Part of the Yanmar Repair Manuals.
All 264 pages of this Yanmar 2TNV70, 3TNV70, and 3TNV76 Service Manual (OEM #0BTNV-G00202) target one job: returning your 2009–2012 industrial engine to factory condition. Inside you get wiring diagrams, fuel system and lubrication schematics, exploded assembly views, and a full troubleshooting section that runs from quick-reference symptom tables to step-by-step compression pressure tests. Torque tables, periodic maintenance schedules, and complete procedures for the starter motor and alternator cover every system your engine relies on. Head bolts torque to 40–43 ft·lb (53.9–57.9 N·m); plan your fuel filter swap at the 500-hour mark. No more hunting forums for specs your machine was built with from day one. Bookmarked by chapter and keyword-searchable, it opens on your phone right there at the machine.
