NOTES ON INSTALLING CAMSHAFT BEARING BRIDGE - AH05.20-P-2000-01AV

Engines 112, 113 except 113.960, 113.960 except cylinder shutoff codes 479, 113.962/982/993, 112.951/976

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 the cylinder head complete with the camshaft bearing
