This procedure must only be used to remove and install the main bearing shells with the crankshaft in position.The removal procedure and the installation procedure must be completed for each pair of main bearing shells before the next pair of main bearing shells are removed.
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Ensure that the main bearing shells are clean and free from wear and damage. If necessary, replace the main bearing shells. Note: If the main bearing shells are replaced, check whether oversize main bearing shells were previously installed. If the thrust washers are replaced, check whether oversize thrust washers were previously installed.
