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.

John Deere 2240 Common Problems This Manual Covers
John Deere 2240 hydraulics chatter and lift slowly, three-point hitch raises choppy under a bush hog
Check the hydraulic troubleshooting charts starting for slow operation and foaming before pulling anything apart. Test pump output at 2000 rpm and 138 bar (2000 psi); it should hold 34 L/m (9 gpm) as listed on page 280. Low flow or air ingress means a restricted suction line or worn pump.
Manual Section: Hydraulic System TroubleshootingThree-point hitch drops the implement immediately after shutdown, will not hold position overnight
Pull the rockshaft cylinder and measure the piston, which should hold 82.40 to 82.45 mm (3.244 to 3.246 in.) against a cylinder bore of 82.50 to 82.60 mm on page 316. Replace the piston seal if either is out of range, then torque the cylinder and valve housing cap screws to 50 Nm (35 ft.lbs.).
Manual Section: Hydraulic System p. 316Engine runs erratically or smokes, and the fuel return lines are suspect
Work the fuel system troubleshooting chart on page 90 for erratic operation and smoke; it lists restricted injection pump and nozzle return lines among the causes. Clear the restriction, bleed the system, and torque the bleed plugs to 3.5 Nm (2.5 ft.lbs.) per page 101.
Manual Section: Fuel System Troubleshooting p. 90Will not start even with fuel reaching the injectors after bleeding the system
Verify fuel actually flows from the 62.5 L tank through the transfer pump and filter, not just that the lines feel wet. Follow the no-fuel-at-nozzles chart on page 90, then check the return check valve for blockage. Retorque injection nozzle cap screws to 30 Nm (23 ft.lbs.) if you pulled them for testing.
Manual Section: Fuel System Troubleshooting p. 90Hydraulic pump rattles and the noise changes when steering or lifting the hitch
Isolate the front pump first. Measure pump shaft end play against the 0.1 to 0.9 mm (0.004 to 0.038 in.) range on page 299 and inspect the piston bores, which should measure 17.27 to 17.30 mm. On reassembly torque pump cover cap screws in two stages, 20 Nm then 50 Nm (35 ft.lbs.).
Manual Section: Hydraulic System p. 299Transmission gets hard to shift after about an hour of field work, gears grind when warm
Check clutch linkage free play and oil condition before suspecting internal wear. Drain and refill the transmission-hydraulic system to its 36.0 L dry capacity with clean oil, then recheck shift quality hot. Run the reverser test procedures on page 225 before removing the control valve or clutch packs so you are back in the field before the weather turns.
Manual Section: Reverser Troubleshooting p. 225Frequently Asked Questions
How do I adjust the hydraulic system pressure on the John Deere 2240?
To adjust the hydraulic system pressure, connect a 0 to 250 bar (0 to 3000 psi) pressure gauge to the rockshaft housing. Run the engine at 2000 rpm and record the reading. If the pressure is not within the specified range, remove the plug from the pressure regulating valve in the control valve assembly and add or remove shims to reach the correct pressure. p. 277
What is the torque specification for the cylinder head cap screws on the John Deere 2240?
The torque specification for the cylinder head to cylinder block cap screws is 130 Nm (95 ft.lbs.). Ensure you dip the screws in oil before installation. p. 46
What is the correct valve clearance for the John Deere 2240 engine?
The valve clearance for the engine, whether hot or cold, is 0.35 mm (0.014 in.) for the intake valve and 0.45 mm (0.018 in.) for the exhaust valve. p. 6
What is the engine crankcase oil capacity for the John Deere 2240?
The engine crankcase oil capacity, including the filter, is 7.0 liters (1.8 U.S. gallons). p. 7
How do I bleed the fuel system on the John Deere 2240?
To bleed the fuel system, loosen the fuel filter bleed plug and operate the fuel transfer pump primer lever until a solid stream of fuel without air bubbles is obtained. Then, loosen the lower and upper bleed plugs on the injection pump sequentially, bleeding and retightening each to the specified torque. p. 101
