Ford Stroker Pulley Alignment: Pulley Spacers May Be Required

BluePrint Engine Tech Tip: Issues with accessory drive pulley misalignment on Ford Stroker engines may require the installation of a pulley spacer on the harmonic balancer. Spacers are available from several commercial sources.

CATEGORY

ISSUE

In some applications, accessory belts (alternator, power steering) may not align with the harmonic balancer pulley during assembly. This problem can be corrected by installing a pulley spacer on the harmonic balancer.

DIAGNOSIS

Select the correct thickness by using a straight edge from the accessory pulley to the harmonic balancer, ensuring that the straight edge is parallel to the engine front cover. Measure the misalignment from the center of the harmonic balancer pulley groove.
