how do i know if the harmonic balancer is weighted? i removed it to put on my march underdrive pulleys and i forgot to check the position of the original and just slapped it in. how can i cehck if the balancer is weighte? thanks

 

The balancer only bolts up one way to the hub, the 3 bolt pattern is not evenly spaced. The balancer is neutral but there may be some weights added; look in the machined holes that surround the outer diameter and see if any weights have been tapped into the holes.
