Setting the timing.
Remove the upper timing cover (1).
Rotate the engine by means of the crankshaft screw (2).
NOTE:The pegging hole is located under the crankshaft bearing cap cover.
Peg the engine flywheel, using tool [3].
Remove the lower timing cover (3).
Uncouple the exhaust line from the manifold.
IMPERATIVE: Uncouple the exhaust line in order to avoid damaging the front flexible pipe. Twisting,
pulling and bending the front flexible pipe reduces its life.
Remove:
- The engine speed sensor (6).
- The belt retaining stop (5).
- The screw (2).
- The crankshaft pinion (4)
(with its magnetic track «a»).
IMPERATIVE: The magnetic track should show no signs of damage and should not be approached
by any other source of magnetism. Should this not be adhered to, it is essential to replace the
crankshaft pinion.
