Takeuchi TB68S Parts Catalog – 96 Pages of Factory Exploded Parts

Spent an afternoon chasing a part number from a generic catalog? Pulled a gasket that didn’t match because some cross-reference site guessed wrong? I’ve been there. The Takeuchi TB68S Parts Catalog kills that waste. This is the same 96-page binder the dealership parts counter uses. It lists every nut, seal, and gasket for the TB68S loader equipped with the SD334 diesel engine. Page 4 shows the entire engine overhaul kit – 23 items with Takeuchi part numbers. Page 5 gives you the quantity per section so you know if you need one seal or twelve. That kind of specific data keeps your job from turning into a second trip to the parts store.

Overhaul Kit-Engine: The Most Useful Page in This Catalog

Flip to Figure E100A on page 4. You get an exploded illustration of the SD334 engine overhaul kit. Key numbers 1 through 23 – each one tagged with the product code, part number, and quantity. The mark in the key number column tells you which parts belong to which assembly. If you’re rebuilding the top end, you can order gaskets for the cylinder head (key 3 and 4), the seal washer (key 5), and the stem seal for the valve mechanism (key 6) without guessing a single digit. That’s not theory – that’s the factory parts list.

7 Systems Covered by the TB68S Parts Breakdown

This catalog organizes every replaceable component into seven logical groups – engine, fuel system, cooling, exhaust, lubrication, water pump, and oil cooler. The fuel system section alone lists the injection pump gasket (key 18), the fuel piping gaskets (key 7 and 23), and the filter gasket (key 15). Each part appears on the exploded diagram first, then in the parts list with the identical key number. You don’t flip back and forth trying to match a blurry thumbnail – the drawing and the table sit on facing pages.

Does This Parts Catalog Cover the SD334 Diesel Engine?

Yes. The title page calls out “LOADED ENGINE / DIESEL ENGINE / MODEL SD334” before anything else. That engine is a Nissan Diesel unit, and the catalog includes the overhaul kit, the oil pan gasket set, the front cover seal, and the exhaust manifold gasket. If you’re working on a TB68S with a different engine – stop. This manual fits only the SD334 combination. The part numbers printed in Japan come straight from the manufacturer, not from a third-party transcriber.

Why OEM Part Numbers Beat Aftermarket Cross-References

Aftermarket “equivalent” databases reuse numbers from old paper catalogs without verifying the supersession history. One wrong digit and you get a water pump gasket that doesn’t match the cooling passage. This catalog prints the Takeuchi-verified numbers: K 10101-39225 for the bearing cap seal, K 11044-C8000 for the cylinder head gasket, K 15266-76200 for the head washer seal. Each number ties back to an OEM drawing. If you need to cross-reference later, you start from the truth. Start from a guess and you waste an hour on a return counter. You can also check the Automotive Industry Overview for more context on why OEM documentation matters in heavy equipment repair.

Get the Right Gasket Kit Without Taking the Engine Apart Twice

You’re pulling the oil pan – page 5 shows gasket key 8, washer key 9, and gasket key 10. That’s three separate parts. Buying a “universal oil pan gasket” almost always leaves you with the wrong thickness or missing the seal washer. Order the exact Takeuchi numbers: K 11121-C7800, K 11026-61000, and K 15066-90007. Or buy the whole overhaul kit (key numbers 1-23) and have every gasket, seal, and ring in one box. The mark column tells you which parts are included in that kit – marked with an asterisk. That kind of precision saves you from opening the engine twice because a valve stem seal was backordered.

Is this parts catalog specific to just the TB68S model?

Yes. It covers only the TB68S loader with the SD334 diesel engine.

How do I use the exploded view to order parts without mistakes?

Each diagram has key numbers that match a table on the same page or the facing page. Write down the part number from the table – do not rely on the illustration alone because some similar-looking gaskets have different numbers. For example, the oil cooler gasket appears twice as key 21 and key 22 with different part numbers. If you order one when you need two, the cooler will leak. The page headings also tell you the figure number (e.g., FIG. E100A) so you can reference the correct assembly. Cross-check the quantity column – one cylinder head gasket versus twelve stem seals – to confirm you’re reading the right row. Then order directly from the Takeuchi part number printed in the catalog. This method has never sent me the wrong part.

If you’re tired of playing detective with part numbers, get the OEM source. Access the Factory Manual and put the real Takeuchi parts data on your bench. Your next oil pan gasket will fit the first time.
