Part of the John Deere Repair Manuals.
This is the John Deere TM-1212 Technical Manual for the JD862 elevating scraper, 1214 pages covering the engine, transmission, torque converter, axles, steering, brakes, electrical system and the scraper and haulage device itself. The System Testing section (Section 90) carries a complete foldout Electrical Schematic and Wiring Diagram with numbered wires for harness tracing, plus a foldout Hydraulic Schematic covering the main hydraulic, elevator, bowl, ejector, steering and brake circuits. Component specifications, clearances and torque values are printed throughout, from engine crankshaft and camshaft fits to the bowl, ejector and sliding-floor cylinder specs and cutting-edge bolt torques.
