K4M, and 862

• Disconnect the upstream oxygen sensor connector (1).
• Unclip the wiring from the upstream oxygen sensor at (2).
• Move the upstream oxygen sensor wiring aside

• Remove:
  • the crankshaft accessories pulley (see 11A, Top and front of engine, Crankshaft accessories pulley: Removal - Refitting, 11A-31),
  • the right-hand suspended engine mounting (see 19D, Engine mounting, Right-hand suspended engine mounting: Removal - Refitting, 19D-22),
  • the upper timing cover bolts,
  • the upper timing cover nuts,
  • the upper timing cover (3),
  • the lower timing cover bolts,
  • the lower timing cover (4).

II - OPERATION FOR REMOVAL OF PART CONCERNED

• Loosen the nut (5) of the timing tensioning roller.

Note: Do not drop the crankshaft timing sprocket when removing the timing belt.

• Remove:
  • the timing fixed roller bolt (6) using the tool (Mot.1368),
  • the timing fixed roller,
  • the timing belt,
  • the timing tensioning roller nut,
  • the timing tensioning roller,
  • the crankshaft timing sprocket.

REFITTING - PROCEDURE 1

I - REFITTING PREPARATION OPERATION

• parts always to be replaced: Timing belt,
• parts always to be replaced: Timing belt tensioning roller,
• parts always to be replaced: Timing fixed roller,
• parts always to be replaced: Crankshaft accessories pulley bolts,
• parts always to be replaced: Inlet camshaft cap,
• parts always to be replaced: Exhaust camshaft cap.

II - REFITTING OPERATION FOR PART CONCERNED

• The first procedure applies to replacing any timing face component which has a crankshaft timing sprocket without a collet and which does not require the exhaust camshaft sprocket or camshaft dephaser to be loosened.

1 - Adjusting the timing

WARNING

Be sure to degrease:

• the end of the crankshaft (timing end),
• the timing sprocket pressure faces and bore of the crankshaft,
• the crankshaft accessories pulley bearing faces,
• the camshaft ends (timing end),
• the camshaft sprocket bores and bearing faces.

This is to avoid timing slippage.

This slippage leads to engine damage.

• Set the camshaft grooves horizontally and below the centre line by turning the camshafts with the (Mot.799-01) if necessary.

• Fit the (Mot. 1496) with the (Mot. 1750) (7).

• Fit:
  • the (Mot. 1496) (8) fitted with the (Mot. 1750) on the end of the camshaft,
  • a lifting eye bolt (9) to secure the tool (Mot. 1496) equipped with the tool (Mot. 1750).

• Check that the mark (10) on the camshaft dephaser is vertical and pointing upwards.
• Make a mark (11) with a pencil between the camshaft dephaser gear and the rocker cover.

2 - Refitting

• Refit a new timing tensioning roller by positioning the lug of the timing tensioning roller in the groove (12).
• Screw on the timing tensioning roller nut without tightening it.

• Refit:
  • the crankshaft timing sprocket (13),
  • a new timing belt,
  • a new timing fixed roller (14).

• Torque tighten the timing fixed roller bolt (50 N.m) (15).

3 - Timing belt tension

• Position the adjustable index (16) opposite the mark (17), by turning the eccentric (18) clockwise using a 6 mm Allen key.
• Torque tighten the timing tensioning roller nut (7 N.m).
• Refit:
  • the tool (Mot. 1489) in the cylinder block,
  • the lower timing cover,
• Tighten to torque the lower timing cover bolts (12 N.m).
• Refit a new crankshaft accessories pulley.

• Use a screwdriver (19) to check that the flywheel does not turn (clockwise at the timing end), otherwise bring the crankshaft back into contact with the tool (Mot. 1489) (20) using the screwdriver; the crankshaft groove should be at the top.
• Torque and angle tighten a new crankshaft accessories pulley bolt (40 N.m + 145
