Volvo Penta TAD650VE, TAD660VE 2006 Parts Catalog

Look, if you’re digging into a Volvo Penta TAD650VE or TAD660VE and need to sort out which head gasket or valve you’re looking at, you need the factory parts breakdown. Not some aftermarket list with part numbers that don’t match. This 2006 Parts Catalog is the real deal. 100 pages of OEM data, direct from Volvo Penta’s own documentation. I’ve seen guys order the wrong valve stem seal because they trusted a third-party cross-reference. Don’t be that guy.

Cylinder Head Components for TAD650VE

Page 2 of this catalog gives you the exploded view and full parts list for the TAD650VE cylinder head assembly. You get part numbers for the cylinder head (exch), valve seats, springs, collets, rocker arms, and the critical head gasket. Three thickness options are listed: 1.24mm, 1.34mm, and 1.44mm. Without those exact measurements, you’re guessing. That leads to compression leaks or burnt valves.

What You Get on Page 4 for the TAD660VE

The TAD660VE shares many components with the 650, but the head gasket thicknesses differ: 1.26mm, 1.36mm, 1.46mm. Page 4 also includes the solenoid valve, O-rings, and support rings specific to this model. If you’re swapping a head or building an AGR-module engine, those parts matter. The catalog uses reference numbers and a clean table — part number, quantity, description. No ambiguity.

Why OEM Parts Catalog Beats Aftermarket Numbers

Aftermarket catalogs often renumber parts, drop superseded items, or skip the subtle variations like which rocker arm arm goes with hydraulic valve push or AGR module. This OEM catalog shows the exact Volvo Penta part numbers for each component. You can order directly from any dealer without second-guessing. For general diesel engine knowledge, you can always hit up this Wikipedia article on diesel engines if you need background on how these systems work, but for part identification, stick with the factory source.

Audience: Who Needs This PDF

DIY mechanics tackling a head gasket job or top-end rebuild. Shop owners stocking correct parts for these common marine and industrial engines. Even a beginner can follow the exploded diagrams to identify what’s in front of them. But don’t confuse this Parts Catalog with a service manual. It tells you what to order, not how to install. You’ll still need the Volvo Penta workshop manual for torque sequences and clearances.

3 Critical Details from the Cylinder Head Section

First, the gasket thickness variance between the TAD650VE and TAD660VE — over a tenth of a millimeter difference can change compression ratio. Second, the glow plug part numbers: TAD650VE uses 20783049 (24V shown on the TAD660VE page). Third, the rocker arm assemblies differ; the TAD660VE lists a separate rocker arm for the hydraulic valve push AGR module. Small details, big consequences if you order wrong.

Frequently Asked Questions

Does this include torque specs?

No, this is a parts catalog only. For torque values you need the corresponding Volvo Penta service manual.

Can I rebuild the engine with just this catalog?

Not completely. The catalog gives you every part number — cylinder head, gaskets, valves, sleeves — but it doesn’t describe how to remove or install them. You’ll use this to order the right parts, then follow a workshop manual for the actual wrenching. 100 pages of precisely what you need to avoid ordering the wrong rocker arm or glow plug.

Every time I see a parts catalog that’s not OEM, I cringe. Save yourself the headache. Access the Factory Manual and get the real specs in your hands.
