Part of the John Deere Repair Manuals.
This 267-page John Deere 675 Technical Manual (OEM #TM1374) covers every system on the 675 and 675B Skid Steer Loaders, from engine and power train to electrical and hydraulics. Open it up and you get wiring diagrams for chasing electrical faults, hydraulic schematics for the charge pump and main control valve, and a full torque chart with metric hardware specs so you're not guessing on fasteners. You also get dedicated operation and test sections: system relief valve pressure tests, hydraulic pump flow tests, and boom raise cycle time checks, plus power train and electrical diagnosis procedures. Set your relief valve pressures using the exact factory checkout values in Groups 05 and 10, not a shop-manual approximation. Your loader won't fix itself while you flip through a photocopy. Every section is bookmarked and searchable, so you jump straight from the TOC to the wiring diagram or torque spec you need and get back under the machine.
