Takeuchi TKB-70 2001 Parts Catalog – OEM Factory Parts List

I’ve been turning wrenches for 28 years, and the one thing that burns my ass faster than a seized through bolt is a parts catalog from some third‑party outfit that transposed part numbers in Excel. You order a diaphragm plug, you get a gasket. You get a front head bushing, you get a chisel pin. Then you’re down a week waiting for the real part. This Takeuchi TKB-70 2001 Parts Catalog is what the dealer would hand you if you walked in the back door — 16 pages, OEM part numbers, section drawings, and the actual spec sheet Takeuchi printed for the TKB-70 hydraulic breaker. No reprints. No scanned copies with blurry numbers. Original factory file.

Parts Breakdown: What You Get on Page 1

Page 1 of the catalog is a straight‑up parts list with section drawing references. Every component from the Back Head (item 1) to the Chisel (item 56) has a Takeuchi part number and the quantity you’ll need. The drawing column uses letters and callouts so you can match the exploded view on pages 2–3 without guessing. Need an Accumulator Assy? It’s item 6, part TS17-10-6000. Front Head Bushing (Front) is item 34, part TS17-70-121A. The catalog also cross‑references machines that use the same breaker — TKB10S and TB15 are listed on the top of the page, so you can confirm fitment without digging through dealer portals. I’ve used this catalog myself to rebuild a TKB-70; it saves you the trip of returning a wrong Through Bolt Gr (item 26).

Specifications from the Factory – Page 3

Flip to page 3 and you get the raw spec sheet. Overall weight without chisel: 91 kg (200 lb). Overall length breaker only: 662 mm (26 in). Working pressure: 90–110 kg/cm² (1,280–1,565 psi). Oil flow: 15–32 ℓ/min (4–8.5 gal/min). Number of blows: 450–1,100 bpm. This isn’t a generic “approximate” table — these are Takeuchi’s test‑bench numbers. If your breaker’s blow rate is off, you check oil flow and pressure against these specs before you start swapping pistons. The chisel diameter is 45 mm (1.77 in), and the catalog lists four chisel options: Moil point (TS17-99-0010), Straight (TS17-99-0020), Flat X (TS17-99-0030), and Flat Y (TS17-99-0040). If you’re buying aftermarket chisels, you can cross the diameter and length against the factory dimensions printed here.

OEM Part Numbers: Why Guessing Costs You Money

A hydraulic breaker works at pressures that’ll blow a seal in seconds if the O‑ring groove is off by 0.5 mm. The catalog lists every seal and O‑ring with its factory number — O‑ring item 3 (part VV67-12-111A), Socket Bolt item 14 (TS20-02-022), Valve Retainer Assy item 22 (TS17-20-0560). I’ve seen shops buy a generic “kit” and end up with a Diaphragm (item 7) that’s the wrong thickness, causing the accumulator to lose nitrogen. That’s a day of labor flushed down the drain. This catalog gives you the exact part number Takeuchi put on the bin, so you order once. It’s not a service manual — you need the Takeuchi TKB-70 Technical Manual for torque specs and assembly steps — but without the right parts you’re not fixing anything.

3 Reasons to Use a 2001 Factory Parts Catalog

First, Takeuchi stopped making some of these components for the TKB-70 after 2003. The catalog tells you the original part number, which is what a dealer’s supersession database will cross to a new number if it exists. Second, the section drawings on pages 2–3 show you how the Accumulator Gr (item 5), Cylinder Assy (item 16), and Piston Gr (item 24) nest together. You can see which O‑rings seal which joint without disassembling the whole breaker. Third, the part numbers here match the Takeuchi parts system globally. If you’re tracking down a Coupling S2 Half (item 49, part TV06-15-1410), you can hand that number to any Takeuchi dealer and get the right fitting.

I’ve got the Takeuchi TKB-70 Service Manual sitting in my bay for the rebuild procedure, but the Parts Catalog is what I pull up on the tablet when I’m writing the order. Two different tools, one job.

Order the Right Chisel and Seals Using This Catalog

Chisels are item 56 with four variations. The catalog lists part numbers for Moil, Straight, Flat X, and Flat Y tips. If your breaker came with a worn chisel and you can’t read the stamp, measure the shank diameter (45 mm) and overall length (940 mm with chisel, per spec sheet). Then check the section drawing code — the catalog shows a callout to Chisel Set Pin (item 39, part TS17-80-132A) and Spring Pin (item 41) that hold the chisel in. Replacing a chisel without the correct set pin means the pin can shear. That’s a safety hazard. The catalog doesn’t include torque values (that’s in the Takeuchi TL26 Parts Catalog – 288 Page OEM Factory Manual for the carrier, not the breaker), but it does give you every fastener part: Cap Nut (Rear) item 28, Through Bolt Washer item 30, Grease Nipple item 37. No guesswork.

If you’ve ever rebuilt a breaker from a generic parts drawing, you know the feeling of having four O‑rings left over and a leak. This catalog eliminates that. I’ve been in this trade long enough to trust OEM documentation over anything a third‑party publisher scrapes off the web. The Automotive Industry Overview page won’t help you with a TKB-70 — this will.

Does this parts catalog include torque specs for the TKB-70?

No. Use the Technical Manual for torque values.

Are the part numbers still current if Takeuchi superseded them?

The catalog prints original 2001 numbers. Dealers use these to look up supersessions. For example, the Accumulator Hose (item 44, part VV61-12-0000) was replaced in 2005 with TS61-12-0050. Your dealer will need the original number to find the update. Without this catalog, you’d be ordering by guess. I’ve had to spend 45 minutes on the phone with a dealer because a customer brought in a breaker with no part numbers visible. With the catalog, I look up the section drawing, find the callout, and hand them a number. Five minutes, done. Also, check the Automotive Industry Overview for general equipment sourcing, but for Takeuchi parts, stick to this catalog.

If you’re rebuilding a TKB-70 hydraulic breaker and you want the parts the factory spec’d, you need this 16-page catalog on your bench. Access the Factory Manual now and keep the right part numbers in front of you.
