Takeuchi TB138FR Parts Catalog – 349 Pages OEM Exploded Views

Description

Let me tell you something. I’ve been wrenching on equipment for 28 years, and the single biggest time-waster in any shop is ordering the wrong part. You get a hydraulic hose that’s two inches short, or a seal kit that doesn’t match your machine’s serial number. That’s not a parts problem – that’s a documentation problem. The Takeuchi TB138FR Parts Catalog is the factory source. 349 pages of exploded diagrams and genuine part numbers. No guesswork.

Half the aftermarket parts lists I’ve seen are copied from some PDF that was scanned sideways. You order a track roller from those, and it’s the wrong offset. This catalog comes from Takeuchi directly – the same one their dealers use. It covers TB138FR serial numbers from 13810003 onward. Page 1 confirms the exact serial range.

Takeuchi TB138FR Parts Catalog: The Only Part Number Source You Should Trust

Opening this catalog gives you eight major sections: Undercarriage, Turntable & Control Lever, Engine & Electrical System, Hydraulic Piping & Tank, Cover & Cab, Hoe Attachment, Decal & Tool, and Hydraulic Device. Each section breaks down into subassemblies like Boom Offset (1/2) and (2/2), Travel Motor reduction and motor sections, and even the ISO-JCB pattern piping. If you need a boom cylinder seal kit, you flip to Chapter 8 – Hydraulic Device – and find the exact cylinder breakdown with part numbers for each O-ring and wiper seal.

8 Major System Sections in This Parts Catalog

Here’s what you get:

• Undercarriage – crawler belt, carrier roller, track adjuster, slew bearing
• Turntable & Control Lever – boom offset, travel lever, operation lever with ISO-JCB piping
• Engine & Electrical – engine accessories, air cleaner, decel unit, security system, radio
• Hydraulic Piping & Tank – valves, accumulator, boom emergency shut-off, pump drive, fuel tank
• Cover & Cab – floor frame, seat, cab sections 1-7, heater, air conditioner
• Hoe Attachment – boom, arm, bucket, auxiliary line, 2nd auxiliary line
• Decal & Tool – decals for cab and canopy, tool list, painted color codes
• Hydraulic Device – swivel joint, control valve, block assy No.1-12, solenoid valves, cylinders, travel motor, slew motor, hydraulic pump

That’s the whole machine, broken down into factory exploded views.

Undercarriage and Travel Assembly Breakdown

Need a new track adjuster? Chapter 1 shows you the idler, travel device, and all the hardware. Page 5 of the manual explains how to read the parts list – compatibility letters, serial number applications, and quantities per assembly. I’ve seen guys order two track rollers when they only needed one because the aftermarket catalog listed a set number that didn’t match. The factory catalog gives you the exact count per machine.

How to Read the Parts Manual

Take a minute to read the instructions on page 5. Seriously. Each part gets a number, a description, a quantity, and a compatibility code. If there’s an asterisk (*), it means the item is an assembly and not sold separately. A double asterisk (★) means it’s a component of that assembly. The legend also shows supersessions – (H) means the upper line part replaces the lower, (L) means the lower replaces the upper. That saves you from buying NOS parts that have been updated. If you are working on any complex machine, understanding these codes prevents returns and downtime.

Why OEM Documentation Matters

Aftermarket catalogs often skip details like the block assy No.6 and No.7 in the hydraulic device section, or the exact solenoid valve configuration for the air conditioner. This catalog lists every block, every pilot valve (left and right with 2nd auxiliary lines), and every proportional valve. It also includes handle assemblies with slide switches and three switches. If you are retrofitting a second auxiliary line, the piping sections show both standard and proportional control layouts. That level of detail is why I refuse to use anything that isn’t factory. The Takeuchi TB138FR Workshop Manual – Section: Moteur covers engine removal, but you need the parts catalog for ordering the gaskets. Pair it with the Takeuchi TB138FR Workshop Manual – Section: Vi. Engine for troubleshooting. The Takeuchi TB138FR Workshop Manual is a separate purchase but complements this catalog for a complete shop setup.

For background on why standardized documentation matters across the industry, see Automotive Industry Overview. The same principles apply to construction equipment – consistency in part numbering prevents millions in misorders annually. Automotive Industry Overview further explains.

A short note: this catalog is a parts list, not a service manual. It won’t tell you torque values or procedure steps. But if you need the correct part number for a TB138FR, this is it.

Does this catalog include service procedures or torque specs?

No. This is a parts catalog only, for ordering genuine components.

How do I identify the correct part number for my TB138FR?

First, locate your machine’s serial number – this catalog covers S/N 13810003 and up. Then find the appropriate section in the table of contents. For example, if you need a boom cylinder seal, go to Chapter 8, find “Boom Cylinder” in the list, and look for the exploded view. Each part has a callout number and a corresponding part number in the table. The manual also includes a numerical index at the back, so you can look up a part number you already have and find where it fits. This is the same system Takeuchi dealerships use daily.

If you’ve been wasting time cross-referencing aftermarket catalogs or scraping part numbers off old seals, stop. Get the factory source. This catalog sits on my reference shelf, tabbed for the sections I hit most – the control valve blocks and the travel motor. Access the Factory Manual and you’ll have the same information the dealer’s parts counter has.
