Since its first introduction in 1971 the FIAT 127 has undergone a continuing programme of improvements concerned mainly with styling and trim alterations. However, in 1977 a new model range was introduced which included the option of a larger engine of 1049 cc capacity with a single overhead camshaft. This engine is of overhead camshaft design, using shims for valve clearance adjustment. The crankshaft is supported in five main bearings, the center one incorporating the thrust washers which control crankshaft end float.
An auxiliary shaft, driven by the toothed camshaft belt, is used to drive the distributor and the fuel pump. 3 Most major engine components can be removed while the engine is in the car, but operations on the crankshaft, main bearings and flywheel can only be carried out after the engine has been removed.
