Part of the John Deere Repair Manuals.
This is the complete John Deere factory repair manual (TM104319) for the 8225R, 8245R, 8270R, 8295R, 8320R and 8345R row-crop tractors. Across 1,973 pages it walks a technician through every major system on the machine: removing and rebuilding the PowerTech 9.0L diesel with Denso high-pressure common-rail fuel injection, servicing both the 16-speed PowerShift and the infinitely variable AutoPowr/IVT transmission, repairing the rear differential and final drives, overhauling the 1300 and 1500 series MFWD axles and the Independent Link Suspension front axle, and tracing the full wiring harness with connector and routing diagrams. It is the same information a John Deere dealer technician works from, with the torque values, wear limits and hydraulic test pressures called out so a repair is done to spec the first time.
