position of TDC pin before setting point

position of TDC pin setting point

• Insert the TDC setting pin (Mot. 1054) and rotate the engine slightly clockwise (timing end) until the setting point is reached.

• At the setting point the camshaft grooves must be horizontal and offset below the centre line.

• Fit the (Mot. 1496) onto the ends of the camshafts.
• Remove:
  • the crankshaft accessories pulley bolt,
  • the crankshaft accessories pulley.

2 - REMOVING THE TIMING BELT

WARNING

Never turn the engine against its operating direction.

WARNING

The belt must be replaced with a new one if it has been removed.

WARNING

When replacing the belt, be sure to replace the tensioning rollers and fixed rollers.

Note: Always replace the inlet camshaft dephaser bolt and the exhaust camshaft pulley nut after checking the tension of the timing belt.

• Slacken the timing belt by undoing the tensioning roller nut (4).
• Remove:
  • the fixed roller (5) fitted with its bolt and spacer,
  • the timing belt,
  • the tensioning roller (6) fitted with its nut,
  • the crankshaft sprocket (7),
• Check that the ring of the camshaft dephaser is correctly locked (no rotation of the ring to the left or to the right); if it is not, replace the inlet camshaft dephaser.

Note: If the inlet camshaft dephaser must be removed, follow the removal-refitting procedure for the camshaft dephaser (see 11A, Top and front of engine, Camshaft: Removal - Refitting, 11A-247). Always lock the inlet camshaft dephaser when replacing it.

REFITTING

I - OPERATION FOR REFITTING THE TIMING BELT

1 - ADJUSTING THE TIMING

• Check that camshaft setting tool (Mot. 1496) is still in place.

position of TDC pin setting point

• Check that the TDC pin (Mot. 1054) is still in place and that the crankshaft is set.

WARNING

Always degrease:

• the end of the crankshaft (timing end),
• the timing sprocket bore and contact surfaces,
• the bearing faces of the crankshaft accessories pulley.

This is to avoid timing slippage.

This slippage causes engine damage.

2 - TIMING BELT REFITTING PREPARATION OPERATION

• Fit:
  • the (Mot. 1801) fitted with the sprocket (Mot. 1509- 01),
  • the upper bolt (8) on the upper timing cover and the collar nut (9).
• Tighten the upper bolt on the upper timing cover and the collar nut.
• Bring the toothed sprockets of the tool into contact with the camshaft pulleys.
• Torque tighten the toothed sprocket nuts (80 N.m) (10).

Note: Beware of oil running out when removing the blanking cover from the camshaft dephaser and when removing the camshaft dephaser.

• Remove the inlet camshaft dephaser blanking cover (11).

• Release by a single turn:
  • the old inlet camshaft dephaser bolt (12),
  • the old exhaust camshaft pulley nut (13).
• Remove the (Mot. 1801) fitted with sprocket (Mot.1509-01).

3 - REFITTING THE TIMING BELT

WARNING

Never turn the engine against its operating direction.

WARNING

The belt must be replaced with a new one if it has been removed.

WARNING

When replacing the belt, be sure to replace the tensioning rollers and fixed rollers.

Note: Always replace the inlet camshaft dephaser bolt and the exhaust camshaft pulley nut after checking the tension of the timing belt.

• Refit:
  • the timing sprocket on the crankshaft,
  • the new tensioning roller.

Note: Ensure that the (Mot. 1496) is correctly fitted and that the inlet camshaft dephaser and the exhaust camshaft pulley can rotate freely so that the timing belt tension is correct.

• Refit:
  • the new timing belt,
  • the new fixed roller.
