Install the Bearings-Start with the front
or rear bearing and work toward the center
from the opposite end of the block.
When you finish installing the center
bearing, install the -remaining two bearings
by working from the opposite end. The
reason is, the farther you are from the
bearing-relative to its position in the
block-the more accurate the installation
tool can be lined up with the centerline
of the cam-bearing bore regardless of
whether it's self-centering or not. You'll
have the bores at the opposite end of the
block from the bearing you're installing
to use as a reference to line up the
bearing.
To install a bearing, select the one
which fits the location you want to start
with. Although obvious, most bearing
manufacturers list bearing locations with
each part number on the box. Cross-reference
these numbers with those on the
back-side of the bearing insert to confirm
their locations. This is also a good check
to make sure you have the right bearings.
I once got a Buick V-6 bearing mixed in
with four 351C bearings!
Begin installing the first bearing insert
by slipping it over the mandrel. If you
have the expansion-type mandrel, you'll
have to expand it so it fits snugly in the
ID of the bearing. With the solid type,
select one that fits the bearing ID. Wrap
some masking tape around the mandrel if
it's a little loose. Also apply some oil to
the mandrel.
With the pull or drive rod handy, position
the bearing and mandrel over the
bearing bore so the oil hole/s in the insert
line up with those in the block-so they
will line up after the bearing is installed.
Use sealer on the cam plug. It seals oil and
is considerably more difficult to get to with
the engine in place, so a leaky cam plug
presents a big problem once the engine is
installed. This engine is fully assembled
because an engine stand was used to support
it during its assembly making it
impossible to install the cam plug. You'll
have the same problem if you use a stand,
so don't forget the cam plug.
