289 Budget Build Harmonic Balancer
MCE Engines Quick Tip Balancer Assessment Your engine's harmonic balancer is a shock absorber designed to take up crankshaft twist and rebound. As each cylinder fires and exerts its individual load on the crankshaft, there's a certain amount of torsional load where the crank twists and snaps back to center. The harmonic balancer, also known as a vibration damper, is an iron or steel hub wrapped inside a rubber ring inside an iron or steel ring. The rubber ring must be solid for the balancer to properly dampen shock and vibration. Examine your harmonic balancer's rubber ring. If it looks like the one on the right, replace it with a new M-6316-J351 balancer from Ford Racing Performance Parts (left). View Related Article
