Fig. Fig. 3: Use the special tool to hold the pulley while loosening the center bolt-Premier and Monaco

  1. A thread lock is applied to the crankshaft pulley nut. Use a brass hammer and strike the nut prior to loosening.
  2.  
  3. Using the special tool C-3281 or equivalent to hold the crankshaft pulley while loosening the crankshaft retaining nut.
  4.  
  5. Rotate the crankshaft so that the keyway points up. This will prevent the key from falling into the oil pan. Remove the retaining nut and crankshaft pulley.
  6.  
  7. Use a small prytool to carefully pry the seal out of the cover taking care not to damage the seal locating bore.
  8.  

To install:
  1. Lightly oil the new oil seal inside lip and install it into the front timing chain cover using special tool 6077 or equivalent.
  2.  
  3. Install the crankshaft pulley to the crankshaft making sure to align the slot in the pulley with the key on the crankshaft. Apply Loctite 271® to the threads of the crankshaft pulley nut. Tighten the center pulley retaining nut to 133 ft. lbs. (180 Nm) by using the special tool C-3281 to once again hold the pulley stable.

  1. Remove the center crankshaft bolt. It may be necessary to hold the engine to keep it from turning while loosening the center bolt, this can be done by having an assistant hold the flywheel stable with a wrench, a breaker bar or even a C-clamp.
  2.  
  3. Using a suitable torsional crankshaft damper removal/installation tool (bolt-on type), remove the torsional damper from the crankshaft. If access to the torsional damper is restricted, removal of the A/C compressor is possible, just make certain to move the compressor aside without removing the refrigerant hoses from it.
  4.  
  5. After the torsional damper has been removed, make certain to locate the crankshaft key. This will be needed upon installation.

To install:
  1. Install the crankshaft key into the groove on the crankshaft.
  2.  
  3. Install the torsional damper onto the crankshaft after aligning the slot in the damper with the key on the crankshaft. Lightly tap the damper onto the crankshaft with a rubber or plastic mallet. Tap the center of the damper, not the outer edges.
  4.  
  5. After the damper has been installed slightly onto the crankshaft, install the center bolt and slowly tighten the bolt until the torsional damper seats itself completely onto the crankshaft.
  6.  
  7. Tighten the center bolt to 112 ft. lbs. (151 Nm) while your assistant is holding the engine from turning.
  8.  
  9. Slide the two pulleys back onto the crankshaft and secure in place with the six attaching bolts. Tighten the six bolts until evenly snug.
  10.  
  11. If the A/C compressor was moved aside for ease of access, install it back onto the engine block.
  12.  
  13. Install the right inner splash shield in the wheel well.
  14.  
  15. Lower the vehicle to the ground.
  16.  
  17. Install the serpentine and A/C drive belts. Refer to General Information & Maintenance for the procedures on tightening the drive belts for correct tension.
