting timing by ear. It also covers the high‑pressure pump and injector specs. If you’re also working on the D11C family, the Volvo D11C Engine Specifications and Technical Data manual covers that. When you drop the transmission, you’ll disconnect the Manual Transmission linkage — the manual covers that step too.

Cooling System: What the Factory Says

Cooling system section: not a generic “drain and fill”. You get thermostat opening temperature, water pump torque, and hose routing. The D11B runs hot at full load — 1900u202frpm for the 430 — so Cooling system accuracy matters. Leaks show up fast in a shop. Run the manual’s specs and you avoid that.

Tightening Torques and Diagrams – The Real Deal

Tightening torques and diagrams section at the back. 26 cylinder head bolts per head, M16u202f×u202f200u202fmm. The manual gives the sequence and step values. I’ve seen shops use a single‑pass method and blow a gasket. This section prevents that. For transmission work, you’ll also need the Manual Transmission specs from the vehicle service manual. If you need more engine data, try the Volvo D13C Engine Specifications Technical Manual 2011 and the Volvo Parts L110E L120E Electrical Schematic OEM PDF.

Who Needs This Manual?

Who needs this manual? DIY guys rebuilding a D11B in the garage? It keeps you from buying the wrong parts. Fleet mechanics with a row of Volvo trucks? Saves billable hours. The technical density is high — no filler. Every number is factory verified. I’ve used Volvo Parts manuals for years; they don’t leave out steps.

FAQ

Does this manual cover the D11B 430 model?

Yes.

How do I find the torque specs for the cylinder head?

Turn to the “Tightening torques and diagrams” section near the end of the 41‑page manual. It lists the sequence and torque values for all critical fasteners including the 26 M16 head bolts. Without these numbers, you risk head gasket failure. Always use a calibrated torque wrench and follow the diagram exactly. I’ve seen too many engines come back because someone skipped the torque angle step.

Access the Factory Manual and get the numbers you can trust. No guesswork, no aftermarket copy — just OEM data from 2011. Your job, your reputation. Put the Volvo Parts Technical Manual on your tablet or print it out. Either way, you’re working with factory specs.
