Part of the Yanmar Repair Manuals.
Torque a cylinder head by feel and you gamble the whole rebuild; Yanmar's figure for the 3TNV88F is 63 to 67 ft-lb on the M10 head bolts, and this service manual is where that number lives. Publication 0BTN4-G00400 covers the Yanmar 3TNV88F industrial diesel across 268 pages, spanning 2012 to 2015 production.
The Engine chapter carries cylinder head, crankshaft and piston, and camshaft and timing gear train specifications for a full teardown. Separate chapters walk the fuel injection pump, engine coolant pump, trochoid oil pump, starter motor, alternator, electronic control harness connections, and electric wiring, and a Failure Diagnosis chapter troubleshoots by measured compression pressure.
It downloads as a PDF you own outright: print the torque tables, keep them at the stand, and put the engine back together to the clearances Yanmar intended.
