Refitting.
Fit the (new) timing belt in position, in the following order:
Inlet camshaft pulley, exhaust camshaft pulley, guide roller, crankshaft pulley, position tool [5],
coolant pump pulley, dynamic tensioner roller.
Remove tools [1], [2a], [2b] and [4].
Overtension on the belt.
Turn the tensioner roller (7) with the aid of a hexagonal spanner at «a».
Bring the index «c» to position «d», to tension the belt to the maximum of the interval indicated.
Hold the tensioner roller, using tool [4].
Tighten the fixing nut of the tensioner roller, tightening to 1 m.daN.
Turn the crankshaft by 4 rotations (normal direction of rotation).
IMPERATIVE: Never make the crankshaft rotate backwards.
Make sure that the timing is correctly set by refitting the pegs [1], [2a] and [2b].
