Setting the timing   Note When rotating the camshaft, the crankshaft must not be positioned at TDC. Risk of damaging valves and piston crowns.

–  Bring the marking on the camshaft sprocket in line with the marking on the timing belt guard. –  Install the -middle- and bottom part of the timing belt guard. –  Install vibration damper/toothed belt. Tightening torque: 25 Nm.

–  Position crankshaft on TDC cylinder 1. –  Fit timing belt onto tensioning pulley and camshaft sprocket. Tightening the timing belt Conditions l  The engine must be not more than warm to touch. l  Turn the tensioning roller on the eccentric using a nut wrench (e.g. Matra V159) five times in both directions up to the dead stop before tensioning the timing belt. Procedure

–  Tighten the timing belt. Do this by turning the nut wrench (e.g. Matra V159) on the eccentric to the left -direction of the arrow- up to the dead stop. –  Then slacken the timing belt until the notch -1- and the pointer -2- are opposite each other (use a mirror). –  Tighten fixing screws to 20 Nm. –  Position engine on TDC cylinder 1. –  Rotate crankshaft further two revolutions in direction of rotation of engine until engine is again positioned at TDC of cylinder 1. When doing this, it is important that the last 45° (1/8 rotation) are rotated without any interruption. –  Once again inspect the tension of timing belt - specified value: Pointer and notch are positioned opposite to each other. –  Install the top part of the timing belt guard. –  Installing tensioning element for V-ribbed belt. Tightening torque: 25 Nm. –  Install the V-ribbed belt → Chapter.
