The camshafts of 8-cylinder engines are each located on □ bearings, which come in normal and two repair sizes, so that the camshaft journals can be reground twice. On 6-cylinder engines, the camshafts are located in the camshaft housing. The left camshaft is supported by 5, and the right by 6 bearings (supports).
Camshaft housings are available in standard and two oversize sizes, so the camshaft journals can also be reground twice. Camshaft housings should only be processed systematically when mechanical damage is visible on the rubbing surfaces. The bent camshaft housing is adjusted again by tightening on the cylinder head.
