Harmonic balancer

On my 88 F-150 302 I just did the timing cover. Went to slide the harmonic balancer on, and it slid right on. No tool needed, and no effort. I bolted it on, and torqued it. Looked it up and someone said it needs to be thrown away, but that thread was on a new balancer. This one I’m dealing with is old. They said it can wear out the crank, just looking for some advice what to do. Thanks.
Sorry for posting a lot don’t know much about things like this.

If it has a woodruff key I would install it. If no key I would replace it.

Here’s a random photo off Google. That little notch at the bottom of the crank on this, mines got that. That’s a woodruff key right?

Heads up, aftermarket are almost all junk.

Damper Doctors rebuilds OE for a modest fee.

Guy on the Fordsix page had a Dorman slip almost instantly and begin to fall apart. I have been trying to find a spare for an EFI 4.9 to send out to rebuild as I really do not want to remove mine as the truck works.

Bought a Pioneer for my '88 302 truck. Fitment was sorely loose on crank snout.

The red 7.3 has a Fluidampr and works great. One would expect that considering its pricetag.

Hope it helps.

4.9? If so, ping me.

I have to pull mine as I am near certain I have coarse steel timing gears. Truck is so loud. Plus pan weeps and installing fresh pump.

You can use mine for Damper Doctor repair and send yours for me? I can deal with downtime.

Good luck to you.
