Takeuchi TB25, 250 Parts Catalog – 230 Pages of OEM Exploded Views

I’ve lost count of how many times a job gets held up because somebody ordered the wrong hose or a bracket that doesn’t line up. You pull the old part, you measure it, you guess at the number – and then the bin shows up with something that looks close but ain’t. That’s where a factory Takeuchi TB25, 250 Parts Catalog stops the guesswork cold. This isn’t a reprint or a third-party compilation. It’s the actual OEM publication Takeuchi put together for their compact excavators. 230 pages, every part number tied to an exploded view. You need the control box gasket? You find it in the illustration, you read the part number, you order it. Done.

Look, I’ve torqued head bolts on everything from a Honda Civic to a Cat D6. When you’re working on a TB25 or a 250, the difference between a part that fits and one that doesn’t is often a single digit in the part number. This catalog gives you those digits straight from the factory. No cross-referencing, no calling the dealer and hoping the kid on the phone knows his stuff. Open the PDF, find the group, get the number, place the order. That’s it.

Exploded Views: What You Get on Each Page

Page 3 of this catalog explains the layout – and it’s dead simple. Upper half of the leaf holds the exploded view of the parts in the order they’d be assembled. Lower half has the list. The front/rear and right/left orientation is based on the operator’s seat perspective for the upper machinery, and the dozer blade side for the lower. That matters when you’re underneath and trying to figure out which bracket holds the travel motor. The manual even tells you that the control box and hydraulic devices are shown separately – no cramming everything into one confusing drawing.

Each illustration uses an item number that links to the part list. If you see a “0 *” next to an item, that means it’s an assembly – the sub-parts are listed below. No guessing which o-ring goes inside the accumulator. It’s right there.

Parts List Decoded: Item, Part Number, Description, Quantity

Flip to page 4 and you’ll find a sample entry. Item 0-1 is “CONTROL ASSY, engine” with part number 05441-90000. Then sub-parts like O-RING 140×3.0 (part 19000-16499). The description column uses a “**” prefix for sub-parts under an assembly. You also get a remarks column for serial number ranges. If you’ve got a TB25 with serial number 2305, you need the hose part 19081-09095 – same page tells you that. That’s the kind of detail that keeps you from buying a fuel line that’s two inches too short.

Part numbers that aren’t for sale have an “X” prefix. That’s rare, but good to know so you don’t waste a week waiting for something you can’t order.

Does This Manual Cover the TB25 and 250 Versions?

Yes – the catalog title says “TB25/250” and the example on page 3 lists both model numbers. But pay attention to the serial number column. Some parts changed between production runs. The catalog includes a “Serial No.” column in the parts list so you can match the right revision to your machine. If you’ve got a 250 built after a certain break point, the travel motor seal might be a different compound. You’ll see it in the remarks.

3 Reasons to Use an OEM Parts Catalog Instead of Aftermarket Lists

First, the drawings are factory-original. Aftermarket catalogs often use generic silhouettes or skip hardware like washers and caps. OEM shows every bolt, every clip, every o-ring. Second, the part numbers are verified against Takeuchi’s own database. I’ve seen aftermarket sites list a part number that was superseded five years ago – you order it and it’s backordered. Third, the exploded view order follows the actual assembly sequence. That helps you visualize how things come apart. You don’t get that from a plain parts list.

Don’t waste time with pirated PDFs that have missing pages or watermarks covering the illustrations. This is a clean scan of the original publication. 230 pages, no gaps.

How to Order Parts the Right Way – What You Must Include

Page 3 spells it out: when you order, state the model (TB-25 or 250), the machine serial number, the part number, the description, and the quantity. Example given: TB-25, serial 2305, part 19081-09095, hose, 2 pcs. Simple. If you skip the serial number, the dealer might send the wrong revision. If you skip the part number, you’ll get a blank stare. The catalog gives you all that data in one place. Print the page, circle the part, hand it to the parts counter.

Can I use this parts catalog to find the correct bolt torque for the swing motor?

No. This is a parts catalog, not a service manual. It shows part numbers and exploded views for ordering. Torque specs are in the service manual, which we also carry.

Why is the page layout half drawing, half list? Is that standard for Takeuchi?

Yes, that’s how Takeuchi prints their parts catalogs. The upper half is the exploded view showing the order of assembly. The lower half is the part list with item numbers, part numbers, descriptions, quantities, and serial number notes. This layout keeps you from flipping back and forth. On page 3 they explain that the control box, engine control, bucket, and hydraulic devices are drawn separately because they’re too detailed to fit. That’s standard for the TB25 and 250 lines. You’ll learn to read it in five minutes, and after that you’ll wonder why every manufacturer doesn’t do it this way. The exploded view orientation matches the machine as you’d see it from the operator’s seat – front, rear, right, left. For the lower machinery, front is the dozer blade side. That consistency helps when you’re under the machine and trying to match a bracket to the drawing. I’ve used these catalogs on dozens of compact excavators, and the time saved on ordering alone pays for the manual the first job.
