Dayco Engine Harmonic Balancer P/N:PB1234N
Dayco PB1490DP harmonic balancer for the 1995-1999 Chevrolet Tahoe V8 6.5L and other vehicles damps the twisting vibration that builds up in the crankshaft. The Dayco PowerBond harmonic balancer is listed as a diesel performance race balancer.
Cracks or separation between the hub and the outer ring, or vibration at the front of the engine, can mean the harmonic balancer is worn, though a loose drive belt or a worn belt tensioner can be behind some of the same noise.
Besides the 1995-1999 Chevrolet Tahoe V8 6.5L, the vehicles it fits include the 1994-1998 Chevrolet C1500 V8 6.5L and the 1994-1998 Chevrolet K1500 V8 6.5L, along with many other Chevrolet and GMC models. Each takes one.
