John Deere 8225R 8245R 8270R 8295R 8320R 8345R Tractors Repair Technical Manual TM104319

What's Covered in This Manual

This is the official John Deere TM104319 Repair Technical Manual for the 8225R, 8245R, 8270R, 8295R, 8320R, and 8345R Tractors, covering Serial No. 01001-053099 (and the Russia-spec serial range 001001-052200). This is the repair-focused half of John Deere's two-manual system for this tractor line - this book walks through actual component removal, disassembly, and reassembly procedures, while a separate companion manual, TM104219, handles diagnostics and troubleshooting.

Inside, the manual covers the full range of systems on these large frame R-Series tractors: engine support systems, transmission and powershift or IVT driveline components depending on configuration, front and rear axle service, hydraulics for both the tractor's own systems and remote/implement circuits, electrical system component service, steering, and cab and operator station repair. Specifications, torque values, and wear tolerances are included throughout so a rebuild comes back within factory spec.

This manual is designed to be used alongside several other John Deere publications for complete coverage: the TM104219 Diagnostic Technical Manual for troubleshooting, CTM77 for alternator and starting motor service, and CTM400 covering the PowerTech 9.0 L OEM diesel engines used in this tractor series. Between this repair manual and its companion references, a technician has everything needed to service these tractors from routine maintenance through a full driveline or engine overhaul.
