Pioneer Automotive Industries Engine Harmonic Balancer P/N:DA-1786
Tame crankshaft torsional vibration and keep the accessory drive turning true with the Pioneer Automotive Industries Engine Harmonic Balancer (DA-3300). It installs as a direct-fit replacement on many late-1990s and early-2000s Ford and Lincoln trucks and vans, among them the 1997-2003 Ford F-150 and 1997-2001 Ford Expedition. See the Buyer's Guide tab for the full list.
A harmonic balancer mounts on the nose of the crankshaft, where a rubber ring between the inner hub and the outer inertia mass absorbs the engine's torsional pulses and helps keep the accessory belt tracking smoothly.
If a cracked, separated, or wobbling original balancer is behind belt vibration or a slipping crank pulley, this replaces it.
