ENGINE TIMING

– If none of the timing system components have been replaced, timing should be carried out as described in Par.
11.1 "ENGINE DISMANTLING".
– To stretch the belts, fit the tool «1» - Fig. 11-44 cod. 30 94 86 00, as indicated in the figure, after loosening
the 3 belt-stretcher seal nuts by a few turns.
Using a dynamometric wrench, apply a torque of 0.4÷0.48 kgm to the tool and under these conditions tighten in
the following order:
– pin «A» nut
– fulcrum «B» stud bolt;
– screw «C».
The belts must be replaced every 30,000 km without fail, or when, during a inspection, there is any sign of wear
or damage.
NOTE: The belts must always be stretched with the piston in the TDC position, in the combustion
phase (closed valve) or with the upper cam shaft drive pulley without inner gears as shown in Fig. 11-44.
– If any of the timing components have been replaced,
or for an accurate adjustment of the timing, proceed
as below.
DETERMINATION OF THE TDC AND TIMING
The TDC is indicated by the marks on the engine
flywheel (Fig. 11-45).
