Starting the crankshaft main bearing repair requires the removal of the
Oil Pan according to service protocols. The inspection of crankshaft main bearings requires single set replacement because improper installation procedures could result in engine damage. The first task is to uninstall one main bearing cap and then proceed with removing the crankshaft main bearings. The new bearings need installation with lubrication from either Super Premium SAE 5W-30 Motor Oil XO-5W30-QSP or WSS-M2C153-G specification equivalent products since Ford designates the crankshaft main bearings for precision fitting. You must install the crankshaft main bearing before putting the main bearing cap in place and continue this installation sequence for each crankshaft main bearing. Finally, reinstall the oil pan.
