John Deere 318E and 320E Skid Steer Loaders Operation and Test Technical Manual (TM13006X19)

You’ve got a 318E throwing a hydraulic warning, boom’s dead in the air, operator staring at you. You can poke around for two hours, or you can open TM13006X19 and go straight to the right test port, the right connector, and the right spec. That’s how this thing prevents downtime: it tells you exactly what “normal” looks like on this machine, so you stop guessing and start proving.

Key Tasks Covered:

• Trace hydraulic warning codes to specific pressure, flow, or temp tests.
• Pin‑out and voltage test every major controller and sensor on 318E/320E.
• Run step‑by‑step HST and drive motor performance checks under load.
• Verify pilot control pressures and boom/bucket circuit relief settings.
• Diagnose CAN bus issues between display, ECU, and hydraulic controller.

Common Questions:

Q: “Pump sounds fine, but I’ve got weak hydraulics and no codes. Now what?”

A: Manual walks you to charge pressure and main pump standby pressure tests; if either’s low, you adjust relief or condemn the pump with numbers, not guesses.

Q: “Machine won’t move, park brake light’s off, what am I missing?”

A: It has you check drive enable circuit voltage, seat switch input, then servo pressure—usually finds a dead interlock or no pilot pressure.

Safety Note

Always mechanically support the boom before cracking any hydraulic line, no exceptions.
