Part of the Yanmar Repair Manuals.
Pop pressure on a TNV injector is nothing you guess at, and with the engine on a stand and the nozzles out, this Yanmar service manual (publication 0ETNV-U00102) puts the test values and retainer torques in front of you across 378 pages. It covers the industrial TNV family: 3TNV82A, 3TNV84, 3TNV84T, 3TNV88, 4TNV84, 4TNV84T, 4TNV88, 4TNV94L, 4TNV98, 4TNV98T, 4TNV106 and 4TNV106T, including the -B, -U, -Z and -E variants.
Chasing bearing clearances and head torque sequences through forum posts is a good way to scrap a crank; here they sit in one book. Dedicated chapters cover the base engine, fuel system, cooling, lubrication, turbocharger, starter motor, alternator, electronic control system and wiring, plus a failure diagnosis chapter built around compression testing. The PDF carries 445 bookmarks, so getting from a symptom to the page that fixes it takes seconds, not a flip through the whole book.
