Part of the Yanmar Parts Manuals.
All 204 pages of this Yanmar B50-P(R), B50-O(R), and B50-C(R) Crawler Backhoe Parts Catalog (OEM #Y00K2511-1) are built around one job: putting the correct OEM part number in your hand before you spend an hour on hold with a dealer. Inside, exploded views walk through every major system, from cab assembly and engine mounts to control valves, travel motor internals, and boom cylinder components, with a wiring diagram covering the full electrical system. Part numbers run through every section: track roller O-rings, pilot valve shims, hydraulic piping connectors, bucket teeth assemblies, and everything between. The model chart confirms your B50-O(R) reaches 5100 mm cutting depth and 3550 mm dumping height, so you're ordering parts matched to the right variant. Wrong part number, two-week wait. Bookmarked and keyword-searchable; pull up the section you need and have the OEM number ready before you call the counter.
