Part of the John Deere Repair Manuals.
TM1221 is the 586-page John Deere 2040, 2240 Technical Manual PDF (Serial No. 350,000-up) that Deere wrote for its own service departments, covering the Roto Diesel fuel injection pump, the rockshaft, and every other system end to end. Factory wiring diagrams trace every harness from the alternator through the lighting circuits, and the hydraulic section walks through system tests on the pump, rockshaft, and selective control valves before you ever split a housing. Power train coverage runs from the Hi-Lo shift unit and reverser transmission through the differential, final drives, and independent PTO. Set up the 2-post ROLL-GARD with crossbar cap screws and U-bolt nuts torqued to 230 N·m (170 ft-lbs), torque front wheel rim-to-hub bolts to 180 N·m (130 ft-lbs) on tractors without MFWD, and hold clutch pedal free travel at roughly 25 mm. Guess on a clutch adjustment and the price is a second split. Bookmarked and text-searchable, this download puts the right torque and clearance figures in front of you instead of a forum guess.
