![Versatile Ford New Holland 256 276 276 II Bidirectional Repair Manual [Tractor]](https://youfixthis.com/wp-content/uploads/2012/02/Manual_Download-300x300.jpg)
This 135-page Ford Shop Manual (models 1120, 1220, 1320, 1520, 1720, 1920, and 2120) puts the complete diesel fuel system, hydraulic lift, and transmission overhaul procedures in your hands for every gear configuration these tractors shipped with. You get full wiring diagrams for the alternator, glow plugs, and starter circuit, plus hydraulic schematics covering the flow control valve, lift control valve, and remote control valve. Troubleshooting charts walk you through hydraulic pressure faults and power steering complaints step by step, and the torque and clearance tables back every spec with real numbers. Check valve clearance during your next teardown and confirm coolant capacity before you button up the cooling system; these aren't estimates, they're the numbers Ford's own techs used. No more flipping through three forum threads to find one torque value. Bookmarked by section and searchable by keyword, so you can pull up the injection pump procedure on your phone before you even wipe your hands.

Ford 1120-2120 Common Problems This Manual Covers
Ford 1120 through 2120 series tractor engine fails to start or cranks weakly despite full battery charge.
Check the injector opening pressure. Remove and test the injectors. Verify the opening pressure reaches 11760 kPa for 1120, 1220, and 1320 models as specified on page 55. If pressure is low, inspect the injection pump and torque the delivery valve holders to 39-44 N·m (page 52).
Manual Section: Diesel Fuel System p. 55Hydraulic lift loses pressure, sags, or fails to hold heavy implements steady during field operation.
Test the hydraulic pump output. For 1120 and 1220 models, verify the rated pump capacity reaches 17.6 liters/minute (4.6 gallons/minute) at 2500 engine rpm (page 121). Inspect the gear to housing end clearance on page 49. Replace the pump assembly if clearance exceeds 0.15 mm (0.006 inch).
Manual Section: Hydraulic Lift System Trouble-Shooting p. 121Excessive engine overheating and radiator coolant loss observed during normal continuous field operation.
Inspect the cooling system components. Test the radiator cap pressure valve to ensure opening pressure is 90 kPa (13 psi) as noted on page 57. Verify the thermostat starts to open at 71° C (160° F). Check the water pump and measure dimension C to 71.95 mm (page 58).
Manual Section: Cooling System p. 57Transmission gear engagement is stiff, or the main synchronized gears slip under heavy loads.
Measure the clutch pedal free travel. Adjust the linkage to achieve 20-30 mm of free travel for 1120 and 1220 models, referring to page 67. Inspect the clutch disc rivet depth on page 69. Replace the disc assembly if the depth measures less than 0.3 mm (0.012 inch).
Manual Section: Clutch p. 67Frequently Asked Questions
What are the torque specs for the main bearing bolts on a Ford 1220 engine?
The main bearing holder retaining bolts for a Ford 1220 engine should be tightened to a torque of 25-29 N-m (18-22 ft.-lbs.). This specification is crucial for proper engine assembly and function. p. 5
What is the torque specification for the flywheel bolts on a Ford 1320?
For a Ford 1320 engine, the flywheel bolts should be tightened to a torque of 59-69 N-m (44-50 ft.-lbs.). This ensures the flywheel is securely attached to the crankshaft. p. 5
