[Torkmnstr]

No. I bought one from them and had to hone to fit it had a weird rib in the middle as well. Got it on but it was drama

Using their black one on my 383, no problems

Had the same problem.

I have one and it installed with no issues. Had it on and off once or twice. Presses on perfectly. People complaining about fit could very likely be blaming a crank problem on the balancer. Who's to say the crank is the right diameter !!

Tip: when installing the balancer, put some sealant in the keyway to prevent oil leaking out there. This is not an issue with the 440Source balancer, its just the way those parts fit.

I had to put a .120 spacer on the front of the dampener to get my lower pulley to line up with the water pump. Chrome one.

I know how to put a balancer on I've put hundreds on. Eagle cranks can be troublesome but the issue was the balancer not the crank. Do as you wish and I did get it on but it was drama.

You should have made a series for Discovery Channel ... they like drama !!

They are designed to be honed to fit if necessary. They come with instructions for doing so. I have used four of them without any problems. Measure, hone & install. If you don't have the tools, a machine shop does.

never had to do that on any engine I`ve built, be it hemi , 440, or chevy.

i always lube the press fit.

I ended up honing it and baking it at 450. Everyone has their trick and we all know as long as you don't beat the **** out of it you'll be fine. Some go right on some fight you. Just sharing my experience with the 440source one the dude asked about.

Two things come to mind. (1) If you have to heat a damper to install it......something is bad wrong. That is just not the way they are supposed to fit. And (2), 440 Source is one of the easiest places to deal with if you are having an issue with one of their products. I've had nothing but excellent customer service from them. Today being no exception.

I put one of these on a recently rebuilt engine rather than use the original vintage one.

The instruction said to heat it up in an oven which I did.
I understand it has to be an interference fit to function as a dampener.
I won't say it went on easy. But it went on with my home made installer.
To tell the truth, I wish I had save the money and used the original one.
I'm not racing.
But the specs on the new one seem tout some advantage over the old technology.

How do you hone something with a keyway in it ???

I've never had any problems with their customer service. I use tons of their products. Just had a difficult time installing the balancer. I don't make my living building these and right or wrong it's on now and has plenty of miles on it with zero issues.

I also had my weekends set aside, reserved to get the motor together and make the car run. I wasn't going to wait. Call 440source on a Monday wait for it to maybe show up on a Thursday and put me behind.

Again, my personal on hand experience with the dampener is that it was difficult to get on.

You use a stone wider than the keyway.

If they are honed to the proper .0005"-.0015" interference fit, you don't have to heat them.

And the Chevy, with that small damper bolt they have, I'm tempted to weld them on.

 

[vintage chromoly]

It's not unheard of to have to hone an aftermarket dampener.
This isn't soecific to 440 source.
It's part of the process when working with aftermarket pieces and stacking them up for fitment.

I understand, it was difficult to get on. By golly, if you want to heat it up, that is what I think you should do.
