Camshaft: Procedures
Setting Camshaft Timing
Setting Camshaft Timing
NOTE: Setting the camshaft timing is necessary whenever the camshaft drive system has been disturbed such that the relationship between any chain
and sprocket has been lost. Even when only one sprocket is involved, multiple crankshaft rotations will not produce conditions where correct timing
can be confirmed.
Follow the left bank secondary camshaft drive chain replacement procedures to reset the camshaft timing.
