DISASSEMBLY/REASSEMBLY
Then tighten again the belt tightener fastening nut to a 40÷44 Nm torque (fig. 57).
Tighten the fastening nut of the camshaft toothed pulley to 70 Nm (fig. 58).
Close the safety lock onto the camshaft fastening nut (fig. 59).
Now remove both timing pins to allow the camshaft and the crankshaft to rotate (fig. 60-61).
Plug the hole on the camshaft support by using a copper seal and the special plug (fig. 62).
Use the flywheel to make the crankshaft rotate two or three times in order to settle the timing belt.
By using a special tool, check that the toothed timing belt tensioning is correct (fig. 63). In our example, the tool used is supplied
by DENSO.
To read the correct tensioning value, place the tool sensor onto the belt tooth (fig. 64).
The correct tensioning value should be within 25 and 28 Kg (fig. 65). Should this not be case, loosen the belt tightener and
increase or decrease tension according to the value read.
Retighten the belt tightener fastening nut to the set torque, make the driving shaft rotate two or three times, then check
again the belt tension by using the tool.
