JCB wrote these 1,420 pages (OEM #9813/2700) to cover four excavators at once: the 85 Z-1, 86 C-1, 90 Z-1, and 100 C-1. Hydraulic schematics trace fluid paths through the variable displacement pump, slew motor, and every cylinder ram on the machine; the wiring diagrams follow each harness from main frame out to the boom work lights. The electrical section alone documents 17 fault codes alongside connector pinout charts and calibration steps, and step-by-step procedures cover engine internals, track systems, and the full hydraulic control valve block. Torque the track roller mounting bolts to 259 Nm and pull the slew gearbox capscrews to 86 Nm. No more chasing numbers across three forums. Everything is bookmarked by system and searchable by keyword, so the next answer is one tap away on whatever device rides out to the 86 C-1.
