Technician A is correct in describing "spread" as the feature where the distance across the outside parting surface of the bearing is slightly greater than the diameter of the housing bore. Technician B is correct in describing "bearing crush" as the condition when the bearing edges extend slightly from the seat upon installation. Both terms are important for ensuring the bearing stays securely in place within its housing.
