Yanmar VIO20-1, 3TNE68-NBV, ENBV 2000 Parts Catalog

If you’ve ever ordered a Yanmar part and ended up with the wrong color bracket or a hose that’s 10mm too short, you know the headache. That’s why you need the actual Yanmar VIO20-1, 3TNE68-NBV, ENBV 2000 Parts Catalog. Not a reprint from some third-party that scanned a copy of a copy. This is 148 pages of OEM factory documentation, straight from Yanmar’s last revision (Y00K3472). The catalog includes exploded views, part numbers, paint codes, wiring diagrams – everything a shop needs to order the right piece the first time. Don’t trust aftermarket parts catalogs that mix up revisions; get the real thing.

Painted Color List – Matching Yanmar’s Factory Colors

Yanmar uses specific paint codes for different machine parts. On page 3 of this manual, you’ll find the full painted color list with Munsell numbers and Yanmar color codes: New Deep Green (88), Peacock Green (97), Citrus Green (96), Dark Olive Gray (72), and Natural White. Each color has a corresponding paint part number for 16 kg cans, 4 kg cans, and spray cans. If you’re refinishing a canopy or touch-up, don’t just eyeball it – use the exact paint numbers listed here. Aftermarket paint won’t match the factory finish and will look wrong on a resale or inspection.

Picturesque Index – 64 Exploded Views Across 148 Pages

The catalog is built around a picturesque index system. Figures are grouped: 01-12 cover main parts, 13-24 continue, and so on through Figure 64. There’s a dedicated hydraulic section index (PICTURESQUE INDEX(2)) that helps you track down seals, hoses, and fittings. Each figure shows an exploded view with numbered callouts. Find the figure that matches your machine’s assembly, read the callout number, then cross-reference to the part number table. That’s it – no guessing, no flipping through generic drawings. The manual also includes a separate index for figures 37-48 and 49-60, so you can jump straight to the undercarriage or blade components.

Wiring Diagrams for Parts Tracing

Two wiring diagrams are included: the standard wiring diagram and the one-touch deceleration circuit. These aren’t for diagnostics – this is a parts catalog – but they’re critical when ordering electrical connectors, harness assemblies, or switches. The diagrams show wire colors and component locations. If you need a specific pigtail or relay, trace it on the diagram, note the reference, then look up the part number. Without the factory wiring layout, you’re guessing at connectors that might have been superseded. This manual keeps you on the right part number.

Specifications – Verify Your Engine and Undercarriage Model

Page 2 lists full specifications for the VIO20-1 crawler backhoe: transport length 3740 mm, standard bucket capacity 0.033–0.066 m³, max digging depth 2200 mm, blade width 1480 mm, machine mass 1950 kg (rubber crawler) or 1980 kg (iron crawler). The engine section covers the 3TNE68-NBV and 3TNE68-ENBV – vertical 3-cylinder water-cooled diesel. Travel speeds (high/low) are 4.9/2.4 km/h for rubber, 4.6/2.2 km/h for iron. Track shoe width is 250 mm standard. If you’re ordering undercarriage parts or needing to confirm your engine serial number range (N00545–N02749 for NBV, N06981–N07305 for ENBV), this spec page prevents ordering components from the wrong production run.

Source Authenticity – OEM Yanmar vs Aftermarket Reprints

This parts catalog is the last revised edition, published June 2000 (Y00K3472). The preface includes a history table showing the 1st edition (1997/7), 1st revised (1999/4), and this final edition. Aftermarket sites often repackage older editions without the updates. For example, the wiring diagram difference between the standard and one-touch decel circuits only appears in this revision. I’ve seen shops install a decel solenoid using a part number from a 1997 catalog – wrong part, downtime, customer pissed. Use this OEM print and you’re working from the same data as a Yanmar dealer.

The Yanmar YB301 YB351 1991 Parts Catalog – 248 Pages OEM also covers older models. For background on why OEM documentation matters, see Automotive Industry Overview. Automotive Industry Overview

Frequently Asked Questions

Can I use this parts catalog for engine repairs?

No. This is for parts ordering only, not service procedures.

Does this catalog include part numbers for the hydraulic system?

Yes. The hydraulic section (PICTURESQUE INDEX(2)) has its own index. Figures 01-12 include main hydraulic pump and control valve assemblies, while figures 13-24 cover cylinder and hose routing. Each callout links to a specific part number. The catalog also includes the painted color list for hydraulic components like boom cylinders that have external paint. If you’re rebuilding a hydraulic cylinder, you need this catalog to order the correct seal kit and piston rod – the service manual gives you the disassembly steps, but this catalog gives you the part numbers.

What is the total number of pages?

148 pages total, including the wiring diagrams and paint color list.

How do I find the correct paint code for my machine?

Go to the painted color list section. Compare the color on your canopy or chassis to the Munsell numbers listed. For example, Yanmar New Deep Green uses Munsell 0.6B2.2/4.2 and paint code 88. Order the paint by the part number given (e.g., 981101-09588 for 16 kg can). If your machine’s paint is faded, match it to the closest Munsell value – but always order OEM paint to avoid mismatch.

Don’t waste time flipping through generic diagrams or calling the dealer for a part number you could have looked up in two minutes. The Yanmar VIO20-1 parts catalog is the only source for correct OEM numbers, paint codes, and production-run-specific components. Access the factory manual and keep it on your bench – next time a customer’s machine is down, you’ll have the right part number before you even pick up the phone.
