Part of the John Deere Repair Manuals.
TM2365 is the factory technical manual for the John Deere 3320, 3520 and 3720 cab tractors, all 2101 pages of it. This is the book the dealer techs used: engine repair and testing for all three diesels, the eHydro hydrostatic transmission with pump, motor, charge and loop pressure tests, final drives and axles, hydraulics with Group 15 schematics, steering, brakes and cab HVAC. Electrical gets two full sections, one for North American machines and one for EEC European spec, each with its own component location drawings, harness legends and Main Wiring Schematic sheets you trace with a meter. Every spec is here, from the 2600 rpm rated speed to the 5580 psi hydrostatic loop pressure.
