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.
Refit the screw (2).
