  Caution
Beware: Aluminium cylinder block! The crankshaft must not be removed. Just loosening the main bearing caps will cause deformation of the crankshaft bearings. This deformation reduces the bearing clearance. Even if the half-bearings are not replaced, changes in the bearing clearance may cause damage.
If the bearing cap bolts are loosened, the cylinder block must be replaced complete with the crankshaft.
Measuring the main bearing clearance is not possible with normal workshop equipment.
  Note
t  For assembly work, the engine must be secured to the Engine support -VAS 6095-.
t  If during repairs to the engine, large quantities of metal shavings and particles produced by wear and abrasion, for example from the bed plate bearings, to avoid further damage derived from this problem, apart from thoroughly cleaning the oil pipes, the oil filter must be replaced.
t  Oil the support and slide surfaces before carrying out assembly work.
