What are uall using to hone-out the crankshaft hub. on your ATI dampeners. So that they will have a better fit on the crankshafts....Thax.

My ATI didn`t need it on a stock crank but I had Pettis hone my Fluidampr...............

I used a piece of 3/8 tubing with a slit in it and put
400 grit paper on it... rapped it around the tube till
it was fairly big then put it in a drill motor...
that was before I had a lathe

I used a brake cylinder hone when I did my damper. also you can use a small ball hone. places like enco and kbctools etc sell them.

Brake hone is the best way. Make a wooden key to fit in the slot on the damper so u don't break the stones.

Decide how big you want it.........take it to your local shop and have them do it on a rod machine. It will be done before you can jury rig something.......plus it will be straight

Sunnen makes a keyway mandrel for that, I had to do mine. The book spec is .0005" to .0015" interference with .001" preferred. If you don't have equipment that reads in tenths, take your crank and balancer to the machine shop and have them hone it.

Rod hone does it quick and easy.

Stuck mine in a 350 oven for a couple of hours, it went on with just a mild push plus a couple of taps.

One could probably do that with a factory balancer on a factory crank , but aftermarket balancer , and a crank made by a diifferent company , I wouldn't bet on it .

I have put them in water and boiled it for a few minutes to get enough
expansion to get it on. I mentioned that to Fluidamper and they said that was probably OK, they just had never thought of it.

What about getting it off though , heat or just sign of the cross and hope for the best ?
I have a magnetic bearing heater at work so I can get it up to 300-350 pretty effortlessly ...

Re: Hub. honeing - 12/16/14 02:37 AM
What you CAN do and what you SHOULD do are two totally different things. A certain amount of press is required. If you heat the thing hot enough, you can likely get it on even when the tolerance is way tight...........BUT, then you got to get it off at some point. If it is way tight, there are several scenarios. One you destroy a puller trying to get it off. Two, you drag metal out of the hub, or off the crank. One means you need a new hub. The other means you destroy the end of the crank. Sure, you can polish it off, but then you have drag marks and missing metal in hub or on crank snout. At that point the press is NEVER right, because you have incorrect surface area.
So.......WHAT TO DO?..........Check it..........fix it RIGHT

I just installed my new ATI balancer. Measured the crank and the inside diameter of the hub, had it honed on a Sunnen rod machine. ATI says to use anti seize on the hub. If you get it to tight, good luck getting it off. Dyno

Never had any problem getting them off using high pressure grease when installed. I'm not talking expanding it .005"+,,just maybe .001" or less with the 212* water heat. Just enough to go on easier with normal resistance than what it felt cold.

I heated the last SFI dampener up on my shop wood heating stove to 130F and it tapped on real nicely, I did use Permatex brand silver antiseize on the crank snout and in the dampener hub so it will come off eaiser than without it. I'm sure some of us who have worked on stock BB Chevy have thought we would break the dang puller before getting those dampeners off 
Most Mopars are a breeze to remove compared to them turds

And you can get press fit specs from the manufacturer and take the crank with to measure. Press fit is important for the damper to do its job.

Your original post made it sound like you took a balancer that would not fit because of size and you heated to get it to expand and pressed it on ???
