CHECKING AND SETTING THE VALVE TIMING
Engine: ES9A
Setting the valve timing.
Remove the components as necessary for the operation.
Remove the screws (19)and the plate (20).
Peg the crankshaft, using tool [2].
NOTE:Damp the rotation of the camshafts (15)and (17), using tool [6].
Untighten the camshaft pulley screws (15)and (17).
NOTE: Damp the rotation of the camshafts (14)and (18), using tool [5].
Untighten the camshaft pulley screws (14)and (18).
NOTE:Lubricate the tools [1], with grease G6 (TOTAL MULTIS).
Peg the camshafts, using tools [1], [5]and[6].
Remove the screw (21)of the panel (25).
Untighten the nut (23)of the tensioner roller (24).
Untighten the screws (22)of the panel (25).

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.

CHECKING AND SETTING THE VALVE TIMING
Engine: ES9A
Setting the valve timing (continued).
Adjusting the timing belt tension.
Preliminary operations.
Pivot the plate (25)of the tensioner roller (24), using a spanner (type FACOM S.161).
Engage the screw (21)on the plate (25).
Tighten the screws (21)and (22), tighten to 2,5 ± 0,1 m.daN.
Act on the tensioner roller (24)so as to tension the belt, using a spanner (type FACOM R 161).
Adjust the belt tension, using tool [7]:
- Measuring equipment SEEM CTI 901.1 : 440 ± 15 SEEMunits.
- Measuring equipment SEEM CTG 105.5 : 83 ± 2 SEEMunits.
- Measuring equipment SEEM CTG 105.6 : 88 ± 2 SEEMunits.
WARNING: Never go beyond the tensioner limit.
NOTE:The check of the belt tension is done on the longest belt section between the crankshaft
pinion and the guide roller.

WARNING: Otherwise, restart the operation for positioning the timing belt.
Tighten at least 2 screwsper exhaust camshaft pulley to 1 ± 0,1 m.daN.
Remove the tools [1], [2]and [4].
Rotate the crankshaft 2 turnsin a clockwise direction.
IMPERATIVE: Never turn it back.
Peg the crankshaft, using tool [2].
Peg the camshaft pulleys, using tool [1].
Slacken the nut (23)of the tensioner roller (24).
