Part of the Yanmar Parts Manuals.
All 150 pages of this Yanmar B25 Parts Catalog (OEM #000Y00K2651) are built around one job: finding the exact part number for your 1990-1992 B25 or B25-1 crawler backhoe without guessing. Inside, you get a full picturesque index with exploded views covering every major system, from cab components and engine assemblies to a dedicated hydraulic section with 15 sub-figures. Open to the wiring diagram or hydraulic schematic when you need to trace a component back to its part number before ordering. The specifications page confirms machine identity fast: boom swing 50° left, 90° right; blade width 1,400 × 340 mm; ground pressure 0.27 kgf/cm². Tired of ordering the wrong part because a supplier's cross-reference was two model years off? Every figure is bookmarked and keyword-searchable. Pull it up on your phone or tablet at the parts counter, find the exploded view, read off the number, and order the right piece the first time.
