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.

Tensioning the timing belt.
Act on the tensioner roller (24)so as to align the marks «c»and «d», without detensioning the timing belt
(failing this, restart the operation of adjusting the belt tension).
Hold the tensioner roller (24).
Tighten the nut (23), tighten to 1 ± 0,1 m.daN.
Check the position of the tensioner roller (the alignment of the marks «c»and «d»should be correct).
Remove the tools [1], [2]and [4].
Turn the crankshaft 2 rotationsclockwise.
IMPERATIVE: Never turn it back.
Peg the crankshaft, using tool [2].
Check the position of the tensioner roller (the alignment of the marks «c»and «d»should be correct).
Peg the camshaft pulleys, using tool [1].
If the peg [1]goes in: Loosen the exhaust camshaft pulley screws by 45°.
If the peg [1]does not go in: Slacken the exhaust camshaft pulley screws by 45°.
Bring the exhaust camshaft hub to the pegging position (5), using tool [5].
WARNING: Check that the exhaust camshaft pulleys are not at the end of slots. Otherwise, restart
the operation to position the timing belt.
Tighten the exhaust camshaft pulley screws to 1 ± 0,1 m.daN.
Remove tools[1] and [2].
Complete the refitting.
Initialise the injection ECU (see corresponding operation).
