[Disassemble]
• Remove the bearing caps, cap side bearings, and
thrust metals. Place each thrust metal with identifica-
tion of the position and direction.
The position number of reassembling is punched on
a metal cap (except for both ends) and a cylinder
block.
[Reassemble]
• 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
"arrow" marks on the cap shall face the flywheel.
