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. |
| The pistons must not be removed. |
