4. Ensure that the parent bores for the bearing shells
in the cylinder block are clean. Ensure that the
threads for the main bearing bolts in the cylinder
block are clean and free from damage.
5. Clean the main bearing shells and the thrust
washers. Inspect the main bearing shells and the
thrust washers for wear or damage. If necessary,
replace the main bearing shells and the thrust
washers.
Note: If the main bearing shells are replaced, check
whether oversize main bearing shells were previously
installed. If the thrust washers are replaced, check
