The upper bearings have three holes in them. The middle hole
receives
oil
from
the main oil rifle. One of the adjacent holes is
aligned
with
a drilling to the camshaft journal and
serves
as an
orifice for lubrication
flow
to the journal. The other adjacent
hole supplies oil for piston cooling. The hole does not align
perfectly
with
the cooling nozzle. The hole is off-set to keep the
nozzle
from
dropping
into
the crankshaft oil supply
passage.
Note:
Oversize service main bearings are available for re-
ground crankshafts.
