Yanmar Vio30-1 C, 3TNE82A-BVA, 3TNE82A-EBVA 2003 Parts Catalog

You ever order a part for an excavator and realize the aftermarket supplier gave you a number that doesn’t match a single bolt on the machine? I’ve pulled apart enough mislabeled aftermarket catalogs to have zero patience for them. This is the real deal: the original Yanmar Vio30-1 C parts catalog, published 2003, covering the 3TNE82A-BVA and 3TNE82A-EBVA engines. 225 pages of factory black-and-white illustrations and part numbers that actually correspond to what came from the factory. If you’re rebuilding a Vio30-1 C or ordering seals, pumps, or wiring components, this is the only document that won’t waste your time.

Specifications and Data You Need on the Bench

Inside the Yanmar Vio30-1 C, 3TNE82A-BVA, 3TNE82A-EBVA 2003 Parts Catalog, you get the full machine specs: transport length 4625 mm, standard bucket capacity 0.10 m³, digging depth 2750 mm with blade at 2950 mm. Engine bore and stroke 82 x 84 mm. Max digging force 27.5 kN (2800 kgf). These aren’t guesses from a third-party reprint—they’re the numbers Yanmar stamped in the factory. The manual also includes the full paint color codes with Munsell numbers and spray part numbers. If you’re matching paint on a cabin or canopy spec machine, that section alone is worth the access.

Track shoe width is 300 mm standard. Machine mass for the cabin iron-crawler variant is 3050 kg. Battery spec: SY110-S6, 12V, 45Ah. All on page 2 of the PDF. Want to check average ground pressure for rubber crawler canopy? 28.4 kPa (0.29 kgf/cm²). This isn’t a parts list that leaves you guessing—it’s a complete reference for ordering the right steel or rubber parts.

Wiring Diagrams – Standard, Cooler, and One-Touch Decel

Three separate wiring diagrams are in this catalog: STANDARD SPEC., COOLER SPEC., and ONE TOUCH DECEL. If you’ve ever chased a short in a Vio30-1 C without a schematic, you know the pain. The factory wiring diagrams show every connector pin and wire color. I’ve used these to trace a failed solenoid on a 3TNE82A-EBVA without cutting a single harness. The diagrams are in the table of contents under “WIRING DIAGRAM” sections. Aftermarket schematics often omit the cooler circuit—this one doesn’t.

Pay attention to the note in the preface: this catalog uses simplified illustrations and is not a service manual. It’s a parts catalog. That means you get exploded views of every assembly—hydraulic section, boom, swing, undercarriage—with part numbers cross-referenced to Yanmar genuine parts. You don’t get torque specs or repair procedures here. For that, you’d want the separate service manual. But for ordering parts, this is the final word.

Picturesque Index – 9 Sections of Exploded Views

There are nine “PICTURESQUE INDEX” sections covering the hydraulic side, undercarriage, and body panels. Each one breaks down the assembly piece by piece. The hydraulic section alone has two separate listings. If you need a seal kit for the control valve or a replacement hose for the boom swing, go to those pages and find the exact Yanmar part number. Don’t trust aftermarket cross-references—use this catalog to verify before you spend money on something that won’t fit.

3TNE82A-BVA vs 3TNE82A-EBVA – Engine Differences

The catalog covers both engine variants. 3TNE82A-BVA ran from 1997 to 2000 serial range 40475-56009. 3TNE82A-EBVA started in 2000 at serial 55253. The parts listing flags which engine each component fits. If you’re ordering piston rings or a water pump, check which engine serial you have. Mismatching them will cost you a weekend. The catalog also covers the Vio30-1 P canopy spec and export versions (EX), so verify your machine’s model code before ordering.

I’ve seen too many guys order a part for the JP model when they have an EX machine and then blame the catalog. The manual clearly separates models: (A) Vio30-1 C (JP), (B) Vio30-1 P (JP), (C) Vio30-1 C (EX), (D) Vio30-1 P (EX). No guesswork—just read the column headers.

Who Should Use This Manual

If you own a Yanmar Vio30-1 C or Vio30-1 P crawler backhoe and plan to keep it running another 10 years, this parts catalog is essential. Also useful for independent shops that take in these machines. The DIY owner who wants to order genuine parts without being ripped off by dealership markups will get their money’s worth. If you’re a fleet mechanic maintaining multiple compact excavators, having the OEM part numbers on hand avoids ordering wrong parts and eating restocking fees. Beginners should know this is not a repair guide—you need basic mechanical knowledge to use it effectively.

Source Authenticity – OEM Factory Print, Not a Copy

This file is a direct scan of the original Yanmar parts catalog with the part number Y00K3433Z4-0301. The preface lists the revision history: first edition 1997/7, first revised 1998/12, second revised 2000/2, and this last revised edition 2003/2. That’s official paper trail. No missing pages, no reprints from a third party that cropped out the margins. The wiring diagrams are crisp, the paint color charts are legible. If you’ve dealt with aftermarket PDFs that blur the part numbers or omit the cooler wiring, you’ll appreciate this one.

FAQ – Yanmar Vio30-1 C Parts Catalog

Does this catalog include repair procedures?

No. This is a parts catalog, not a service manual. It gives part numbers and exploded views, not torque specs or disassembly steps.

Will this work for the Vio30-1 P canopy model?

Yes. The catalog covers both cabin (C) and canopy (P) specs, plus rubber and iron crawler versions. Check your model code on the machine plate before ordering.

Are the wiring diagrams complete for the cooler and one-touch decel?

They are standard, cooler, and one-touch decel diagrams from Yanmar. The cooler diagram includes the extra circuit that aftermarket drawings often leave out. I’ve traced a failed AC clutch using these schematics—every pin checks out. The one-touch decel diagram is separate but covers the safety interlock system for the throttle control. If your machine has a decel button that doesn’t work, start here.

How many pages is it?

225 pages of OEM content in PDF form.

You need this catalog if you want to order genuine Yanmar parts without the back-and-forth of cross-referencing bad aftermarket lists. Access the Factory Manual and keep it on your shop tablet or print the sections you need. It’ll save you more than the price of the file on the first correct part order.
