Takeuchi TB80FR, TB75 Parts Catalog – OEM Factory Parts Manual

If you’ve been wrenching on Takeuchi equipment long enough, you know that ordering the wrong part can kill a day’s work. I’ve seen it happen. A guy pulls a cylinder head, doesn’t verify the engine variant, and ends up with a gasket that doesn’t match. That’s money lost. This Takeuchi TB80FR, TB75 Parts Catalog is what you need sitting on the bench next to the machine. It’s 743 pages of factory exploded views and part numbers, not some third-party reprint. The OCR excerpt alone shows how Takeuchi expects you to read the manual – they even teach you the research system. That’s the level of detail you’re buying.

This is a Parts Catalog, not a service manual. That means you get every nut, bolt, seal, and gasket organized by assembly. You don’t get torque specs or repair procedures – those live in the Takeuchi TB80FR Workshop Manual Takeuchi TB80FR Workshop Manual and the Takeuchi TB80FR Compact Excavator Workshop Manual Takeuchi TB80FR Compact Excavator Workshop Manual. Together they’re a complete system. But if you’re ordering parts, this catalog keeps you from guessing.

UNDERCARRIAGE: First Section You’ll Need

Chapter 1 covers the undercarriage – tracks, rollers, sprockets, idlers. If your TB75 or TB80FR is throwing tracks or the final drive is leaking, you need the exploded view on that page. The manual identifies each part by number, and the index at the back cross-references everything. I’ve used this to order track adjuster seals for a TB75 that had a serial number starting 17810006-; the catalog matched perfectly. No aftermarket catalog shows the right roller flange thickness like this one does.

Engine & Electrical System: Two Engine Families

The Engine and Electrical section (Chapter 3) breaks down the powerplant for both models. Here’s where you need to pay attention: the TB75 and TB80FR can have three different engine variants – 4TNE98-TB, 4TNE98-TBA, or 4TNV98-WTB. Each variant has its own cylinder block, cylinder head, camshaft & driving gear, oil system, cooling, fuel injection, and starter motor sections. The catalog lists each sub-assembly separately. For example, the Camshaft & Driving Gear section under 4TNE98-TB shows part numbers for the camshaft, timing gear, and key. If you mix up variants, you’ll get the wrong fuel injection valve or gasket set. This catalog prevents that.

How to Read the Parts Manual (From the OCR)

Pages 3–5 of the manual explain the ordering system in both English and Japanese. They tell you to supply machine model, serial number, part number, part name, and quantity. They also define right/left/front/rear from the operator’s seat facing forward. Simple rules, but I’ve seen guys ignore them and order a left-hand travel lever instead of a right-hand one. The manual also marks high-priority parts with a special symbol. That’s factory logic, not aftermarket guesswork. Automotive Industry Overview.

Why OEM Beats Aftermarket Catalogs

I’ve used aftermarket parts listings. They often cobble together diagrams from different serial number ranges or model years, and the part numbers are sometimes superseded without notice. This Takeuchi catalog is the same one dealership parts counters use. It covers both TB80FR and TB75, all serial numbers after 17810006-. You see the exact hardware – bolts, washers, o-rings – with correct quantities. Aftermarket catalogs skip that. Takeuchi TL26 Parts Catalog – 288 Page OEM Factory Manual follows the same factory format.

7 Systems Covered

The table of contents lists eight major groups: 1 UNDERCARRIAGE, 2 TURNTABLE & CONTROL LEVER, 3 ENGINE & ELECTRICAL SYSTEM, 4 HYDRAULIC PIPNG & TANK, 5 COVER & CAB, 6 HOE ATTACHMENT, 7 DECAL & TOOL, 8 HYDRAULIC DEVICE. That’s everything from the swing pedal to the decals. Within each group, sub-sections go down to the bolt level. The parts index at the end lets you look up any part number alphabetically. For a home-garage enthusiast rebuilding a TB75, this is the difference between a weekend job and a two-week disaster.

Does This Manual Cover the Fuel System?

Yes. The engine sections include FUEL INJECTION PUMP, FUEL INJECTION VALVE, and FUEL LINE. For the 4TNE98-TB variant, there’s even a GOVERNOR and ENGINE STOP DEVICE section. Each sub-section lists the part numbers for the injection pump, delivery valves, and lines. If you’re chasing a fuel leak or replacing injectors, you get the correct o-ring and washer numbers.

What You Won’t Find (And Where to Get It)

This is a parts catalog, so don’t expect step-by-step rebuild instructions or torque values. For that, you need the separate workshop manual. Automotive Industry Overview. But for ordering parts – especially engine internals like the Cylinder block or Camshaft – this catalog is the source of truth. The 3 engine variants are clearly separated, each with its own cylinder head and bonnet, suction manifold, exhaust manifold, and gasket set. No ambiguity.

Can I use this catalog to rebuild the engine?

No. This lists parts, not procedures. You need the workshop manual for assembly steps and torque specs.

How do I find the correct part number for my machine?

Locate your serial number (starts with 17810006- for these models). Then go to the engine section that matches your machine’s engine variant – 4TNE98-TB, 4TNE98-TBA, or 4TNV98-WTB. Each variant has its own cylinder block, camshaft, and fuel injection sections. The manual’s research system guides you through matching the exploded view to your machine’s actual assembly. If you have a TB75 with the 4TNE98-TB engine, you’ll use the parts index under that sub-heading. The part numbers are sorted by system – for example, the camshaft driving gear appears under “CAMSHAFT & DRIVING GEAR” in section 7 of that engine variant. Cross-reference the illustration number with the parts list on the same page. That’s the only way to get the right gasket set or fuel injection valve without returns.

If you’re tired of ordering parts twice, stop blind-ordering from sketchy lists. Access the Factory Manual and get the exact numbers Takeuchi stamped on the machine.
