(1) This Tooling is available for rotating the engine.
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Note: The bearing has a locating tab. When the bearing is viewed from the flywheel, counterclockwise rotation is required for the installation of the upper half of the bearing. Ensure that the tab is properly seated in the groove. Ensure that the tab does not break in the groove.Note: If the main bearing cap bolts were removed, use a tap in order to clean the threads in the cylinder block prior to the installation of the bolts. Tighten the bolts to a torque of 100 20 N m (75 15 lb ft).
