Part of the Yanmar Parts Manuals.
All 158 pages of this Yanmar Crawler Backhoe B3 Parts Catalog (OEM #000Y00K2363) are built around one job: identifying, cross-referencing, and ordering the right parts for your B3, B3-1, B3-2, B3-P, or B3-PR from the 1988-1996 production run. Inside you get exploded views for every major assembly, from the 3TN84L-RBA engine and hydraulic oil pump to the turning motor, swivel joint, and all five cylinder assemblies. Wiring diagrams cover the full electrical harness and work lamp circuits; hydraulic schematics map the complete oil piping from tank through control valves to each actuator. Your B3-P and B3-PR are rated for a 30-degree climb grade, and every wear item that takes punishment on that terrain, from crawler track components to blade cylinder seals, has its OEM part number listed here. Chasing a part number from a dealer printout that's two machine generations out of date? Bookmarked and searchable, this PDF has the right Yanmar OEM number before you pick up the phone.
