Tools Required

1. Remove the drive belt. Refer to Drive Belt Replacement .

Important: If only replacing the crankshaft pulley, do not remove the fan shroud and the engine cooling fan.

2. Remove the fan shroud. Refer to Fan Shroud Replacement in Engine Cooling.
3. Remove the engine cooling fan. Refer to Fan Clutch Replacement in Engine Cooling.



4. Raise the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
5. Remove the crankshaft pulley bolts.
6. Remove the hub bolt and washer from the crankshaft pulley.
7. Remove the crankshaft pulley.




Notice: To prevent damage to the end of the crankshaft when using a crankshaft balancer removal tool install a bolt in the crankshaft. Use a shorter bolt with the same threads as the crankshaft balancer bolt. This bolt will allow a place for the tool to push against. The shorter bolt is to keep from going past the threads in the crankshaft and damaging the crankshaft threads.

8. Position the J 24420-B puller tool onto the crankshaft hub.



9. Turn the center puller screw clockwise in order to remove the hub from the crankshaft.
10. Inspect the crankshaft hub for damage.

Replace if necessary.

11. Remove the key from the crankshaft.
12. Inspect the crankshaft key for damage.

Replace if necessary.

1. Coat the engine front cover seal contact area with engine oil.



2. Apply RTV sealer to the keyway on the crankshaft.
3. Install the key into the keyway on the crankshaft.



4. Install the pulley hub into position over the key on the crankshaft.



5. Install the J 29113 through the hub and into the crankshaft so that at least 6 mm (0.24 in) of threads are engaged.
6. Pull the crankshaft pulley hub into position against the J 29113 .
7. Remove the J 29113 from the crankshaft.
8. Make sure that the hub is seated against the crankshaft.



9. Position the crankshaft pulley over the crankshaft pulley hub.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

10. Install the crankshaft pulley bolts and the hub bolt and washer.

Tighten

•	Tighten the crankshaft pulley bolts to 50 N·m (37 lb ft).

•	Tighten the crankshaft pulley to hub bolt to 105 N·m (77 lb ft).

11. Lower the vehicle.
12. Install the engine cooling fan. Refer to Fan Clutch Replacement in Engine Cooling.
13. Install the fan shroud. Refer to Fan Shroud Replacement in Engine Cooling.
14. Install the drive belt. Refer to Drive Belt Replacement .
