How ATI RECOMMENDS you install their damper

IvanK · Apr 21, 2017

There has been ALOT of questions about this lately.. So we worked with JC @ ATI Performance and came up with this article. It will also be on their website to view. Up until now there has been limited information about proper installation. The job isnt complicated but it does require the use of proper tools. With the right tools its simple. Hope you guys find it useful! :cheers:

Interesting. I had a hell of a time getting mine seated all the way on a fresh build, is freezing the damper recommended before install? or warming it?

Don't need it now, but I might replace my crank seal sometime, and hadn't had enough coffee to think through the process.

Warming the balancer will expand it slightly. Be careful not to get too hot as can damage the internals.

If you are going to heat it. I recommend you heat only the hub. Get it nice and hot in an oven or something that will heat evenly. Then install quickly. Once the hub is seated you can let it cool and assemble the rest of the Damper. Oh and dont forget the inner ring goes on before you press the hub on! lol

Locking flywheel?

They didnt mention locking the flywheel for the 6R80 peeps?

There are a few ways of getting the damper bolt torqued down. Didnt find it too necessary to mention them all. You know how it is.. If you mention one then someone will say well you could have done it this way too. LOL

Hope the information was helpful though!

Serious question:
Why have an interference fit if you are going to use anti seize which contains grease?
It seems this would focus all the torque transfer on key and keyway and since the ATI keyway is cut overwide... you would risk ratcheting the lash out of the key to key way fit?
I cleaned everything with brake cleaner and compressed air with front cover off to insure no sealant back in pan and inspect key way. Replaced key cause stock had a high spot.
Installed only AC pulley to ATI hub and heated to 210 in oven for 1 beer (10 min).
Only added RTV to ATI keyway and installed with B7 200mm stud/rod with a 10.9 nut.
Have also used 130mm bolt from fastenal w increasing washer stack. Just always count turns and stop at 15.5 cause a hair over 16 bottoms out.
All threads clean dry and torqued an ARP. bolt to 120 ftlb.
While red threadlocker may stop bolt from spinning, it wont stop damper from lashing on the crank if the ATI keyway is oversize.
I lock the crank w a soft AL tooth lock that bolts to bell housing; however, I use a strap wrench to make sure the key is loaded against keyway for driving supercharger as I start tightening down so no lash at least on driving SC.

But back to question, why grease an interference fit and decrease its torque holding before it lashes keyway?

When I installed mine I did it the same way I've installed hundreds of them over the years. Just as you said I instsllled it dry til it seated except I used a homemade stud to engage all the crank threads for pulling, applied a little Ultra Black to the key, and torqued down the ARP bolt with ARP lube. On a side note I double checked the torque on my bolt after a few thousand miles and it hasn't moved. Properly installed they can't loosen.
