NOTE:
If main bearing replacement is necessary, select
such bearing as to allow proper clearance as
described on p. 3-30 and install it in place.
Between two halves of main bearing, one
side has oil groove. Install this half with oil
groove to cylinder block, and another half
without oil groove to bearing cap.
Make sure that two halves are painted with
same color.
