Any excess oil that did not drain out of the drain plug may leak out here. Be prepared with a shop rag or shop towel to catch any drips.

Insert a flathead screwdriver into one of the side gaps between the crankcase cover and the crankcase.

Twist the screwdriver to begin to pull the crankcase cover away from the crankcase.

Repeat for the opposite side gap, and repeat until the crankcase cover comes loose from the crankcase.

During reassembly, check that the crankcase cover O-ring is in good condition, and replace it if it is cracked or deformed.
