Remove the bearing caps, cap side bearings, and
thrust metals. Place each thrust metal with
identification of the position and direction.
Carefully install each thrust metal so that the
grooved one is positioned away from the cap.
Do not confuse the upper and lower main bearing
metals. The upper main bearing metal (block
side) has an oil hole, and the lower one does not.
The “wheel and arrow” marks on the cap shall
face the flywheel.
