Takeuchi TB800 Parts Catalog – 188 Pages of Factory Part Numbers

You know the drill. You pull a part off a TB800, the number’s worn off, and the aftermarket parts lookup gives you three options with no way to tell which is correct. That wasted time turns a quick repair into a lost afternoon. Mike Callahan here. I’ve been turning wrenches since before some of you were born, and I’ve seen more wrong parts pulled from boxes than right ones. This factory Takeuchi TB800 Parts Catalog is what you need on the bench. It’s 188 pages of exploded illustrations and OEM part numbers—no aftermarket reinterpretation, no Chinese knock-off listings. You get the exact number Takeuchi stamped on the part.

Parts Breakdown for the TB800 Engine – What the Catalog Includes

The TB800 uses a Yanmar 3T72L-TB engine rated at 17 HP at 2400 rpm, with a bore x stroke of 2.83 in. x 2.83 in. and 914 cc displacement. The catalog breaks down the engine into every subassembly: cylinder head, piston & rod, fuel injection pump, and cooling system. Each exploded view has numbered callouts linked to a parts list with factory part numbers, quantities, and illustrations that match what you see on the machine. You won’t find generic descriptions like “seal kit” without telling you which specific O-rings are inside.

Know your part number before you pick up the phone.

188 Pages of Factory Parts Indexing – No Aftermarket Guesswork

This is not a scanned copy of a third-party translation. It’s the official Takeuchi publication, printed with the same layout the dealership uses. 188 pages of tightly indexed sections covering the engine, undercarriage, hydraulics, electrical, and attachment groups. The spec page in the front gives you the full machine weight (4366 lbs), ground pressure (0.24 lb/sq.in.), and track dimensions. That’s the sort of baseline data you need when ordering wear parts like track chains and sprockets.

Does This Catalog Include Torque Specs?

No. This is a parts catalog, not a service manual. If you need torque values for head bolts or hydraulic fitting threads, you need the factory service manual. But for identifying which bolt goes where and what the factory part number is, this catalog is your answer. For example, the hydraulic system section lists the gear pump with a discharge capacity of 5.97 gal/min per pump and a maximum relief pressure of 1995 p.s.i. The catalog gives you the part number for the pump assembly, the seal kit, and the mounting hardware. Pair it with a service manual for specific torque specs.

Check the Part Number Before You Call the Dealer

Every shop that works on compact excavators knows the frustration of calling the parts counter with a description: “I need the seal for the boom cylinder.” The counter person needs a part number, and without this catalog you’re stuck guessing. The TB800 Parts Catalog lets you find the exact section, locate the exploded diagram for your cylinder, read the part number, and hand it to the dealer. That call drops from fifteen minutes to thirty seconds. The same applies for track rollers, hydraulic hoses, and electrical switches.

Undercarriage and Hydraulics: Identifying Wear Parts

The undercarriage section covers everything from the roller frames to the track shoes. The TB800 runs a blade width of 55 in. and rail length 129 in. when transported. The catalog lists each sprocket tooth profile, idler dimensions, and track chain pitch. On the hydraulic side, the gear pump exploded view shows the drive shaft, bearings, and seal package. If you’re chasing a leak in the travel motor, you can find the exact seal part number without pulling the whole assembly apart to measure.

If you work on other Takeuchi compact excavators, the Takeuchi TL26 Parts Catalog – 288 Page OEM Factory Manual follows the same format. For larger models, the Takeuchi TL150 Parts Catalog – 599-Page OEM Exploded Views covers the TL150. Also check the Takeuchi TL140 Parts Catalog – 457 Pages of OEM Parts Indexing.

Can I use this catalog to rebuild my TB800 engine?

No, this is a parts catalog only. You need the service manual for procedures.

How do I find the part number for the hydraulic pump seal kit?

Open the catalog to the Hydraulic System section. Look for the pump exploded view. Each component is numbered with a callout that corresponds to a parts list. The seal kit is typically listed as a separate item with its own part number, not as individual seals. If you have the pump serial number, cross-reference it with the model year of your TB800. The catalog covers all variations of the TB800 produced. If you don’t see your specific pump, check the appendix for year-specific updates. The part number for the seal kit will be a seven- or eight-digit code. Write it down and order from your dealer. Do not use aftermarket seal kits unless you verify dimensions; this catalog uses factory specs for reference.
