Harmonic balancer/damper - How to remove and install

| − | + | =Overview= | |
| + | The harmonic balancer or damper is usually a tight press-fit onto the end of the crankshaft. This is so the torsional vibrations of the crankshaft generated by the power pulses of the engine can be transmitted to- and absorbed or dissipated by- the harmonic balancer. If the fit isn't tight, the harmonic balancer will not be able to absorb the vibrations and in some cases this can lead to a failure of the key/keyway that locates the balancer and/or the fastener that secures it to the crankshaft along with the tight press-fit. | ||
| + | =Tools= | ||
| + | It is always advisable to use a dedicated tool for damper removal. To do otherwise risks damaging the damper beyond repair, damaging the crankshaft or other related parts and covers, or personal injury. Because of how tightly most dampers are pressed onto the crank, there's basically no way a damper could be pried off anyway. Heat cannot be used because there could be damage to the damper oil seal. Also most dampers have an elastomeric band that separated the inner hub from the outer inertia ring. Heat can ruin the bond between the two, causing catastrophic failure of the damper that could damage the radiator, water pump, front mounted accessories, the hood, could possibly sever engine oil or ATF cooler lines, radiator hoses, etc. | ||

| + | While there are cheap pullers available that are usually good for a couple uses before it strips out or bends, unless this is a one-time repair and it's not anticipated to ever be done a second time it's always a good idea to invest in a quality tool that's made to last. | ||
