Part of the Case IH Repair Manuals.
This 603-page International Service Manual (OEM #GSS14703) covers the 786, 886, 986, 1086, 1486, 1586, and Hydro 186 tractors, every system from front axle to closed-center hydraulics. Open it up and you get full wiring diagrams for the cab and instrument cluster, hydraulic schematics covering open-center and closed-center load/position control circuits, and a dedicated troubleshooting section for chasing electrical and hydraulic faults. You also get torque tables, exploded views for the transmission and differential, and step-by-step calibration procedures for the hydraulic system analyzer. Set RPM and MPH transducer lock nuts to 9-11 ft. lbs., and torque the unloading valve body to 47-54 N·m (35-40 ft. lbs.) before you button it back up. No more cross-referencing three parts books to find the right number. This PDF is bookmarked by section, so pull it up on your phone and jump straight to the hydraulic test procedures.
