Yanmar B27-2B, 3TNE82A-B1 1998 Parts Catalog

If you’re ordering parts for a Yanmar B27-2B, 3TNE82A-B1 1998 Parts Catalog and you grab a generic aftermarket catalog, you’re asking for trouble. I’ve torqued enough head bolts to know that using the wrong gasket or seal means a teardown. This 236-page OEM parts catalog from Yanmar gives you the factory part numbers and exploded views so you order the right piece the first time. No wasted weekends waiting for the wrong seal.

What This Parts Catalog Actually Covers

Open the preface on page 1 and you’ll see exactly which models this applies to: B27-2B crawler backhoes with canopy or cabin specs, front or side configurations, and the 3TNE82A-B1 engine (serial number 15601 and up). The table of contents runs through SPECIFICATIONS, VEHICLE PAINTED COLOR, PAINT PART No., and then the PICTURESQUE INDEX sections — three separate indexes: MAIN PARTS, HYDRAULIC SECTION, and then FIGURE 01-12 through FIGURE 97-105. That’s 236 pages of detailed part callouts with Yanmar genuine part numbers.

Specifications on Page 2 – Engine and Dimensions

Page 2 lays out the machine specs in a table you can use to verify you’ve got the right variant. Engine bore and stroke: 82 × 84 mm. Transport length 4480 mm, width 1550 mm, height varies by canopy or cabin. Standard bucket capacity 0.080 m³ (0.105 yd³), max digging depth 2650 mm (8.7 ft). Machine mass: 2750 kg (6063 lb) for iron crawler canopy. These numbers matter when you’re ordering undercarriage parts or hydraulic cylinders. The catalog also notes travel speeds, gradability, and ground pressure — all useful for confirming your machine’s configuration before ordering.

3 Picturesque Index Sections for Fast Part Location

Instead of flipping through a parts list blindly, Yanmar organized this catalog with three picturesque indexes. The first covers main parts — engine, drivetrain, chassis. The second zeroes in on the hydraulic section — pumps, valves, cylinders, hoses. The third index breaks down figures 01 through 105, each showing an exploded view of a specific assembly with callouts. If you need a seal for the swing cylinder, you jump to the hydraulic section index, find the figure number, and get the part number. No scrolling through generic diagrams that skip details.

Why OEM Beats Aftermarket Parts Catalogs

Aftermarket catalogs repackage part numbers from unknown sources. They might cross-reference a “universal” seal that doesn’t fit the Yanmar B27-2B’s hydraulic system. The preface on page 1 warns you directly: “Be careful not to use the simple parts available in the market; otherwise their use in repairing causes such an early breakage.” That’s straight from Yanmar. This catalog only lists Yanmar genuine parts — paint colors with Munsell numbers, 88 for Yanmar New Deep Green, 97 for Peacock Green. You can’t get that from a third-party list.

Who Should Buy This Catalog?

Anyone who owns or services a Yanmar B27-2B backhoe with the 3TNE82A-B1 engine needs this on their bench. Shop owners — keep a copy so your techs don’t order wrong parts. DIY mechanics — stop cross-referencing parts from a memory. Home garage enthusiasts — if you inherited one of these machines, this catalog saves you from chasing discontinued parts. Even professional mechanics will use the paint codes and hydraulic section diagrams to restore vintage Yanmar equipment.

Does this parts catalog include torque specifications for the 3TNE82A-B1 engine?

No. It’s a parts catalog, not a service manual.

Can I use this catalog to order parts for a different Yanmar model?

This catalog is specific to the B27-2B chassis and 3TNE82A-B1 engine. While some part numbers might cross to other Yanmar machines — like filters or seals — using it for a different model risks ordering incorrect components. Yanmar made separate parts catalogs for each series. Sticking to the right document keeps your inventory accurate and your machine running. If you need a related manual, check the following options.
