Document number 93213-00593 marks this as Kawasaki's own factory book for the 90Z7 and 92Z7 wheel loaders, reproduced in full as an 898-page Kawasaki 90Z7, 92Z7 shop manual PDF. Hydraulic schematics trace oil from the pump device through the control and steering valves to the bucket and lift arm cylinders; wiring diagrams map the ECM, controller and electrical system. Troubleshooting fills more than a third of the book, with monitor fault codes, diagnosing procedures and performance tests that tell you whether the engine, drive unit, axles and brake valve still meet standard. Set declutch control pressure to 1.5 MPa (218 psi) in first gear with the brake pedal fully applied, and torque 8 mm pipe nuts to 11.8 to 14.7 N·m (8.7 to 10.8 lbf·ft). An intermittent harness fault can eat a whole shift. Your bookmarked copy rides along on a laptop or tablet, in the cab or out at the pit, wherever the loader is parked.
