Title: harmonic balancers
Post by: 35chevcoupe on January 29, 2018, 10:21:31 PM

What are you guys doing for the harmonic balancers when rebuilding your nailheads ?  Just reinstalling the originals if they look good or getting them rebuilt ? or has anyone bought a new one ?   wondering how the new ones made , good quality or are they over seas junk .
Since I bought most of my engines in pieces I currently only have one used one and will be in need of at least one more .

I've heard of the rebuilding service... I think it was the DDr Mark mentioned.

There are aftermarket 455 dampeners that can be modified to fit. Likely not what you are looking for.

Or maybe I'm thinking of the Damper Dudes?

How does one know if they need to be rebuilt?  My engine was running fine when I tore it down and the balancer looked totally intact.  I simply blasted and repainted the balancer before I intstalled it.  Was that a mistake?  If so, it's easy to remove now before I put the core support and front end into the car.

Chuck , besides the obvious rubber deterioration i,m not quite sure except for maybe checking it with a degree wheel some how .

I had one on my Fireball 225 V6 that would slip.  It had a miss, after many hours of chasing distributor and wiring issues then struggling with the mighty single barrel carburetor.  I noticed when checking timing if I reved it a bit the timing mark would change positions. I drew a witness line across the damner with a felt tip and discovered the slippage. 
After that I’d set timing with a vacuum gauge. Now after discovering this service I’ll get it fixed.
Gosh, I love this site.

John,

  Found the balancers.  I have three that are for sale. I compared four balancers and all have the timing mark in the same spot in relation to the keyway.  My thought is that they are all good. I did notice that the dowels for balancing are not all in the same positions compared to each other.
 I also have crankshaft nuts and washers. Oil slinger if you need that as well.
