Directions for How to Install a Harmonic Balancer

The harmonic balancer, also known as a harmonic or crank pulley damper, lessens the vibration of your engine. It is located at the front of the engine on the crank shaft. Replacement of the harmonic balancer can be time consuming and tricky.

Procedures:
1. Disconnect the negative battery cable, placing it safely against the battery. Drain the radiator into a large bucket; do not drain on the ground if you use coolant.
2. Remove the belts, radiator hose, fan shroud and other items that may be in the way. Mark any wires that may be in the way for correct placement later.
3. Remove the harmonic balancer bolt, then gently pull the harmonic balancer from the crankshaft using the Special Tool 8513A insert and the jaw puller. Clean the damper bore and crankshaft nose thoroughly.
4. Slide the harmonic balancer on the crankshaft nose gently and ensure it is on as far as you can push it by hand. Press the harmonic balancer onto the crankshaft with the Special Tool 8512-A.
5. Install the harmonic balancer bolt, using the torque wrench to tighten to 176 N·m or 129 ft. lbs. Replace the belts, radiator hose, fan shroud and other items if removed. Refill the radiator. Connect the battery cable.
