Takeuchi TKB-801, TKB-801S Parts Catalog

I’ve lost count how many times I’ve seen a hydraulic breaker torn down to the piston and someone’s holding an aftermarket diagram that shows the wrong seal orientation. That’s a bad day – costly parts and a week of downtime. This Takeuchi TKB-801, TKB-801S Parts Catalog is the real factory binder, 32 pages thick, scanned from the original Takeuchi MFG. release. If you’re working on either the TKB-801 or the TKB-801S and you need the exact part number for that valve assembly or the correct chisel dimensions, this is the document that stops the guessing.

Name and Function of Each Part: What You Get

The first section breaks down every major component on the breaker – the cylinder body, the back head, the valve casing, the front head. You get a labeled structural figure and a separate hydraulic piping diagram. That valve? It’s shown with its specific port locations. If you’re rebuilding or swapping a seal kit, you need to know which port feeds the accumulator. Page 6 in the original document lays out the hydraulic piping flow – don’t skip it.

Do’s and Don’ts: The Safety Pages

Page 3 and 4 have the primary safety matters. Minimum safe distance from power lines – they list transmission voltage right on the page. 6,600V needs 4 meters, 33,000V needs 5. That’s not a suggestion, that’s an OEM spec. The manual also covers proper PPE, handling hydraulic parts under pressure, and what to do before you touch a cap or hose. I’ve read a lot of aftermarket junk that says “depressurize the system” – this catalog tells you how, what tool to use, and the torque on the cap afterward.

How to Adjust Operating Pressure by Adjust Plug

This is where the Parts Catalog becomes a service manual. It walks you through inspection items, the specific bolts involved, gas pressure in the back head gas chamber, and the exact procedure to adjust the operating pressure. If you don’t have a nitrogen gas pressure reading from a known good spec, you’re chasing your tail. The catalog lists the required service tools – including the Gas Charger Ass’y (Nitrogen Gas Charging Tool). That’s a separate part number you can order. Don’t guess the pressure; use the factory data.

Audience Fit: Who Needs This Catalog?

Home garage guys who bought a used TKB-801 at auction – you need this because aftermarket manuals don’t list the bracket types. The catalog has separate sections for Flange Type Bracket and Box-S Type Bracket. Professional mechanics who break down breakers weekly – you’ll appreciate the exploded view for the chisel, seal kit ass’y, and the option parts list. If you’re a fleet manager in San Antonio or anywhere in North America, having the 32-page reference in your shop means your techs aren’t wasting billable hours cross-referencing parts from three different websites.

Source Validity: OEM Factory Print vs. Aftermarket Copies

I’ve seen reprints that blur the part numbers on the hydraulic breaker’s parts list table. This copy – the one you’re buying – is a direct scan of the Takeuchi binder. Every table in the “Hydraulic Breaker’s Parts List & Tools” section is legible. The part number for the valve spool is there, right next to the quantity and description. Aftermarket places like Automotive Industry Overview might have generic hydraulic diagrams, but they don’t have Takeuchi’s specific torque values for the accumulator cap. This does.

FAQ

Does this manual include torque specs for the breaker mounting bolts?

No. This is a parts catalog, not a service manual. It shows part numbers and assembly-level views, not bolt torque values. You’ll need the separate service manual for those specs.

Can I use this to disassemble and reassemble the breaker?

It helps with identification. The exploded views show order of parts, but the catalog doesn’t give you step-by-step disassembly procedures. For that you want the Takeuchi TKB-801/TKB-801S Service Manual. The parts catalog is meant to be used alongside the service manual – you look up the part number, then order the seal kit.

What is the nitrogen gas pressure spec for the TKB-801?

That data is in the service manual’s specifications table, not in this parts catalog. The catalog does list the Gas Charger Ass’y as a service tool option. For the actual pressure value, refer to the operator’s manual or a factory service manual.

How many pages does the catalog have?

32 pages, including the front matter, safety warnings, parts lists, and bracket breakdowns.

If you’re tired of cross-checking part numbers against blurry scans or guessing which valve fits your TKB-801S, stop burning shop time and Access the Factory Manual right now. You’ll have the exact Takeuchi part numbers, the hydraulic piping diagram, and the chisel seal kit options saved on your phone or printed out for the workbench.
