Attention: Read This Important BPE Pulley Information

BPE Reproduction Pulleys are stamped steel, just like the originals manufactured by Chrysler.

As in all Stamped Steel Pulleys, Including The Originals by Chrysler, Pulley Concentricity (Roundness)

May Vary .020” - .060” (Up to Approximately 1/16”). This Does Not Effect The Ability Of the

Pulley to Run True and Retain Its Belt Throughout the Power Band Of the Engine


This pulley is made up of two independent, dual-groove pulleys (just as the originals from Chrysler were made), which are held together for shipping purposes by three small spot welds in the center. These spot welds are not structurally important, they are only used to keep the pulley together for ease of installation. The centering hub on the harmonic damper, in conjunction with the six bolts attaching the pulley to the damper, are the only important structural items.

During installation, ensure that the pulley fits, flat, over the harmonic damper's centering hub. DO NOT DRAW UP PULLEY ONTO HARMONIC DAMPER WITH THE ATTACHING BOLTS. This may require removing excessive paint from damper, or deburring with a file. Upon installing pulley, if spot welds should be loose or not secure, simply re-align the holes in the pulleys, install onto damper, and torque the six factory 5/16" x 18 bolts attaching pulley to damper to 200 in. lbs. or (23 N*m).
