Hi all, I have a 1996 xplorer 400 and I have to remove the right side cover that houses the water pump. I have the motor on the bench and the case loose and broke apart but I need to know about the center where the crank comes through the case. Is there just a oil seal on the crank? The case does not want to let go around the crankshaft. Should I just pry it apart or is there another way to get it to give? Thanks all.
