Part of the Yanmar Parts Manuals.
All 148 pages of this Yanmar VIO20-1 Parts Catalog (OEM #Y00K3472) focus on one thing: identifying and ordering the correct parts for your 1997-2000 Crawler Back Hoe without guesswork. Inside, exploded-view assemblies cover every major system: engine, hydraulics, cab, chassis, boom, and drivetrain, each component labeled with its factory OEM part number for direct ordering. You also get a full wiring diagram with wire color codes, relay locations, and fuse box layout, plus hydraulic schematics routing the complete fluid circuit. The Specifications page anchors the catalog with machine data including engine model, rated dimensions, standard bucket capacity, and maximum digging depth, so you can cross-verify fitment before placing an order. Wrong parts cost you a week. Download this catalog, jump to the bookmarked section for your system, confirm the part number, and call your supplier with confidence.
