John Deere 790 and 792 Excavator Repair, Operation and Tests Technical Manual (TM1320)

John Deere usually splits repair and diagnostics into two books, but TM1320 keeps both together for the 790 and 792 excavators. You get the tests to find the fault and the procedures to fix it without switching between manuals.

What this manual covers

The manual is organized by component group. Every group starts with what you'll need before you begin: essential tools, service equipment, other materials, parts kits, specifications, wear tolerances and torque values. Then come theory of operation, diagnostics, tests and repair for the diesel engine, electrical system, power train and hydraulic system. The operation and test sections are built to help you find most routine failures quickly before removing anything. It's useful for owners who do their own repairs and for shops that only see one of these machines occasionally. Typical jobs it helps with include tracking down slow or weak hydraulic functions, sorting out electrical faults, and rebuilding power train components once the fault is confirmed.
