Yanmar B17-2 1994 Parts Catalog – Factory Specs for Crawler Backhoe

If you’re wrenching on a 1994 Yanmar B17-2 crawler backhoe and you don’t have the factory parts catalog, you’re ordering blind. I’ve seen guys spend a whole day cross-referencing aftermarket sites only to get the wrong hydraulic seal. The Yanmar B17-2 1994 Parts Catalog stops that. It’s 116 pages, direct from Yanmar’s printing in January 1994, and it covers every bolt, hose, and grommet on this machine.

Page 2 gives you the full spec sheet: engine model 3TNE68L-UBD, 3-cylinder water-cooled diesel. Transport length 3680 mm (144.9 in), width 1000 mm (39.4 in), height 2210 mm (87.0 in). Machine mass 1460 kg (3219 lb) with rubber tracks, max digging depth 2280 mm (89.8 in). All those numbers come straight from the factory—none of this “estimated” aftermarket nonsense. You need the boom swing angle? It’s there: 1540 mm (60.6 in) min swing radius. Bucket capacity 0.045 m³ (0.059 cu yd). For the broader context of construction equipment, check the Automotive Industry Overview on Wikipedia.

Specifications for the B17-2 Crawler Backhoe

This section on page 2 isn’t filler. It lists transport dimensions in metric and I’ve added Imperial equivalents because that’s how we work here. Travel speed (high/low), gradability, average ground pressure with standard shoe width 230 mm (9.1 in)—it’s all there. The table also shows differences between steel and rubber crawler variants (B17-2-CR vs B17-2-PR). Machine mass for the rubber version is 1580 kg (3483 lb). You’ll also find the blade capacity (0.06 m²) and standard bucket width (450 mm outside).

Paint Color Codes: Matching Original Yanmar Finishes

Pages 3 and 4 document the exact paint codes for every exterior component. Yanmar New Permanent Yellow (S.2Y8.5/11), Deep Green (6.3BG2.1I/1.76), New Deep Green (0.6B2.2/4.2), Grayish Green, Dark Olive Grey, and Charcoal Gray. Each has a Munsell number, color division code, and paint numbers for 16N can and spray. The table also lists part codes for each color. If you’re repainting a canopy or frame, you order the exact spray can: 977620-30871 for New Permanent Yellow. No mixing guesswork.

Parts Name Diagrams: Identifying Components Quickly

Page 5 starts the illustrated parts breakdown. Each figure has a name matching the Japanese and English labels: CANOPY (Fig.24), LABEL (Fig.2), RADIATOR & MOUNT (Fig.7), FUEL PIPE LINE, ENGINE FEED, CYLINDER HEAD, HYD. OIL CLUTCH ASS’Y INT (Fig.25), and more. The diagrams show every sub-assembly with callouts. You don’t need to decipher a messy scan—this is a clean factory PDF. The wiring diagram is also listed as a separate section near the end.

Wiring Diagram Section: Tracing Electrical Faults

One of the reasons you buy a factory parts catalog is the wiring diagram. The B17-2 catalog includes it—though the exact page number isn’t listed in the TOC bookmarks, it’s there. You get the complete harness routing, connector locations, and ground points. Without this, diagnosing a no-start or intermittent light on the backhoe means pulling panels and guessing. With the factory wiring diagram, you trace the circuit from battery (Fig.8) through electric panel (Fig.9) to work lamp (Fig.10) and heater (Fig.11).

3 Reasons to Trust the Factory Parts Catalog

First, these part numbers are the same numbers Yanmar stamped on the production line. Second, the catalog lists local procurement codes—172180- OOOOO for parts sourced locally—so you know which items you can get from non-Yanmar suppliers. Third, the engine section includes the exact 3TNE68L-UBD variant and its attached components. Aftermarket parts catalogs often combine multiple model years or use superseded numbers. This one is model-year-specific: 1994, B17-2 only. That’s reliability you can’t get from a third-party site. See also Yanmar YB271, B27 1994 Parts Catalog – OEM Factory Specs for a similar machine.

Who Should Buy This 1994 Parts Catalog?

If you own a B17-2 and do your own maintenance, you need this. If you run a small repair shop that sees these backhoes, you need this. It’s also useful for equipment dealers who need to verify part numbers before ordering. The catalog is in English and Japanese, with parts names and figure numbers clearly legible. Beginners can use the diagrams to learn where components live; seasoned techs use it to cross-check before cutting a torque wrench loose. Pair it with Yanmar YB301 YB351 1991 Parts Catalog – 248 Pages OEM if you work on larger Yanmar backhoes too. For general automotive industry context, you can also refer to the Automotive Industry Overview.

What model years does this catalog cover?

Only the 1994 model year for the B17-2 series.

Does it include engine internal parts for the 3TNE68L-UBD?

Yes, the catalog covers the entire machine, including the engine section (ENGINE FEED, CYLINDER HEAD, FUEL PIPE LINE). Part numbers for pistons, rings, gaskets, and the injection system are listed under the appropriate figures. However, it’s a parts catalog, not a service manual—it won’t tell you how to rebuild the engine, but it will tell you exactly which part to order. Use the figure numbers and page references to locate the correct assembly.

Is the wiring diagram in color?

It’s a black-and-white line diagram, but the connector labels and wire colors are clearly indicated.

Can I use this catalog for a B17-2C or B17-2P model?

Yes. The table on page 1 lists four variants: B17-2 CR AY, PR AY, C AY, and P AY, each with its own machine code (172180A through 172180D). The catalog covers all of them; just match your model code.
