Part of the Yanmar Repair Manuals.
Torque a 6CXM-GTE cylinder head from a forum guess and you find out at sea whether the gasket held. Yanmar publication M9961-H13021 is where the real numbers live: the factory service manual for the 6CXM-GTE and 6CXM-GTE2 marine diesel engines, 132 pages of the procedures Yanmar's own technicians work from, delivered as a PDF.
The book walks the whole engine: disassembly and reassembly, then inspection and servicing of the cylinder head, pistons and piston pins, connecting rods, cylinder sleeves and block, crankshaft and main bearings, camshaft and valve gear, timing gear, lube oil, cooling water and fuel oil systems, electrical equipment, and the turbocharger. Wiring and piping diagrams and specifications sit in the General section up front.
Service standards, adjustment and check values, a tightening torque table for the major bolts, and a symptom-based troubleshooting chapter close it out. Bought once, it stays with the engine.
