Part of the Yanmar Parts Manuals.
Chase one wrong digit in a bearing number and you will pull a fresh rebuild back apart to fix it. That is what Yanmar's own parts catalog for the 3TNE68-EBVB, publication Y00B6920, is there to prevent: every component on its exploded diagrams carries the factory part number, so what you order is what the engine left the plant with.
The catalog runs 33 pages across 16 bookmarked sections, from Cylinder Block and Crankshaft & Piston through the Lub. Oil System, Cooling Water System, Fuel Injection Device, Governor, Starting Motor, and Generator, closing with the Gasket Set & Tools listing. It applies to the engine itself, whatever it happens to power.
As a 0.59 MB PDF download, it opens on the phone beside the stand or prints page by page, so the injection pump listing can sit next to the pump while you order plungers, delivery valves, and shims.
