Bearings from an engine are being inspected. It is observed that the most wear starts at the furthest point away from the location of the oil pump and is noticeable less as you get closer to the pump. Technician A says that could be due to a condition known as dry starts. Technician B says that this is most likely due to incorrect drive belt tension. Who is correct?

Question

Quizplus · Accepted Answer

Dry starts occur when there is insufficient lubrication in the engine during startup, which can cause wear on the bearings farthest from the oil pump. Incorrect drive belt tension would not be a factor in this type of wear pattern. Therefore, Technician A is correct but Technician B is not.
