NOTE
To check for proper clearance of oil pump bushing, grasp tang of oil
pump shaft with a pair of pliers and try to move it in or out. If any end
play can be felt, bushing is not properly positioned and there is too much
clearance. If no axial movement is felt and if oil pump shaft rotates
freely without binding, position of oil pump bushing is correct.
