Part of the Yanmar Parts Manuals.
All 126 pages of this Yanmar YB101, B10 Excavator Parts Catalog (OEM #000Y00K2131) exist for one purpose: getting you the exact part number for every component on your crawler backhoe, whether you're running the YB101-2, YB101UZ(-2), or B10-R. Inside, exploded-view diagrams break every assembly into individually numbered components, from hydraulic oil pump and valve internals down to individual O-rings, seal sets, and spool bolts. You get complete parts listings for all five hydraulic cylinders, the full drivetrain (final case, sprocket, idler, track roller), cab and canopy components, and the entire hydraulic piping network from tank to swivel joint. The preface cross-references machine number ranges across all variants, so you confirm the right part number before placing an order. Your machine is down and the dealer wants a week. Bookmarked by system, searchable by keyword; pull the part number, make the call, get back to work.
