INSTALLATION

NOTE: Assemble the timing chain, crankshaft sprocket and camshaft sprocket with the timing marks aligned Fig. 5.

1. Apply Mopar (TM) Silicone Rubber Adhesive Sealant to the keyway in the crankshaft and insert the key With the key in the keyway on the crankshaft, install the assembly on the crankshaft and camshaft.

Fig. 6 Camshaft Sprocket Preload Bolt:

2. Install the camshaft sprocket retaining preload bolt and washer Fig. 6. Tighten the preload bolt to 108 N.m (80 ft. lbs.) torque.

Fig. 7 Verify Sprocket/Chain Installation - Typical:

3. To verify correct installation of the timing chain, turn the crankshaft to position the camshaft sprocket timing mark as shown in Fig. 7. Count the number of chain pins between the timing marks of both sprockets. There must be 15 pins.

NOTE: Installation of the timing chain with the timing marks on the crankshaft and camshaft sprockets properly aligned ensures correct valve timing. A worn or stretched timing chain will adversely affect valve timing. If the timing chain deflects more than 12.7 mm (1/2 inch) replace it. The correct timing chain has 48 pins. A chain with more than 48 pins will cause excessive slack.

4. Install the crankshaft oil slinger.
5. Replace the oil seal in the timing case cover.
6. Lubricate the tension spring, thrust pin and pin bore in the preload bolt with Mopar (TM) Engine Oil Supplement, or equivalent. Install the spring and thrust pin in the preload bolt head Fig. 6.

Fig. 2 Timing Case Cover Components:

7. Install the timing case cover and gasket.
8. With the key installed in the crankshaft keyway, install the vibration damper, washer and bolt. Lubricate and tighten the bolt to 108 N.m (80 ft. lbs.) torque.
9. Install the serpentine drive belt and tighten to the specified tension, Refer to Engine/Drive Belts, Mounts, Brackets and Accessories/Drive Belt/Service and Repair for the proper procedure.
10. Install the fan and hub (or Temporal fan) assembly. Install the shroud.
11. Connect negative cable to battery
