Assembly overview
  Caution
The crankshaft must not be removed. Just loosening the main bearing caps will cause deformation of the cylinder block bearing pedestals. 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.
