Takeuchi TKB-101, TKB-101S Parts Catalog

I have pulled wrenches on enough equipment to tell you straight: a parts catalog without factory part numbers is a stack of paper napkins. You order a seal kit from a generic listing and get a bag of o-rings that don’t match because someone guessed the cross-section. This 36-page Takeuchi TKB-101, TKB-101S Parts Catalog is the real deal. Printed off OEM plates, scanned straight from the original binder. No reprints, no redrawn diagrams – just the factory exploded views and part numbers that match the casting codes on your breaker.

Twenty-eight years in the trade taught me that the difference between a job that stays fixed and one that comes back on a flatbed is the information you start with. This manual gives you the exact part numbers for every seal, chisel, bushing, and bracket. Page 5 lists the breaker parts for the TKB-101 – including the retaining pin, stop pin, and front head seal kit. If you’ve ever had a chisel seize because you swapped a random pin from a different model, you’ll appreciate having the OEM dimensions in hand.

Parts Breakdown: What This 36-Page Catalog Covers

The chapter titles tell you exactly what you’re getting. Breaker Parts List, Tool List – that covers the main assembly. Then separate sections for the Hydraulic Breaker & Top Mount Type Bracket Group (for TB025, TB025 Long Arm, TB030, TB035) and the Flange Type Bracket Parts List. If you’re working on a TKB-101S, there’s a dedicated Hydraulic Breaker-S Type section with its own parts list and tool list. The catalog also includes the Chisel, Seal Kit Ass’y Parts List (Option) and the Service Tool Gas Charger Ass’y (Nitrogen Charging Tool) (Option) – that nitrogen charging spec is critical. Charge pressure wrong, and the breaker loses impact energy or blows the accumulator diaphragm. Page numbers: I don’t need to list them all – the index is three thumb-tabs deep, but the charging tool assembly diagram is two pages from the back.

Does This Manual Include Torque Specs?

No. This is a parts catalog, not a service manual. It gives you the OEM part numbers and exploded views – think of it as the shopping list for a rebuild, not the rebuild instruction. You still need a separate repair manual for torque values on the cylinder head bolts or the bracket mounting bolts. But if you’re pulling a TKB-101 apart, you want this open on the bench so you know exactly which bearing spacer and which snap ring goes back in. Over the years I’ve seen guys lose a whole shift tracking down a wear plate because they ordered by memory instead of the part number. That failure mode ends here.

3 Reasons to Choose OEM Documentation

First, the diagrams match what you have – not a generic shape drawn by an illustrator who never touched a breaker. Second, the part numbers correspond to Takeuchi’s current supply chain. Your local dealer can cross-reference a TKB-101S chisel part number from this catalog and have it on the truck the next morning. Third, the safety warnings aren’t a photocopy of a photocopy. The first three pages of this manual are dedicated to PRIMARY SAFETY MATTERS TO BE OBSERVED – including minimum safe distance from power lines based on voltage (table on page 4). That’s not fluff; that’s liability prevention. If you’re running a shop in San Antonio with guys who speak three languages, you keep this manual in the cab for reference, just like the manufacturer says.

Nitrogen Gas Charging: What the Option Section Tells You

The Enclosure of Nitrogen Gas section is short but critical. The Service Tool Gas Charger Ass’y parts list includes the valve core, charging hose, and pressure gauge assembly (service tool part numbers provided). If you’re recharging the accumulator, you need the correct adapter and the genuine o-ring from the seal kit. I’ve seen aftermarket charging kits leak because the threads were off by half a turn. The OEM parts list gives you the exact Takeuchi part numbers – order those, not a universal kit from the auto parts store.

Who Needs This Catalog?

If you own a Takeuchi excavator with a TKB-101 or TKB-101S breaker – or you rent your machine out and need to source replacement parts fast – you need this PDF. It’s also for the independent mechanic who touches compact excavators and wants to stock the right seals and pins. A beginner home-garage type might not need a parts catalog for a hydraulic breaker, but if you’re that far into a repair, you’re past beginner territory. Get this manual, a set of snap-ring pliers, and a torque wrench that’s been calibrated in the last six months.

How do I know if I have a TKB-101 or a TKB-101S?

Look at the model plate on the breaker body. The S‑type has a different bracket and a different seal kit. This catalog covers both in separate sections.

Will this catalog help me rebuild the hydraulic cylinder on the breaker?

It gives you the part numbers for the cylinder seal kit and the tool list needed for disassembly. But for step‑by‑step instructions on removing the cylinder head and inspecting the piston, you need the Takeuchi TKB‑101/TKB‑101S Service Manual. A parts catalog shows what goes where – not how to take it apart safely. Use both.

You saw the original Takeuchi warning label on page 1: Operators and maintenance personnel must read this manual before operating or maintaining the breaker. That’s not a suggestion. If you’re wrenching on a breaker, get the right parts the first time. Access the Factory Manual now.
