Pay attention to the following notes before installing the camshaft bearing bridges:
Lubricate the camshaft bearings.
Due to tolerance reasons, the camshafts must not be replaced individually.
If the camshaft bearing bridge is damaged, replace th e cylinder head complete with the camshaft bearing
bridge.
It not permitted to reuse the bolts M7 X84; these must always be replaced.
Pay attention to tightening torque, slackening di agram and tightening diagram of the bolts M7x84.

Use wrench bit to tight en cylinder head bolts.
Observe sequence, see tightening pattern.
If the tightening torque is exceeded on a cylinder he ad bolt, unscrew the cylinder head bolt, inspect shank
length of the cylinder head bolt in question (replace bolt if necessary) and tighten again fully, beginning with
