Takeuchi TB070 Parts Catalog

If you’ve ever ordered a part for a Takeuchi TB070 and got the wrong one because some aftermarket site listed a generic number, you know the frustration. I’ve seen guys pull a brand-new valve out of the box only to find it doesn’t match the porting because the serial number split wasn’t checked. This Parts Catalog is the factory document – 464 pages of exploded views, OEM part numbers, and exact serial number ranges. No shortcuts. No vague descriptions. You get the same data the dealer’s parts counter uses.

UNDERCARRIAGE: Crawler Belt and Track Roller Breakdown

Need a carrier roller or track adjuster? The catalog breaks the undercarriage into every major component: LOWER FRAME, CRAWLER BELT, CARRIER ROLLER, TRACK ROLLER, FRONT IDLER, TRACK ADJUSTER, TRAVEL DEVICE, SLEW BEARING, SWIVEL JOINT & ACCESSORIES (split by serial number 1703004~1703949 and 1703950~). That means you order the exact part for your machine’s build range. Page 2 of the manual shows how to read the parts list – pay attention to the compatibility codes (H/L) so you don’t mix up single-part swaps versus set swaps.

How This Parts Catalog Is Organized

The table of contents follows the physical layout of the machine. Each section covers a major assembly, and within that, sub-assemblies are listed with their own illustration and parts table. For example, the TURNTABLE & CONTROL LEVER section includes everything from the SLEWING DEVICE, BOOM SWING, SWING STOPPER, to the TRAVEL LEVER & PEDAL variants across multiple serial number breaks. If you’re working on a machine with serial number 1703076 to 1705080, you go to the correct sub-section. The book even includes OPERATION LEVER piping for multi-pattern and ISO-JCB pattern configurations.

HYDRAULIC PIPING & TANK: Valve Coverage and Serial Number Splits

One of the most critical sections for any TB070 owner is the HYDRAULIC PIPING & TANK. It covers GREASE PIPING, VALVE & ACCESSORIES (including versions with second auxiliary lines, split by 1703004~1704085 and 1704086~), EMERGENCY SHUT-OFF VALVE, PUMP DRIVE, HYDRAULIC TANK, and FUEL TANK & FUEL PIPING. If you’re replacing a valve, you need the correct part number for your machine’s configuration – the catalog shows the exploded view with the exact bolt torque and seal sizes (those specs are in the related workshop manual, but the part numbers here are the starting point).

For reference, you can pair this with the Takeuchi TB070 Parts Catalog (the same document) and the Takeuchi TB070 2000 Workshop Manual – Section: Vi. Engine for engine overhaul specs. The wiring diagrams and electrical system breakdowns are covered in the Takeuchi TB070 2000 Workshop Manual – Section: Engine.

Audience Fit: Who Needs to Own This

This is for anyone who owns or services a Takeuchi TB070 excavator. If you’re a DIY owner-operator doing your own undercarriage rebuilds or hydraulic repairs, this catalog keeps you from ordering the wrong part. If you run a shop that services compact excavators, you need this on the bench next to the workshop manual. The catalog covers every component from the ENGINE & ACCESSORIES (2/2) to the CAB (5/5) including the air conditioner, heater, and defroster. Even the decal section is broken down by language – English, German, French, Spanish, Italian – so you can order the correct safety labels.

Source Validity: OEM Factory Print, Not Aftermarket

This is a direct scan of the original Takeuchi parts catalog, book number PL1-101Z5, covering serial numbers 1703004 to 1705487. Aftermarket parts catalogs often combine multiple models or skip serial number splits. This document preserves every revision and compatibility note. The auto industry has learned the hard way that using generic listings leads to fits, leaks, and downtime. Automotive Industry Overview data shows that OEM documentation prevents costly errors. If you want to understand why serial number splits matter, check the Automotive Industry Overview for background on standardization.

Does this Parts Catalog include torque specs for hydraulic fittings?

No. This is a parts catalog – it gives part numbers, quantities, and compatibility. For torque values, you need the separate workshop manual.

Does the catalog cover the TB070 with the telescopic arm?

Yes. It includes specific sections for TELESCOPIC ARM, TELESCOPIC ARM KIT, and even a separate COUNTERWEIGHT section for telescopic arm machines. The counterweight for telescopic arm is listed under TURNTABLE & CONTROL LEVER.

What serial number range does this catalog cover?

Serial numbers 1703004 through 1705487. Every section references the specific serial number range it applies to – for example, SWIVEL JOINT & ACCESSORIES has two sub-sections: 1703004~1703949 and 1703950~.

Can I use this catalog to order a replacement valve for the second auxiliary lines?

Yes. The section VALVE & ACCESSORIES (with the second auxiliary lines) has three sub-sections: 1703004~1704085, and then 1/2 and 2/2 for 1704086~. You’ll find the exact part number and quantity for the valve body, spool, and related seals.
