(6 CYLINDER)
Main bearings for the 6 cylinder engines are fur-
nished in standard size and .001", .002", .010" and
.012" undersizes.
Bearing upper and lower halves are interchange-
able. However bearing No. 1 is not interchangeable
with No. 2, 3 or 4. Bearing shells are stamped with
the part number or size. Bearings should be replaced
in pairs; never use a new bearing half with an old
bearing half.
CAUTION: No. 2 and No. 3 bearing caps can be
reversed in error. Always place punch marks on
the caps and the block before removal to insure
proper installation
