Dayco Engine Harmonic Balancer P/N:PB1785N
Dayco PB1116N harmonic balancer for the 2004-2010 Ford F-150 V8 5.4L and other vehicles damps crankshaft vibration. This Dayco harmonic balancer sits on the front of the crankshaft, and its built-in pulley carries the serpentine belt.
Belt noise or vibration at the front of the engine can come from a worn balancer, but the belt, a tensioner or an idler pulley can produce them too. With the engine off and cool, look at the belt and at the balancer's outer ring for cracks before you order.
The 2004-2010 Ford F-150 V8 5.4L, the 2005-2014 Ford Expedition and the 2007-2016 Ford E-350 Super Duty V8 5.4L are among the vehicles this balancer fits. Each engine takes one, at the front of the crankshaft. If your vehicle is not named here, look up your own year, model and engine in the "Vehicles it fits" section.
