Yanmar 4TNV106-GGE 2007 Parts Catalog

You’ve got a 4TNV106-GGE on the stand or in the machine, and you need a part. You don’t need a generic aftermarket list that guesses which bolt fits where. You need the original Yanmar parts catalog – the one that shows the cylinder block, the camshaft, the crankshaft, and every gasket in between. I’ve been turning wrenches since before some of you were born, and I’ve seen orders get screwed up because somebody used a third-party parts list. This 28-page OEM document from 2007 is the only source I trust for that engine.

Cylinder Block & Gear Housing: What’s in Sections 1 and 2

Section 1 covers the cylinder block assembly. You get the block itself, liner, piston cooling nozzles, and all the plugs. Section 2 is the gear housing – timing gear cover, oil pump drive, and the camshaft thrust plate. Each part has a reference number, a level indicator (1,2,3) showing if it’s a sub-component, and an interchangeability symbol. If the part changed mid-production, the catalog tells you which engine serial number range the new part applies to. Page 3 explains the symbols: N for not interchangeable, K for one-way interchange, and others. Don’t skip reading that page – it saves you returning a camshaft that won’t fit.

One thing I appreciate: the illustration numbers match the list reference numbers. You’re not playing “find the needle” like in some aftermarket diagrams. The 28 pages are tight – every page has a purpose.

Camshaft & Driving Gear: Assembly Breakdown from Section 7

Section 7 is labeled “Camshaft & Driving Gear.” It shows the camshaft itself (part number 129470-51040), the roller bearings, the retainer, and the gear. If you’re replacing a camshaft, you need to verify the bearing part numbers – the catalog lists two roller bearings (122710-51050) and a retainer (12947… the number cuts off in the OCR, but the page gives the full part). The level system tells you the bearing is a sub-component of the camshaft assembly. Order the bearing separate if you’re reusing the camshaft. That’s the kind of detail a parts catalog gives you that a generic list won’t.

Also worth noting: the catalog includes a “Remarks” column for each part. For the camshaft, there might be a note about interchangeable serial numbers. Always check the (A)-(F) columns – those correspond to engine serial number ranges. If your engine serial is outside the range, the part may not fit.

Crankshaft & Piston: Section 8 Exploded View

Section 8 covers the crankshaft and piston assembly. You get the crankshaft, main bearings, connecting rods, pistons, rings, and wrist pins. Each part has a level indicator. For example, the piston ring set is level 2 (sub-component of the piston). If you order a piston, you need to check whether the ring set is sold separately – this catalog tells you. The fuel injection pump (Section 12) and governor (Section 13) are also broken down the same way. I’ve seen guys rebuild a 4TNV106-GGE and forget the fuel injection valve (Section 14) shims. This catalog lists every shim and washer in the fuel line (Section 15).

Cooling system parts are in Section 11 – water pump, thermostat, hoses. The valve system shows up in the cylinder head section (Section 4) and the fuel injection valve section. You get part numbers for the valve springs, keepers, and guides. No guesswork.

3 Reasons to Choose OEM Documentation Over Aftermarket Lists

First, aftermarket catalogs often use generic part numbers that cross-reference wrong. I’ve had a customer bring in a water pump that was “compatible” but the bolt pattern was off by 2 mm. The Yanmar catalog gives you the exact OEM part number – you call the dealer, they punch it in, and it fits. Second, the interchangeability symbols tell you if a new part supersedes an old one and whether they can mix. Third, the level system lets you order just the sub-component you need instead of buying a whole assembly.

This catalog is from 2007, so it matches the original production run of the 4TNV106-GGE. The Ammann Yanmar B12 B17 Parts Catalog covers other engines in the same family. If you also work on YB series, check the Yanmar YB271, B27 1994 Parts Catalog – OEM Factory Specs or the Yanmar YB301 YB351 1991 Parts Catalog – 248 Pages OEM for older models.

Does This Catalog Include Torque Specs or Service Procedures?

No. This is a parts catalog, not a service manual. It tells you what parts go together, not how to install them. You won’t find torque values for head bolts or clearance specs for the camshaft. If you need repair instructions, you need the corresponding Yanmar service manual. But if you want to order the correct gasket for the valve cover or the right fuel line O-ring, this catalog is your only reliable source.

For background on how these engines are used in the Automotive Industry Overview, Yanmar builds industrial and agricultural engines. The 4TNV106 is a 4-cylinder diesel used in construction equipment, generators, and pumps. Understanding the Automotive Industry Overview helps, but this catalog is strictly about part numbers.

FAQ – Four Questions About This Parts Catalog

Can I use this catalog to order parts for a rebuild?

Yes, if you need every gasket, bearing, and piston. Section 18 is the gasket set – it lists all gaskets for the engine. You still need a service manual for assembly specs.

Does it cover the fuel injection pump and injectors?

Yes. Sections 12 through 15 cover the injection pump, governor, injection valve, and fuel lines. Part numbers include the pump assembly and individual components like delivery valves.

How do I read the interchangeability symbols?

Read page 3. N means the old and new parts are not interchangeable. K means the new part fits old but not vice versa. There’s also a symbol for parts that must be replaced as a set. Ignore these symbols and you might order a camshaft that doesn’t mate with your existing gear.

Is this the same as a service manual?

No.

This catalog is 28 pages of pure part-number data. It’s not a novel. You open it to find the part, you write down the number, you order it. That’s it. If you’re the kind of mechanic who wants to do the job once and not chase parts, you buy the OEM catalog. Ammann Yanmar B12 B17 Parts Catalog is also available if you work on that series.
