Takeuchi TB250 Parts Catalog – 515-Page OEM Factory Breakdown

I’ve seen guys order a swing pedal assembly three times because the aftermarket parts list had the wrong supersession chain. That’s a full day of downtime and a pissed-off customer. The Takeuchi TB250 Parts Catalog from AutoRepairManuals is the factory original – the same binder that sits in the dealer parts department. It kills the guesswork dead.

How to Read This Parts Catalog – It Matters

The first few pages of the manual explain the symbols and compatibility codes. You see a ★ before a part name? That means it’s a sub-assembly. You see (H) or (L) next to a part number? That tells you which direction the interchange works. Ignore those markings and you’ll order a part that doesn’t fit your serial number range. The manual uses the operator’s seating position to define left/right – I’ve had guys flip it because they were looking from the front of the machine. Read the “How to read the parts manual” section before you flip a single page. It’s on pages 2-5, and it will save you a restocking fee.

515 Pages – What You Actually Get

515 pages of exploded view diagrams, part numbers, and quantity tables. Every bolt, seal, hose, and hydraulic component for the TB250 mini excavator (serial number 125000001 and up) is broken down. The catalog covers the entire machine: undercarriage, boom, arm, bucket, engine, hydraulics, travel motor, swing mechanism, cab, electrical, and hardware. Each assembly has its own section with a clear index. Need a part number for the travel lever? It’s in the “TRAVEL LEVER & SWING PEDAL” section. The page numbering uses a Ref. 0-1 system – don’t let that throw you; it’s consistent across all factory Takeuchi manuals.

Who Needs This Manual? (Don’t Skip This)

If you own a TB250, run a fleet of them, or you’re the mechanic who has to keep them running – you need this. A parts catalog isn’t a repair manual; it’s the part-number bible. Pair it with the Takeuchi TB250 Workshop Manual for torque specs and procedures. If you’re a home-garage DIY guy who bought a used mini excavator, this catalog will stop you from ordering the wrong hydraulic hose three times. I’ve been there – don’t be that guy.

Source Validity: OEM vs Aftermarket Lists

Aftermarket parts catalogs are a disease. They copy old numbers, skip supersessions, and use generic illustrations. This is the original Takeuchi factory Parts Catalog – the same PDF the dealer uses. It includes the machine model, serial number range, and revision numbers on every page. You can see revision marks on the page footer – that’s how you know you’re looking at the current release. Never trust a third-party parts list for a TB250. Stick with the factory source. For a deeper look at how OEM documentation sets the standard in the industry, check out Automotive Industry Overview.

Ordering Parts Correctly – A Real-World Use Case

Say your TB250’s travel lever assembly is sloppy. You pull up the catalog, go to the index, find “TRAVEL LEVER & SWING PEDAL” (reference range 17510603-17512009). The exploded diagram shows each component labeled with a symbol. You match your serial number, find the part number for the lever boot, check the quantity (1 per machine), and see if there’s a supersession. Order that part number. Done. No return, no cross-referencing four different websites. That’s the value of 515 pages of factory data. Also check the Takeuchi TL26 Parts Catalog – 288 Page OEM Factory Manual if you work on the TL26 as well – same layout, same reliability.

If you need the operator’s instructions for the TB250 or its siblings, get the Takeuchi TB235 TB228 TB250 Operators Manual – Factory Specs – it covers daily operation and maintenance intervals.

Frequently Asked Questions

Does this parts catalog include torque specs?

No. This is a Parts Catalog – it only lists part numbers, diagrams, and quantities. You need the separate Workshop Manual for torque values and repair procedures.

Can I use this to rebuild my TB250 engine?

You can use it to identify every part you’ll need – pistons, rings, gaskets, bearings, seals. But the catalog won’t tell you the assembly order or clearances. For a rebuild, you absolutely need the Workshop Manual alongside this catalog. I’ve seen guys try to assemble an engine from a parts diagram alone – it ends with metal shavings and a core charge. Don’t do it. Get both. The parts catalog ensures you order the correct components; the workshop manual tells you how to put them together. That combination is the only professional way.

Aftermarket parts lists are a gamble. This Takeuchi TB250 Parts Catalog is the factory deal – 515 pages, OEM diagrams, no shortcuts. Automotive Industry Overview might be broad, but when you’re under a machine with a busted travel motor, you need a part number you can trust.
