have been fitted, apply a light coat of
engine oil to the journals and bearings.
25.
Tum the crankshaft throw to the
bottom of its
stroke.
Push the piston all
the way down until the rod bearing seats
on the crankshaft journal.
26.
Install the connecting rod cap.
Torque the nuts to specifications.
27. After the piston and connecting
rod assemblies have been installed, check
the side clearance between the connecting
rods on each connecting rod crankshaft
journal
(Fig.
33).
28.
Clean the oil pan, oil pump and
oil pump
screen.
Prime the oil pump by
filling either the inlet or outlet port with
ellline oil and rotating the pump shaft to

CAMSHAFT BEARING
Camshaft
bearings
are
available
pre-fmlshed to size for standard and
0.015-inch undersize journal
diameters.
The bearings are not interchangeable from
one bore to
another.

3. Select the proper size expanding
collet and back-up nut and assemble on
the
expanding
mandrel.
With
the
expanding collet collapsed, install the
collet assembly in the camshaft bearing,
and tighten the back-up nut on the
expanding mandrel until the collet fits the
camshaft bearing.
4. Assemble the puller screw and
extension
(If
necessary) as shown and
install on the expanding mandrel. Wrap a
cloth around the threads of the puller
screw to protect the front bearing or
journal. Tighten the pulling nut against the
thrust bearing and pulling plate to remove
the camshaft bearing. Be sure to hold a
wrench on the end of the puller screw to
prevent it from turning.
5. Repeat the procedure for each
bearing. To remove the front bearing,
install the puller screw from the rear of
the cylinder block.
INSTALLATION
1. Position the new bearings at the
bearing bores with the oil holes aligned,
and press them In place with the tool
shown In Fig. 45. Be sure to center the
pulling plate and puller screw to avoid
damage to the bearing. Failure to use the
co""t expanding collet
can
cauae aewre
bearing damap. Be sure the front
bearlnJ
is
installed the
specified
distance below
the front face of the cylinder block
(Fia-
49).
2. Install the core plug.
