Is an original harmonic dampener rebuildable? I have one that the inner machined piece that contacts the seal has cracked and someone attempted to weld it back to the flange. There's no way I trust this, and wonder if anyone has attempted to press the inner piece out, and press a new one in? Is the rubber material that separates the inner piece from the outer available?

There are companies that can re vulcanize those, you could probably do a search...

Tom’s balancer is unique and as rare as hens teeth, a balancer rebuilding expert is the only choice.

Your balancer is a dime a dozen that’s readily reproduced and available new.

I called another balancer rebuilder that Tom had recommended because I had a 421 balancer I wanted rebuilt. This same balancer was used on all non-SD ‘59 -‘67 V8 and 4-cylinder engines, dime a dozen. I called and he told me they don’t rebuild them anymore and he simply sold me a new one, he’s the same supplier for all the reproduction balancers sold by the aftermarket.

Buy new.

Actually, I have the same one that Tom does.

Looks like Tom has you covered then.

At a glance it looked like a common balancer.

Not a problem. I was trying to show the crappy repair on it. Honestly, I might still use an aftermarket item if this it too expensive to repair. I want to try to keep it original looking, but perfectly willing to use other parts - especially if it improves the reliability.

Tom, I'm curious, did your RAV dampener fail like mine, or were you having it rebuilt proactively? Unfortunately, I don't know the story behind this failure - whether it was jacked on or failed during racing. I'm just suspicious the center hub is not strong enough to handle the increased weight.

Very interesting. Perhaps these hubs really aren't strong enough to handle the extra weight. I was planning to send a good factory hub with mine as well.
