Part of the John Deere Repair Manuals.
All 526 pages of this John Deere JD570 Technical Manual PDF (OEM #TM-1001) cover the 570 and 570A Motor Graders across their full production run from 1967 to 1987. Inside: complete wiring diagrams for the charging system, starting motor, and electrical circuits, plus hydraulic schematics tracing fluid routing through power steering, brakes, and the main hydraulic system. You get a full troubleshooting section for the Power Shift transmission, page after page of exploded views across all major systems, and torque specifications built into every Power Train procedure. Set your transmission pump to 175 ± 10 psi with the filter relief valve blocked; Differential Control Valve pressure reads 420–480 psi at 2300 rpm on the 570 or 635 ± 25 psi at 2450 rpm on the 570A. Your grader is down. Get factory numbers, not forum guesses. Bookmarked and keyword-searchable; pull it up on your tablet and start wrenching.
