Drain the lubricating oil and remove the lubricating oil pan.
NOTE: Before removing the main bearing caps, make certain that the caps are clearly marked for their location on the
lubricating oil cooler side of the main bearing cap.
Perform a visual inspection of the main bearings and crankshaft journals. Remove the No. 2 and 3 caps and
check the crankshaft journals for signs of overheat, deep scratches or other damage. If there is no damage, there
is no need to pull the other main bearing caps at this time.
Inspect the main bearing caps for dents, cracks, or other damage.
Inspect the crankshaft journals for deep scratches, indications of overheating and other damage.
NOTE: If the crankshaft journals or main caps are damaged, the engine will need to be removed to complete the overhaul.
