Fiat's publication 603.64.171.00R packs the operating and servicing instructions for four 56-series tractors into 90 pages, and this Fiat 70-56 operator manual PDF is that same factory book, complete. A cab-version electrical sheet traces those circuits down to the wiper motor, fan-heater unit and work lights, and the lubrication and adjustment chart pins the settings you reach for most: master clutch free travel, brake pedal travel, fan belt deflection, valve clearances. A lift-operation guide matches settings to mouldboard plows, disc plows, harrows and subsoilers, and separate chapters handle the four-wheel drive, 12-speed and No-Spin versions. Set master clutch pedal free travel at 40 mm and torque the wheel nuts to 314 N·m before serious drawbar work. Guess at either and you buy the repair twice. Pay for this bookmarked, keyword-searchable PDF once and it belongs to you for every season this tractor works your ground.

Fiat 55-56, 60-56, 65-56, 70-56 Common Problems This Manual Covers
Fiat 55-56 hydraulic lift slow to raise plow, drops under load when lever held up
Check hydraulic oil level on the dipstick with the tractor parked on level ground and all cylinders retracted. Verify the position control lever travels its full range, then review correct lever settings for plows and harrows in the lift operation guide starting on page 33. Let the oil warm 5 minutes before judging lift speed below 10 C (50 F).
Manual Section: Guide to Lift Operation p. 33Engine cranks slowly or will not turn over on cold mornings, dash lights dim
Check battery terminals for corrosion and clean them to bright metal, then coat with grease. Verify the 12-volt battery is fully charged before cold weather sets in. Follow the flat battery starting procedure in the electrical section on page 54 if the engine still drags, and let the starter rest 30 seconds between attempts.
Manual Section: Electrical System p. 54Engine dies in the field and will not restart after running the fuel tank empty
Fill the tank and bleed air from the fuel lines, following the procedure for your CAV or Bosch injection pump. Loosen each bleed screw in order, work the hand primer until fuel runs free of bubbles, then retighten. When restarting, crank in bursts of 15 seconds or less, and keep the tank above one-quarter full on hillsides.
Manual Section: Fuel System BleedingPTO shaft will not engage or slips and stalls the baler under heavy load
Verify the PTO lever seats fully in its detent with the clutch pedal pushed to the floor, then set engine speed so the tachometer reads 540 rpm at the PTO mark. Check the engagement procedure in the operation section starting on page 21. If the shaft still slips under load, have your dealer check the PTO clutch before harvest.
Manual Section: Operation p. 21Loud clicking from rear axle on tight turns with No-Spin differential fitted
Drive the tractor in a tight circle at walking speed, about 3 km/h (2 mph), on firm ground; steady, rhythmic clicking from the inside rear wheel is normal No-Spin operation. Check the operating notes and test procedure in the No-Spin section starting on page 73. If clicking continues while driving straight ahead, have the unit inspected before fall tillage.
Manual Section: No-Spin Version p. 73Frequently Asked Questions
What is the torque specification for the front axle clamp bolts on the 55-56, 60-56, and 65-56 models?
The clamp bolts for the front axle beam extensions must be torqued to 220 N-m, which is equivalent to 22.5 kgm or 163 ft lb. p. 42
What are the valve clearance specifications for the Fiat 55-56, 60-56, 65-56 and 70-56 engine?
The normal valve clearance for the engine is 0.25 mm (0.010 in) for the intake valves and 0.35 mm (0.014 in) for the exhaust valves, measured when the engine is hot or cold. p. 61
What is the total cooling system capacity for the 65-56 and 70-56 models including the cab heater circuit?
The total cooling system capacity for the 65-56 and 70-56 models, including the cab heater circuit, is 16 liters or 3 1/2 gallons. p. 80
What is the correct fan belt deflection on the Fiat 55-56, 60-56, 65-56 and 70-56 tractor?
The fan belt should have a deflection of 10 to 11 mm (approximately 1/2 inch) when applying a load of 78 to 98 N (8 to 10 kg or 18 to 22 lb). p. 49
What is the fuel injector release pressure for the Fiat 55-56, 60-56, 65-56 and 70-56?
The fuel injectors should be set to a release pressure of 230 to 238 bar (235 to 243 kg/cm² or 3,335 to 3,524 psi). p. 49
