Harmonic Balancer Model A Harmonic Balancer discussion continued from earlier Thread. https://www.fordbarn.com/forum/showt...bration+damper
I felt I was high jacking this thread on Gear Backlash by continuing to ask questions on Engine Restorations LTD Harmonic Balancer so I started this new thread. From previous thread; Quote:

I received my harmonic balancer today. Nice piece. Weighs 5 - 5 1/2 lbs. Can I assume with the “reverse scroll” that a modern lip seal can not be used? I’m running a modern seal now. I did pose this question to Murray but have not heard back yet. I was just wondering if anyone on the Barn had experience with this. https://live.staticflickr.com/65535/...5c5deb1f2a.jpg https://live.staticflickr.com/65535/...52ebd521bd.jpg Thanks, Ruth |
Re: Harmonic Balancer From New Zealand. I've heard good reports but haven't had a chance to try mine yet. SOON though.

Re: Harmonic Balancer Yes from New Zealand. I just heard back from Murray. He confirmed to use the rope seals. It will be a bit before I can install mine also.
|
Re: Harmonic Balancer I contacted him also and had the same question regarding the spiral on the seal surface, but I have not asked if they are available without the spiral, as I want to run a modern seal in the front and a lip seal won't last long with the spiral.

Re: Harmonic Balancer I had not thought about the spiral on the seal surface either. I had wanted to run my Bill Stipes front seal that is on the car now.

Re: Harmonic Balancer So, it appears that were you to break a fan belt, you would have to remove the front pulley in order to replace it?

I am going to carry one of these belts with me 'just in case'. https://live.staticflickr.com/65535/...8b07b1b6_n.jpg |
Re: Harmonic Balancer I have a 31 tutor. I’ve changed a few fan belts in the past 20 years and I have enough clearance to change the belt without removing the pulley. Isn’t that the way it should be?

Re: Harmonic Balancer Quote:
These have a big advantage in that they do not flutter at high speed and cause vibration like a standard V belt. |
Re: Harmonic Balancer I'm running a modern seal with my harmonic balancer without problems or leaks.
|
Re: Harmonic Balancer They are available with or without the spiral so rope or modern seal compatible.
|
Re: Harmonic Balancer What are the benefits of this balancer. I probably missed it because I did not see earlier threads.

The heavier the damper/balancer or the lighter the flywheel/clutch assembly, the better. It has to do with reducing torsional vibration in the crank. You can't normally feel this vibration in the seat of the pants. |

Re: Harmonic Balancer I just wish it wasn't so RED! :rolleyes::rolleyes:

Re: Harmonic Balancer Most times when you lose a fan belt can't one just drive on home and replace it there. The thermo cycle should keep the water circulating and with common sense driving you should be okay. On a tour is a different story and carrying the industrial belt seems prudent if you have the harmonic balancer. That's what I will plan on doing if and when I get one installed. (Thinking of putting on and one of Snyder 6.? heads on the roadster. I is a little underpowered with the old Police head and 3:54 gears, though I can shift down and cure that, just have to drive slower.
