Takeuchi TB025 2008 Parts Catalog – OEM Factory Parts Breakdown

You need a part for a TB025. You look up an online parts diagram. It’s wrong. Now you’ve got the wrong seal, the machine is down, and the customer is waiting. I’ve seen it a hundred times – a guy trusts a third-party parts lookup and ends up with a 20-minute job turned into a week of returns. That’s why Takeuchi TB025 2008 Parts Catalog is the only source I’ll put on my bench.

This is not a repair manual. It’s a 321-page OEM parts catalog published in 2008, covering serial numbers S/N1255001-1258249. Every exploded view, every part number, every quantity – straight from Takeuchi. No aftermarket guesswork. No reprints. You get the same book the dealer uses to order your parts, and if you’ve ever tried to cross-reference a Takeuchi bearing seal without this, you know exactly what I mean.

7 Major Sections in This Catalog

Open it and you’ll find these chapters, each with its own index and part number lists:

• 1 UNDERCARRIAGE – lower frame, track rollers, sprockets, idlers
• 2 TURNTABLE & CONTROL LEVER – swing circle, control valve assemblies
• 3 ENGINE & ELECTRICAL SYSTEM – starter, alternator, wiring harness parts
• 4 HYDRAULIC PIPING & TANK – hoses, fittings, reservoir components
• 5 COVER & CAB – sheet metal, glass, seat, floor mats
• 6 HOE ATTACHMENT – boom, arm, bucket cylinders and pins
• 10 ENGINE(3TN84L-RTBZ) & ENGINE(3TNE84-TBZ/TBY) – separate engine breakdowns
• 99 KITS, ATTACHMENTS & QUICK REFERENCE – special tool kits, optional attachments

Every section uses the same reference system you saw on page 1-3 of the lower frame: item number, part number, description, quantity, change code, serial number range, and service remarks. That’s the level of detail a pro needs to order one bolt and know it’s the right one.

Undercarriage and Lower Frame: Part Numbers You Can Trust

The OCR sample shows the lower frame breakdown. Item 1 is the frame itself – part number X 0351001100. Item 1-1 is a bracket, 0471000900. You see a slew bearing (item 10, 1913003600) with a separate seal (item 11, 1913003609). These are the parts that keep the machine rotating. Order the wrong bearing seal and you’re pulling the turntable again. With this catalog, you read the exploded view, match the serial number suffix, and write the order once.

Need a swivel joint? It’s item 17: 1904006400. The bolt kit around it is listed with exact lengths – M10 x 25, M10 x 65, washers and spring washers. I’ve watched techs waste half a day trying to match a bolt by eyeball. This catalog ends that.

Does This Cover the Engine Electrical System?

Yes. Chapter 3 covers ENGINE & ELECTRICAL SYSTEM. But note: this is parts only. You get the alternator, starter, glow plugs, and wiring harness with part numbers and quantities. You don’t get wiring diagrams or diagnostic procedures. For that you need the separate service manual. What this catalog gives you is the ability to order the correct starter for your engine variant – either the 3TN84L-RTBZ or the 3TNE84-TBZ/TBY. Those two engines have different part numbers, and this catalog shows both in chapter 10.

Source Validity: OEM vs Aftermarket

I’ve had aftermarket parts catalogs that listed a fuel filter for a TB025 that was actually for a TL26. Cross-references that didn’t cross. This is a factory Takeuchi document, published January 24, 2008. The part numbers match what the dealer’s system shows. If you’re ordering from Takeuchi, this is the bible. If you’re using aftermarket parts, you still need the OEM part number to cross-reference correctly. Skipping that step means returns, downtime, and lost money. I’ve seen it happen on machines that paid for themselves three years ago – don’t be that guy.

Related manuals you might need: Takeuchi TB025 Parts Catalog (this one), Takeuchi TL26 Parts Catalog – 288 Page OEM Factory Manual, and Takeuchi TL150 Parts Catalog – 599-Page OEM Exploded Views. Each one covers a different machine family but the same factory rigor.

Hydraulic Piping: Cross-Reference Data

Chapter 4 (HYDRAULIC PIPING & TANK) is one of the most used sections in our shop. Every hose assembly has its own part number, and each one includes the fitting codes. No guessing whether a -8 ORFS or -10 JIC fitting is on that line. The exploded view shows the routing, and the parts list gives the quantities. If you’re replacing all the hoses on a high-hour TB025, this catalog lets you order every one at once. That’s real time saved.

FAQ – Takeuchi TB025 2008 Parts Catalog

Is this a repair manual with torque specs?

No. This is a parts catalog. It gives you part numbers, exploded views, and quantities. Torque specs and service procedures are in the separate service manual.

Does it cover both engine variants (3TN84L-RTBZ and 3TNE84-TBZ/TBY)?

Yes. Chapter 10 has separate sections for each engine. Make sure you check your serial number and engine plate before ordering.

How do I read the reference page like page 1-3 in the lower frame section?

Each exploded view has a reference number (e.g., E3-01a-4-D). The parts list below it gives item numbers, part numbers, and quantities. The serial number column tells you if a part changed mid-production. Always verify your serial range.

Can I use this to rebuild the hoe attachment?

Absolutely. Chapter 6 (HOE ATTACHMENT) has all the pins, bushings, cylinders, and seals. You’ll see the bucket linkage with every cotter pin and spacer. Order the complete rebuild kit by looking up the kit number in chapter 99, or piece it together from the individual item numbers. Either way, this catalog is required to do it right.

You’ve got a Takeuchi TB025 that needs parts. You can spend hours on generic parts sites hoping the dimensions match, or you can open this 321-page catalog, find the exact part number from the factory, and order it once. That’s the difference between a job that pays and a job that sucks your shop dry. Access the Factory Manual from AutoRepairManuals and get back to wrenching.
