Selection of Bearing Shell
Selection of main bearing shell
1. Selection of crankshaft main bearing upper shell.
Related letter marks are available on the cylinder block
(consisting of "A" and "B"). Such as "BBBBA" in the
illustration, each letter from left to right is for one type of
crankshaft bearing upper shell. The first letter "B" is for
the upper shell type of crankshaft main bearing first
journal, and so on; the fifth letter "A" is for the upper shell
type of crankshaft main bearing fifth journal.
2. Selection of crankshaft main bearing lower shell.
Related marks are available on the first balancer at the
front end of crankshaft (consisting of "A" and "B"). Such
as "AAABB" on the first crankshaft front end balancer
shown in the illustration, the first letter "A" is for the lower
shell type of crankshaft main bearing first journal, and so
on; the fifth letter "B" is for the lower shell type of
crankshaft main bearing fifth journal.
3. Precautions for crankshaft main bearing shell assembly:
a. There is shell groove and oil hole on the main bearing upper shell, and the oil hole should be aligned
with that on the engine block, but the main bearing lower shell has no oil hole.
b. Apply a coat of engine oil to the inner surface of main bearing shell before installation. The back side of
bearing shell should be clean without any oil or foreign matter during assembly.
