Measurements are given in both metric and U.S. units. Use only the correct parts and fasteners, as metric and inch fasteners may need specific wrenches. The John Deere 344G and 444G Loader manuals have two parts: Repair, and Operation and Tests.
Repair sections: Instructions on fixing components.
Operation and tests sections: Help identify routine failures quickly.
Information is grouped by component, including lists of essential tools, equipment, materials, parts kits, specifications, wear tolerances, and torque values. These manuals are concise, job-specific guides for diagnosis, analysis, testing, and repair.
