I decided I would try and do a write-up, with some pictures to try and show you how to do this. I searched and searched to try and find some pictures, to no avail. I will try my best to describe my process, it differed a little diffrent then ATI's instructions.

Here's what I started with. A hand full of "cobalt" 11/64" drill bits. Couldnt find any carbide bits locally. Then I got a hold of 2 "carbide" 3/16" drill bits. I used 2 bolts screwed into the collar that stick into the middle of the collar just long enough to touch the crank. They kept the collar from going to far into the timing cover when the balancer bolt was bolted on to hold the collar in place.




Firs things first, take old balancer off.


Then we did some measuring and taped off the drill bit to make sure we didnt drill to far into the crank. And the collar was installed with the 11/64" bushing. Tried drilling for about 5 minutes solid without even making a dent in the crank. By the way this is a forged Eagle crank! So out came the 11/64" bushing and went in the 3/16" bushing and a carbide 3/16" bit. Now were talking! Cut like butta!


Here was our home made drill press


Here is the dowel pin installed


Installing the new ATI balancer with my buddy's home made install tool lol


And fully installed...just wating for the 8rib pulley to be installed


Ok now I know this isnt really that hard, but kind of confusing as the instructions found online are a joke. Maybe someone will run across this one day and it will help!

SO DOES THE DOWEL PIN IN THE CRANK FIT IN TO THE KEYWAY IN THE BALANCER ?

your crank had a rough life prior to the pinning, by the look of it

yea, it looks like the crank pulley turned on the crank a couple of times

The ATI damper looks to have timing markings on it. Did you do any attempt to line these up to be accurate for TDC on #1 so they would be of any use?

blk00ss

iTrader: (66)

No I didn't try and line the timing marks up.

And I really don't know why the crank looks so rough in the pics. It's always been used in all motor applications. Never had a blower on it til now.

yeah man thanks for this, im to the point in my install of doing this and had so clue what to do lol.

why the tape for depth measurement? do you not just drill into the center(threaded portion) of the crank? the ati instructions didnt give any good depth information.

No the threaded part of the crank dosent start till about 3inches from the end. I pinned mine from the end but I would assume you wouldnt want to go too deep drilling because you would want the pin to bottom out on something solid and still be clear of the inside where the crank bolt goes in. Make sense???

blk00ss

iTrader: (66)

No you don't want to go into the middle of the crank because the pin needs to bottom out before it gets to the crank bolt. That's why I made this thread, because there isn't any instructions out there about this.

81cuttysupreme

oh boy. well i drilled mine all the way through the crank thinking that the pin depth would be designed to have the pin rest on the crank bolt. will the pin slide in too deep like this? any way to fix this, or do i need to drill another hole?

81cuttysupreme

would it be ok to just wrap some duct tape around the crank bolt to take up the diameter between the bolt and inside of the crank?

blk00ss

iTrader: (66)

Why not just drill another hole?

I'm sure no one doing this wants to hear this but that little pin sheared off on my setup with 850 miles on it. I'm not saying don't bother to pin it. I just hope the pin works for everyone else better than it did for me. It didn't look like my balancer had spun at all. The keyway was still lined up with the pin but the pin had sheared. I'm sure it would have caused problems later if the number 7 ring land wouldn't have given up so soon. I know there isn't many other options as I highly doubt anyone wants to pull the stock crank to have a keyway cut into it but that's the only way to do it right imo. Just some food for thought I guess. I know others have had better luck with the pins holding. I just don't have much faith in it after finding mine broken after putting 850 miles on it.
