3.19 Camshaft Sprocket – MY06 Update
CAUTION
Setting the camshaft timing is required
whenever the camshaft drive system is
disturbed to ensure the relationship between
any chain and sprocket is not lost. Even when
only one sprocket is involved, multiple
crankshaft rotations will not produce
conditions where correct timing can be
confirmed.
If required, follow the Left-hand Secondary
Camshaft Chain Components reinstallation
procedure to reset the camshaft timing.
Remove
Right-hand Side
