This harmonic balance puller set is designed for removing harmonic balancers, gear pulleys, steering wheels and flywheels. The four slots in the yoke allow for application using 2 or 3 holes. The center screw is equipped with a floating swivel, which prevents damage to the shaft end. Made of drop-forged and heat-treated steel, this tool set is very durable. The kit is delivered in a blow molded case for easy storage and transport.
