TB TB108 1997 Parts Catalog – OEM Factory Specs for 2TNE68-ETBA Engine

I’ve torqued more head bolts than most people have had hot meals. And nothing burns my time faster than a wrong part number. If you’re working on a TB TB108 1997 Parts Catalog for the 2TNE68-ETBA diesel, you need the factory listing. Aftermarket catalogs skip sub‑assembly details, swap reference numbers, and leave you holding a gasket that doesn’t seat. This 46‑page OEM booklet cuts that crap out.

Cylinder Block, Gear Housing, and Flywheel Housing – What the Catalog Covers

Section 1 dives into the cylinder block – every bolt, sleeve, and plug that seals that engine. Gear housing (Section 2) and flywheel housing with oil sump (Section 3) follow. I’ve seen shops order a flywheel housing gasket from a third‑party list and miss the oil return hole alignment because the aftermarket drawing was generic. This catalog shows you the exact part count, including the separate oil sump gasket set. No guesswork on which gasket overlaps which seal.

Camshaft & Crankshaft: Factory Part Numbers in Sections 7 and 8

Section 7 covers the camshaft and driving gear assembly. Section 8 handles the crankshaft and piston group. Each reference number ties to an exploded diagram. You get the part code, quantity per engine variant (A through F columns), and compatibility symbols like K, Q, or O. If you’re replacing a camshaft gear on a TB108, you want the right tooth count – page 1 lists the interchange rules for the fuel injection pump gear as well. Cross‑reference before you order.

17 Sections in 46 Pages – Part Indexing for the 2TNE68-ETBA

From cylinder head and bonnet (Section 4) to suction manifold and air cleaner (Section 5), exhaust manifold (Section 6), lub.oil system (Section 9), cooling water system (Section 10), fuel injection pump (Section 11), governor (Section 12), fuel injection valve (Section 13), fuel filter (Section 14), starting motor (Section 15), generator (Section 16), and the tool and gasket set (Section 17) – every piece is indexed. The parts index at the back lets you find any component by name or reference number. For example, the fuel injection pump assy (part number 129040-51060) shows up in multiple configurations, and the catalog tells you which boost compensator version applies. No aftermarket list does that.

Who Needs a 1997 Parts Catalog for a TB108?

If you own or service equipment powered by the TB108 2TNE68‑ETBA – irrigation pumps, generators, small tractors – you need this. I’ve had home‑garage guys call me after ordering a “universal” fuel filter that didn’t thread onto the injection pump. This catalog lists the exact fuel filter assembly and its gasket. For professional shops, having the OEM interchange codes (N for new‑compatible, Q for incompatible) saves a return trip. See this Wikipedia article on diesel engines for a general overview of the platform, but for part numbers you stay here.

Match OEM Part Numbers – No Aftermarket Guessing

The difference between this 1997 factory print and a generic parts list is the implementation number column. When a part is superseded, the catalog shows the engine serial number range (E/#) where the change happened. For example, the boost compensator was optional up to engine E/#00155 for certain models – you’ll see that note in the fuel injection pump section. Aftermarket catalogs drop that detail. You end up with a part that fits half the engines. That’s not a “saving” – that’s a comeback.

Each one follows the same factory format – no shortcuts.

Frequently Asked Questions

Does this catalog include torque specs for assembly?

No. This is a parts catalog, not a service manual. It lists part numbers, quantities, and interchange codes. For torque values, you need the factory service manual for the 2TNE68 engine.

Can I use this to order parts for a different TB engine like the 4TNE88?

No. The TB108 and 4TNE88 share some platform architecture but have different cylinder bore, piston rings, and fuel injection components. Using this catalog for a different engine will give you wrong part codes. Stick to the engine model stamped on the block – TB108 2TNE68‑ETBA only.
