Installation, Accessory drives
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.
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.
Pulley spacers are available from several commercial sources, one being Professional Products.
Spacers are available in the following sizes:
Ford 347 (all)
Ford 331 (all)
BP3474CT, BP3474CTC, BPF3474CTF
