ATI Harmonic Balancer: Honing to Fit Stock Crankshaft

[Nxcoupe]

This is how I had to take the one off Krusty's crankshaft...
Great job by my builder.

Why?

It wasn't coming off. All 3 bolts snapped in the puller. Sounded like a gunshot, and two hit me in the leg.

Did you use them on 440 with stock crank pulley?

Yep.

Thanks for the part number!
I checked Summit ATI Performance Products ATI917470E ATI Super Damper Standard Harmonic Balancers | Summit Racing
No problem with price.
What did you put in keyway to use wheel cylinder hone?
Also, the reviews site problems with the T-40 Torx pulley attaching bolts. I have the socket tool. Did you have any issues with these bolts?

I used a wheel cylinder hone and a little piece of paint stirring stick. Sometimes I had to hone, sometimes I didn’t, across several brands.

I had an older Fluidampener that was a son-of-a-gun to install. I chucked it up in a lathe and genty emory clothed it till it was easier to install.

Roughly 5 minutes of total run time on the lathe.
