Cylinder block (pulley end)
  Caution
The crankshaft must not be removed. Even loosening the main bearing caps will cause deformation of the cylinder block bearing seats. This deformation will cause a reduction of the bearing clearance. Even if the bearing shells are not renewed bearing damage could occur due to a different bearing clearance.
If the bearing cap bolts are loosened, the cylinder block must be renewed complete with the crankshaft.
Measuring the main bearing clearance is not possible with normal workshop equipment.
  Note
t  If large quantities of metal chips and abraded material are found, e.g. caused by fretting damage, then clean oil channels and renew oil filter in order to prevent this causing further damage.
t  All bearing and running surfaces must be oiled before assembly.
t  Secure engine to engine and gearbox support -VAS 6095- to carry out repairs.
