<VV> Harmonic Balancer

[Andy Clark]

Excellent question, Dave. I was wondering the same the thing.
The urethane seems stiffer than the rubber. How much does this change the
natural damping frequency? And are we living under a false sense of security
with the stiffer urethane and therefore a higher damping frequency?

At the risk of continuing to beat a very dead horse, I have a technical
question.  What is the dampening characteristic of the rebuilt balancers
-- e.g., Dale?  Do they duplicate the original frequency attenuation
characteristics or is the rubber simply replaced with urethane?
