In addition to checking the lube oil sump level and temperature of a line shaft steady bearing, what else must be checked for?

AI Explanation
The correct answer is B) Ensure free rotation of the oiling ring with the shaft. This is correct because the oiling ring in a line shaft steady bearing must be able to rotate freely with the shaft in order to properly distribute lubricating oil along the bearing surface. If the oiling ring is not able to rotate freely, it will not effectively lubricate the bearing, leading to potential overheating and failure. The other answer choices are incorrect because: A) Checking the gravity head tank overflow sight glass is not directly related to the condition of the line shaft steady bearing. C) The oiling ring should rotate with the shaft, not remain stationary. D) Checking the lube oil pump discharge pressure is not a specific requirement for line shaft steady bearing maintenance.
