Part of the John Deere Repair Manuals.
Three hundred ninety-eight pages stand between you and a skid steer that quits mid-shift, because TM2151 is the John Deere 317, 320, CT322 OPERATION AND TEST MANUAL written to get the 317 and 320 skid steers and the CT322 compact track loader running again without a dealer visit. Harness diagrams trace the engine, cab, and front chassis runs circuit by circuit, down to the back-up alarm and Electric Quik-Tatch wiring. Hydraulic and hydrostatic theory, diagnostics, and tests take up more than a third of the book, with diagnostic trouble code tables you can read straight off the monitor unit. Check boom drift, then measure the boom spool lock solenoid (Y2): 14.8 to 18.2 ohms, and confirm fast idle lands between 2930 and 3070 rpm. Some nights it is you, the machine, and nobody to call. Bookmarked and text searchable, this download is yours once you buy it, for as long as you own the loader.
