Part of the Yanmar Repair Manuals.
Set a dial gauge on an SVE crankshaft and the question is always the same: are these journals still within limits, or is this the teardown where you order bearings? Section 3, Alignment of Engine, is the heart of this Yanmar service manual and the longest chapter in it, covering measurement limits for cylinder liners, crankshaft and bearings, pistons and rings, connecting rods, and the valve mechanism, plus the full disassembly and reassembly sequences with tightening torques.
Around it sits the rest of the book for the SVE8 and SVE12 marine diesels (including the SVE8G and SVE12G): engine specifications, cooling, lube oil, fuel and wiring diagrams, periodic check tables, fuel injection pump and valve adjustment, starter motor and AC generator service, and a troubleshooting chapter arranged by symptom.
Yanmar publication YT7708-194E runs 123 pages as a PDF, with 42 bookmarks so you land on the section you need in two clicks, and it prints cleanly page by page for the bench.
