- If fitting a new camshaft dephaser, check that it is
locked by following the procedure described below.
- Fit a stud to the camshaft dephaser hub and tighten
it.
- Place the camshaft dephaser in a vice fitted with
jaws.
- Mechanically lock the camshaft dephaser by rotating

spanner.
- Check that the camshaft dephaser is correctly
locked (no rotation of the hub in relation to the wheel
to the left or right).
- If there is a rotation of the hub in relation to the
wheel, the camshaft dephaser is faulty and must be
replaced.
- Degrease the end of the inlet camshaft (timing end)
and clean the bores and bearing faces of the camshaft
