Part of the Yanmar Repair Manuals.
Yanmar's EG907PS technical manual (05/2008 edition, 443 pages) strips the EG907 diesel tractor down on paper, system by system: the 4TNV98T diesel, the power reverser transmission with its high/low shift, the independent PTO in the rear axle, power steering, and the cab air conditioner.
When the shuttle drags at dawn and the dealer is an hour away, this is the second set of eyes you do not have. Each section pairs construction and function with disassembly, reassembly, inspection values, and problem diagnosis, and the electrical chapter backs it all up with circuit diagrams for the charge, alarm, security, and cabin systems.
It arrives as a bookmarked PDF, about 100 bookmarks deep, so you can drop straight from the contents into the rear axle PTO pages and be back in the field before the weather turns.
