What This Fiat Workshop Manual Gives You

This is the full factory-issue workshop manual for the Fiat Series 66 tractors, revised to include the new engine assemblies and the mechanical and hydraulic units fitted to the 55-66, 60-66, 65-66, 70-66 and 80-66 models. It carries the complete specification tables, torque figures, wear limits, adjustment values and calibration data that a workshop or a serious owner-mechanic needs to service these tractors properly.

The engine section alone covers the three-cylinder and four-cylinder diesel engines in detail — cylinder sleeves, pistons and rings, crankshaft and bearings, camshaft, valve gear and timing, oil pump and lubrication circuit, cooling system and water pump, and both BOSCH VE and C.A.V. DPS injection pump calibration procedures with full test plans and adjustment values. The power train section takes you through the twin-plate clutch, transmission and splitter, bevel drive and differential, brakes (including the optional transmission brake), and PTO. The front axle, power steering, front wheel drive and hydraulic lift chapters provide the procedures for the live axle, king pin bearing adjustment, hydraulic pump overhaul, lift adjustments and remote control valve servicing.

Electrical coverage includes the alternator and voltage regulator specifications, starter options, battery ratings, fuses, switches, instrument panel and a complete wiring diagram.

Why This Manual Matters

Fiat Series 66 tractors are robust machines, but they are now well into the age where correct service information makes the difference between a quick repair and an expensive mistake. Using the wrong torque figure, an incorrect injection pump timing setting or an approximate valve clearance can lead to poor running, premature wear or costly damage. This manual gives you the exact procedures and the exact figures the manufacturer specified, including the torque tables, wear limits and adjustment values that generic repair guides simply do not contain.

For anyone maintaining a 55-66, 60-66, 65-66, 70-66 or 80-66 tractor — whether two-wheel drive or DT four-wheel drive — this workshop manual is the reference that keeps the job accurate.
