Part of the John Deere Repair Manuals.
This is the complete John Deere factory technical manual (TM1470) for the 670, 770, 790, 870, 970 and 1070 compact utility tractors. Across 1,020 pages it covers every major system on all six models: engine removal and rebuild split by displacement group, power train and drivetrain repair split between the 670/770/790 and 870/970/1070 families, hydraulic pump and rockshaft service, full electrical system with schematics, steering and brake repair, and a dedicated operational checkout and specifications section. It is the same manual a John Deere dealer technician works from, with the torque values, clearances and test pressures called out so a repair is done to spec the first time.
