Part of the John Deere Repair Manuals.
Three hundred forty-four pages stand between a split reverser housing on your John Deere 2240 tractor and a machine that pulls again by Friday, and this John Deere 2240 technical manual PDF (factory number TM4301) walks you through all of it. The power train section runs the longest stretch in the book, taking the engine clutch, Hi-Lo shift unit, collar-shift transmission, differential and reverser apart in order. Wiring diagrams trace the starting motor and alternator circuits back to the regulator, while the hydraulic chapter maps the pump, valves, oil cooler and rockshaft, with test procedures that end in a pressure reading you can judge. Torque a 10.9 grade 1/2 in. thread fastener to 120 Nm (85 ft.lbs.); snug bleed plugs at 3.5 Nm and no more. Chasing a rockshaft that drops slow is miserable work without real specs. Bookmarked, searchable, downloaded once and yours for as long as you own the tractor.
