Dayco Engine Harmonic Balancer P/N:PB1297N

Description

Tame crankshaft vibration and keep the accessory drive spinning true with the Dayco Engine Harmonic Balancer PB1297N. This crankshaft-mounted damper drops in as a direct-fit replacement for the 1988-1995 Toyota 4Runner, the 1988-1995 Toyota Pickup, and the 1993-1994 Toyota T100.

Torsional vibration control: designed to absorb and dampen the crankshaft's twisting pulses so engine speeds run smoother.
Accessory belt tracking: its pulley surface guides the engine-belt-driven accessories, helping keep the belt aligned and running quietly.
Direct-fit replacement: built to install on the listed Toyota applications without modification.

The harmonic balancer bolts to the nose of the crankshaft and works constantly to counter the vibration created as the cylinders fire. Over time the damper element can deteriorate, letting the outer ring shift or wobble. Signs it may need replacing include engine vibration, a visibly slipping or off-center pulley, belt squeal or misalignment, and timing marks that appear to move. If a failed balancer is the cause of those symptoms, this PB1297N replaces it. Diagnose the source of any vibration before installing.
