1997 Ford Ranger Remove Harmonic Balancer
The harmonic balancer, or crankshaft damper, on the 1997 Ford Ranger is attached to the crankshaft. It keeps the crankshaft vibrations at a minimum, which reduces excessive vibration in the engine and allows the crankshaft pulley to rotate smoothly. The crankshaft pulley turns the accessory drive belts, and smooth operation is necessary for the life of the engine and the accessories.
