Answer: technician B
Explanation:
The oil is picked up from the oil pump though a pick up tube that is mounted on the oil pump. The end of the pick up tube sits in the oil at the bottom of the oil pan. The oil is then forced through holes that are drilled into the block. Those holes which are called (journals) lead to the main bearings,rod bearings,lifters, camshaft, ect..
Technician B says that lubrication to the main bearings is fed through the main oil gallery in the block is correct.
How are the main bearings lubricated?
Lubrication regimes
Engine bearings are lubricated by motor oils constantly supplied in sufficient amounts to the bearings surfaces. Lubricated friction is characterized by the presence of a thin film of the pressurized lubricant (squeeze film) between the surfaces of the bearing and the journal.
Which lubricant is used for bearing?
A lithium-based grease, whose base oil is mineral oil, is commonly used as a lubricant for rolling bearings, as it is compatible with the working surface of the bearing. Its operating temperature range is -30˚C to 130˚C.
