Built from heat-treated steel with galvanized nuts, an aluminum washer, and a thrust bearing, the set is sized to thread into the crank, then draw the balancer on evenly as you turn the nut. The result is faster, safer assembly and reduced risk of damage to the crank snout or balancer hub.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this tool simplify installing a harmonic balancer?\u003c\/h3\u003e\n\u003cp\u003eThe kit uses a threaded rod that screws into the crankshaft and a nut that pulls the balancer onto the crank in a straight, controlled motion. The included thrust bearing reduces friction so the balancer slides on smoothly without binding or scoring.
