REMOVAL - TIMING CHAIN AND CAMSHAFT
SPROCKET
(1) Disconnect negative cable from battery.
(2) Remove the timing chain cover. (Refer to 9 -
ENGINE/VALVE TIMING/TIMING BELT / CHAIN
COVER(S) - REMOVAL)
(3) Rotate engine by turning crankshaft until the
timing marks are aligned as shown in (Fig. 156).
(4) Remove camshaft sprocket attaching bolt.
(5) Remove the timing chain with camshaft
sprocket.
(6) Remove the crankshaft sprocket. (Refer to 9 -
ENGINE/VALVE TIMING/TIMING BELT/CHAIN
AND SPROCKETS - REMOVAL)
REMOVAL - CRANKSHAFT SPROCKET
(1) Remove the timing chain. (Refer to 9 -
ENGINE/VALVE TIMING/TIMING BELT/CHAIN
AND SPROCKETS - REMOVAL)
(2) Using Special Tools 8539, 5048-6, and 5048-1,
remove the crankshaft sprocket while holding the
crankshaft from turning (Fig. 157). Be careful not to
damage the crankshaft surfaces.
INSPECTION
(1) Position a scale next to timing chain so that
any movement of chain may be measured.
(2) Position a torque wrench and socket on the
camshaft sprocket attaching bolt. Apply force in the
direction of crankshaft rotation to take up slack to
the following torque:
²41 N´m (30 ft. lb.) with cylinder heads installed
²20 N´m (15 ft. lb.) with cylinder heads removed

NOTE: With torque applied to the camshaft
sprocket bolt, crankshaft should not be permitted to
move. It may be necessary to block crankshaft to
prevent rotation.
(3) Holding a measuring scale along edge of chain
links (Fig. 158).
(4) Apply force in the reverse direction to the fol-
lowing torque:
²41 N´m (30 ft. lb.) with cylinder heads installed
²20 N´m (15 ft. lb.) with cylinder heads removed
(5) Measure amount of sprocket/chain movement.
(6) Install a new timing chain and sprockets if
movement exceeds 3.175 mm (1/8 in.). (Refer to 9 -
ENGINE/VALVE TIMING/TIMING BELT/CHAIN
AND SPROCKETS - REMOVAL)
INSTALLATION - TIMING CHAIN AND
CAMSHAFT SPROCKET
(1) Rotate crankshaft so the timing arrow is to the
12 o'clock position (Fig. 156).
NOTE: Lubricate timing chain and sprockets with
clean engine oil before installation.
(2) While holding camshaft sprocket and chain in
hand, place timing chain around the sprocket, align-
ing the plated link with the dot on the sprocket. Posi-
tion the timing arrow to the 6 o'clock position (Fig.
156).
(3) Place timing chain around crankshaft sprocket
with the plated link lined up with the dot on the
sprocket. Install camshaft sprocket into position.
(4) Use a straight edge to check alignment of tim-
ing marks.
(5) Install camshaft sprocket bolt and washer.
Tighten bolt to 54 N´m (40 ft. lbs.).
