Cayenne Titanium (9PA) V8-4.5L (2006)
The rolling direction of the timing chain must always be the same.
If the timing chain is to be reused, the rolling direction of the timing chain must be marked before it is removed.
Information:
If the timing chain has to be removed or replaced, check the guide and tensioning rails as well as the chain pinions for wear and scoring and replace
them if necessary.
Camshaft timing gears and camshaft adjusters must be installed and it must be possible to turn them.
1. Place timing chain loosely on all sprockets. Ensure that the timing chain is in the correct position on the guide rails.
2. Fit guide and tensioning rails.
3. Place guide rails between the camshafts on the threaded pegs. To do this, let timing chain dangle between the camshafts.
