Part of the Yanmar Parts Manuals.
Within the hour you could be under the B30V-1 with a worn roller in one hand, matching it against the exact assembly Yanmar built for that spot. That is the job this parts catalog does: 15 bookmarked pages for the Yanmar B30V-1 crawler backhoe, including the B30V-1(EP) (B6050) variant with the 3TNE82A-B1A engine, publication 000Y00S3690.
The catalog is organized into six sections: Roller and Adjust, Crawler, Hydraulic Oil Pump and Joint, Turning Motor, and the Control Valve in two parts. Each one lists the assemblies, seal kits, gaskets, shafts, and bearings that belong to that system, so you order the right piece the first time instead of guessing from a photo.
When you are alone in the yard with a dead machine and nobody to ask, a correct part number is the difference between waiting and working. Find it, fit it, and get the backhoe digging again.
