![Fiat 580 580DT Repair Manual [Tractor]](https://youfixthis.com/wp-content/uploads/2013/10/YouFixThis_Traktor_Screen_2_S-300x300.jpg)
This 192-page Fiat 580-580 DT, 680-680 DT Workshop Manual (OEM #603.54.202) covers the 580, 580 DT, 680, and 680 DT tractors built between 1979 and 2000, from the engine block down to the final drive. Inside you get full teardown procedures for the Ferodo and Luk clutch, transmission and mechanical reverser rebuilds, and the complete Hydraulic Lift Unit section with lift pump output charts and remote control valve leakage tests. You also get the electrical system broken down by starter type (Marelli, Lucas, Bosch), plus torque tightening figures for the front axle, live front axle, and lift unit assemblies. Adjust king pin bearing preload and bevel drive backlash to factory spec before you close up the axle housing, not a shop-floor guess. Your transmission is torn down and the reverser's in pieces; get the real sequence instead of reassembling twice. Bookmarked by section so you can jump straight from clutch to lift pump without hunting through pages.

Fiat 580, 580 DT, 680, 680 DT Common Problems This Manual Covers
Fiat 580 DT/680 DT engine loses power and stalls under heavy load while plowing, runs rough at idle
Pull the fuel filter first; it's the most commonly replaced part and a clogged element starves the injection pump under load. Check for water or debris in the fuel system (Engine section, pages 19-42). Hold the engine at rated 540 RPM and verify governor response against the diagnostic test values on page 41, and inspect injector nozzles for worn spray patterns.
Manual Section: Engine p. 41Hydraulic lift fails to raise implements or drifts down under load, loses pressure after 30 minutes
Run the trouble shooting chart on pages 124-129 to isolate whether the fault is pump, valve, or linkage. Pull the lift pump and run the output test on page 142, checking flow against the speed-output chart. Worn pump seals or a failed relief valve typically cause pressure to bleed off after 30 minutes; replace the seal kit and retest.
Manual Section: Hydraulic Lift Unit p. 124Transmission slips or refuses to engage gears, shift lever feels loose and won't lock into position
Check clutch disc wear and pedal free play per the service procedures on page 55; a worn Ferodo or Luk disc causes slipping under load. For a loose shift lever, inspect the splitter shifter rod and synchromesh linkage covered on pages 63 through 65 on the 8-speed or 12/16-speed transmission, and tighten or replace worn linkage bushings.
Manual Section: Power Train: Clutch p. 55Excessive oil consumption with blue smoke from the exhaust under heavy load
Compression test each cylinder and compare to the clearance specifications on page 20; excessive oil use with blue smoke usually points to worn piston rings or hardened valve guide seals. Pull the head and reference the exploded parts view on page 27 to identify ring and guide part numbers.
Manual Section: Engine p. 20Power steering feels heavy, snatches at the wheel, or vibrates through the front wheels at speed
Work through the troubleshooting procedures on page 100 to separate a leaking control unit from worn linkage or a weak steering pump. Bleed the hydraulic system per the power steering section on pages 95 through 109 before condemning any component; trapped air alone causes snatching and front wheel vibration. Cross check flow paths against the hydraulic schematics on page 103.
Manual Section: Front Axle - Steering: Power Steering p. 100Difficult to start after a cold night despite a fully charged battery
Check the starter type fitted, Marelli, Lucas, or Bosch, since each has different brush and solenoid wear points covered in the electrical system section starting on page 155. Test battery terminal and ground connections for corrosion before assuming the starter is at fault; a battery that reads fine at rest can still sag under cranking load.
Manual Section: Electrical System p. 155Frequently Asked Questions
What are the torque specifications for the main bearing caps on a Fiat 680 DT engine?
For the main bearing caps (C₄, pages 25 and 26) on a Fiat 680 DT engine, the recommended torque is 147 Nm (15 kgm, 108 ft lb).
What torque value should be used for the flywheel bolts on a Fiat 580 DT?
The flywheel bolts (C₆, pages 25 and 26) on a Fiat 580 DT should be tightened to a torque of 118 Nm (12 kgm, 87 ft lb).
What are the replacement specifications for the Fuel injection pump?
The manual specifies different injection pump types depending on the tractor model. For the 580, 580 DT, it's a CAV DPA3233 F700-771338, and for the 680, 680 DT, it's a BOSCH EP/VA 4/110H1250 CL-771381 or CAV DPA3342 F470-771414. The firing order is 1-2-3 for 580, 580 DT and 1-3-4-2 for 680, 680 DT.
What are the replacement specifications for the Hydraulic lift control valve?
When replacing parts of the hydraulic lift control valve, spools are supplied matched to their respective valve body, and the relief valve (14) is supplied together with its seat (13). The spool clearance in the body for single and double acting is 0.006 to 0.009 mm (0.0002 to 0.0004 in), and the free spool return spring length is 36 mm (1.417 in).
What is the oil capacity for the engine (with filter and lines) of a Fiat Trattori 580 DT?
The engine oil capacity for a Fiat Trattori 580 DT, including the filter and lines, is 7.6 litres (13¼ pints) or 6.8 kg.
