REMOVAL AND INSTALLATION (Continued)
INSTALLATION
(1) Lubricate camshaft journals with clean engine
oil.
NOTE: Position the right side camshaft so that the
camshaft sprocket dowel is near the 10 o'clock
position, This will place the camshaft at the neutral
position easing the installation of the camshaft
bearing caps.
(2) Position the camshaft into the cylinder head.
(3) Install the camshaft bearing caps, hand tighten
the retaining bolts.
(4) Working in 1/2 turn increments, tighten the
bearing cap retaining bolts starting with the middle
cap working outward (Fig. 100).

Sequence
(5) Torque the camshaft bearing cap retaining
bolts to 11 N·m (100 in. lbs.).
(6) Position the camshaft drive gear into the tim-
ing chain aligning the V8 mark between the two
marked chain links (Two links marked during
removal) (Fig. 101).
(7) Using the adjustable pliers, rotate the cam-
shaft until the camshaft sprocket dowel is aligned
with the slot in the camshaft sprocket. Install the
sprocket onto the camshaft (Fig. 102).
CAUTION: Remove
sprocket bolt. Failure to do so can cause bolt over-
torque resulting in bolt failure.
excess oil from camshaft
(8) Remove excess oil from camshaft sprocket bolt,
then install the camshaft sprocket retaining bolt and
hand tighten.
(9) Remove timing chain wedge special tool 8350
(Fig. 97).
(10) Using Special Tool 6958 spanner wrench with
adapter pins 8346 (Fig. 103), torque the camshaft
sprocket retaining bolt to 122 N·m (90 ft. lbs.).
(11) Install the camshaft position sensor (Fig. 98).
(12) Install the cylinder head cover.
CRANKSHAFT MAIN BEARINGS
CRANKSHAFT MAIN BEARING SELECTION
The main bearings are "select fit" to achieve proper
oil clearances. For main bearing selection, the crank-
shaft position sensor target wheel has grade identifi-
cation marks stamped into it (Fig. 104). These marks
are read from left to right, corresponding with jour-
nal number 1, 2, 3, 4 and 5. The crankshaft position
sensor target wheel is mounted to the number 8
counter weight on the crankshaft.
NOTE: Service main bearings color coded. These
color codes identify what size (grade) the bearing
is.
CHECKING CRANKSHAFT END PLAY
(1) Mount a dial indicator to a stationary point at
front of engine. Locate the probe perpendicular
against nose of crankshaft (Fig. 105).
(2) Move the crankshaft all the way to the rear of
it's travel.
(3) Zero the dial indicator.
(4) Move the crankshaft all the way to the front of
it's travel and read the dial indicator. Refer to Crank-
shaft End Play Specification Chart.
