John Deere 318D and 320D Skid Steer Loader Operation and Test Technical Manual

• This technical service documentation is the John Deere 318D and 320D Skid Steer Loader (EH Controls) Operation and Test Technical Manual TM11406 PDF. It serves as a structured reference for evaluating machine performance, conducting operational checks, and verifying system functionality on these specific skid steer models. The manual is designed to support technicians and service personnel in maintaining reliable machine operation through systematic testing procedures.

• The content focuses on operational verification workflows essential for skid steer loaders equipped with electro-hydraulic (EH) controls. It includes detailed sequences for performing functional tests on the hydraulic system, drivetrain, and attachment control circuits. Each procedure is laid out to help confirm that all machine systems respond correctly under load and during standard operation cycles.

• Diagnostic routines within this manual emphasize fault isolation techniques for the EH control system, which governs joystick commands and hydraulic valve responses. Technicians can follow step-by-step testing methods to identify discrepancies in control behavior, hydraulic pressure levels, or electrical signal integrity. The manual also covers inspection points for sensors, solenoids, and wiring harnesses common to these loader models.

• Operational testing chapters guide the user through machine start-up checks, drive performance evaluations, and lift/tilt cycle timing. These tests are critical for ensuring the skid steer loader meets expected performance benchmarks before returning to service. The documentation also provides reference values for system pressures and component response times, aiding accurate diagnosis during troubleshooting.

• Additional sections address maintenance inspections that support long-term equipment reliability. These include checks for hydraulic fluid contamination, filter condition, and electrical connector integrity. The manual integrates schematic references and test point locations to streamline the diagnostic process, allowing technicians to move efficiently from symptom identification to component testing.
