Part of the John Deere Repair Manuals.
Technical Manual TM-1093 strips the John Deere 690B, JD690-B excavator down to its individual castings and builds it back up, and the John Deere 690b, jd690-b technical manual pdf runs 628 pages doing it. Wiring diagrams trace the charging and starting circuits back through the gauge cluster and the switches behind it. System testing takes up the longest stretch of the book, pairing hydraulic schematics with analyzer procedures that walk the rotary manifold leakage test and the relief valve checks to a pass or fail number, not a shrug. Set the boom relief at 3000 psi (20 685 kPa), verify the 5 in. (127 mm) boom cylinder bore before you order a seal kit, and check crowd and bucket rod diameter at 3.25 in. (83 mm). Bookmarks and searchable text put you in the right section in seconds.
