| 1.: The crankshaft must not be disassembled. Even loosening the crankshaft bearing cover nuts can cause deformations.
of the cylinder block. These deformations reduce the bearing clearance. Even if the bearing shells are not replaced,
Bearing damage can be caused by a changed bearing clearance.
If the cylinder head nuts have been loosened, the entire cylinder block must be replaced with the crankshaft. |
