Off Center Harmonic Balancer?

1994 F150 302 5.0

Just finished timing cover and gasket job.

Is it just my eyes playing tricks due to the uneven shape of the balancer or does the harmonic balancer appear wobbly?

Note in the video below the crankshaft pulley does not wobble, if the balancer is indeed wobbly the pulley should wobble too?

I did ensure the balancer was installed into the notch on the crankshaft.

To me, it appears the camera holder is wobly, the video frame wobbles and looks like the engine block wobbles.
I'd say its just our eyes playing tricks.

Not wobbly.

If you focus on the full round sections, like back in where it tapers down near the seal, and out front where it's smooth all around, you can see that compared to the fixed objects in view that there is no wobble. The non-round sections are causing the eye to say wobble...

You can also take length of coat hanger, make a crook & put it under a bolt head.

Then bend the point out to an edge of the balancer, about a 16th of an inch gap.

I'd use a stud on the timing cover to bolt it down with. Should show real quick if there's any out-of-round or wobble.

Or bent crank snout.

I figured it was an eye trick. Tested my increasing throttle in park and again during a road test felt smooth no odd vibrations to note. Also watching the crank pulley from all angles, it rotated as should with no variances left right up or down.

Happy that I saved $1500 in doing the timing chain and cover myself!

Thanks guys👍🏻

If it was wobbling, you would feel it. And if you only had the truck a few months, and the previous person that replaced the timing chain last didn't torque the bolt properly, and the bolt works loose and the balancer wiggles loose and you're driving down the Interstate and you hear a fwap-fwap-fwap noise, well, it's not a broken fan belt. It's a broken crankshaft. Ahhh, good times.
