TIMING BELT/CHAIN AND SPROCKETS (Continued)
INSTALLATION
The chain drive system is equipped with a timing
chain tensioner which reduces noise and prolongs
timing chain life. In addition, it compensates for
wear and temperature changes on the valve train for
proper engine operation.
(1) Turn the tensioner lever to the unlocked (down)
position (Fig. 84).
(2) Pull the tensioner block toward the tensioner
lever to compress the spring. Hold the block and turn
the tensioner lever to the lock position (Fig. 84).

(3) Apply Mopar Silicone Rubber Adhesive Seal-
ant to the keyway in the crankshaft and insert the
key. With the key in the crankshaft keyway, install
the crankshaft, camshaft sprockets and timing chain.
Ensure the timing marks on the sprockets are prop-
erly aligned (Fig. 82).
(4) Install the camshaft sprocket retaining bolt
and washer. Tighten the bolt to 108 N·m (80 ft. lbs.)
torque.
(5) To verify correct installation of the timing
chain, turn the crankshaft to position the camshaft
sprocket timing mark as shown in (Fig. 85). Count
the number of chain pins between the timing marks
of both sprockets. There must be 20 pins.
