Part of the Yanmar Repair Manuals.
Bleeding air out of a 3TNV72 fuel system before morning chores is no time to be guessing at the sequence, and the Engine section of this Yanmar EA2400 technical manual runs from the fuel, cooling, and lubrication systems clear through the cylinder head, crankshaft, pistons, and starter motor. It is the deepest chapter in the book, and the one that keeps a diesel tractor from sitting dead in the yard while the weather window closes.
From there the manual widens out: an Electrical section with system specifications, component locations, and circuit-by-circuit diagnosis, plus introduction chapters on the hydro-static transmission, fasteners, fluids and lubricants, and torque tables for the 2005 to 2007 EA2400 (publication 0BTNV-U00300).
At 1001 pages with 547 bookmarks, the PDF drops you on the exact procedure in a couple of clicks, so the tractor is back in the field instead of waiting on the dealer.
