<VV> Harmonic Balancer / Solid Pulley on 140

[Rodney Sampson]

I'd only use on an engine that's been balanced with the rest of the engine components.
When I send my motor out to be balanced, pulley, crank, pistons, rods and flywheel
  go.

Thanks

I picked  up my 140/manual that I am going to install in my 110/PG car and 
noticed the  harmonic balancer is probably on its last leg.  With cost in

pulling  has a solid pulley.  Thanks again, Joe



The extra cost of the harmonic balancer was warranted to protect the lower  
end from harmonic vibrations that could damage or destroy the crank and/or  
bearings according to my information.  My local Chevy dealer put a solid  
one on my '68 110 Monza 4 spd in the early '70s that I removed a few months  
later because I could feel a roughness when the engine was revved to the 
upper  RPMs.  The good, used harmonic balancer I got from a junk yard and  
installed cured the issue.  I later learned that GM's engineers specified  the 
harmonic balancer for this reason (as they did on other GM  engines).
