Part of the John Deere Repair Manuals.
Hunting for a John Deere 301 technical manual PDF straight from the factory? This 344-page Technical Manual (OEM TM-1034, John Deere Dubuque Works) covers the JD301 and JD401 tractors together with the 7310 and JD401-A loaders and the 9250 backhoe, from tune-up and lubrication all the way through full tractor separation. Both engines are documented side by side, so the tables print a value for each: connecting rod cap screws take 65 ft-lbs on the diesel against 45 ft-lbs on the gasoline engine, and exhaust valve clearance is 0.018 in. against 0.022 in. Inside you get the full-machine electrical schematic with its wire-colour routing table and component connector pinouts (pages 94-96), covering the charging, starting, ignition and lighting circuits, plus colour-coded hydraulic system diagrams for both the Hi-Lo Shift and Reverser tractors (pages 226-227) and the rockshaft circuit (page 260). You also get diagnosis charts for the engine, fuel system and power train, with page after page of clutch, transmission, reverser and Hi-Lo shift procedures. Verify your charging output against the 12-volt specs before you condemn a good alternator. Bookmarked by system, this scanned PDF opens on any device; carry your tablet to the machine and start wrenching.
