CHECKING AND SETTING THE VALVE TIMING
Engine: ES9A
Setting the valve timing (continued).
Refitting.
Check that the camshafts and the crankshaft are correctly pegged.
Check that the rollers and the coolant pump pulley are turning freely (no tightness).
Loosen the camshaft pulley screws by a 1/4 turn.
Make sure that the pulleys are turning freely on the camshaft hub.
Turn the camshaft pulleys in a clockwise direction, to end of slots.
WARNING: Respect the direction of fitting of the belt: Facing the timing, the inscriptions on
the belt should be readable the correct way up.
Fit the timing belt on the crankshaft pinion.
Position the tool [6].
Position the timing belt in the following sequence (belt well tensioned):
- The roller (26), the pulley (18), the pulley (17).
WARNING: Keep the timing belt well tensioned.
- Refit the guide roller (16), tighten to 8 ± 0,8 m.daN.
Position the timing in the following sequence:
- The camshaft pulleys (15)and (14), the tensioner roller (24), the coolant pump pulley and the
guide roller (27).
NOTE: When positioning the belt on the camshaft pulleys, turn these clockwise so as to engage the
next tooth. The angular displacement of the pulleys should not be more than the equivalent of one
tooth.
