Detailed Description

The Dayco PB1492N harmonic balancer is engineered for Ford applications that need a precise crankshaft damper and accessory pulley assembly in one component. Its hub-weighted design and cast iron outer ring help manage torsional vibration while maintaining stable belt drive operation. This makes it a practical replacement for worn or damaged balancers on Ford E-350 Club Wagon, E-350 Super Duty, Excursion, F-250 Super Duty, and F-350 Super Duty models, as well as select earlier Ford vans and trucks. This part cross-references Dorman 594-124 for the same application.
