This is the cause of my rattle. Which is a relief, but also a different part to stress on. I pulled it all apart and decided to use the shorter set of 3/8 bolts that came with my crank support kit because they actually bolt to the balancer hub whilst the longer ones go through the hub and end threading into the ac pulley. Anyway got it all back together and fired it up and the rattle is gone, but the blower pulley has a good vibration to it now. I called procharger and they said I should be using the longer bolts and that it is supposed to bolt to the ac pulley. Anyway after it cools down a bit I’ll probably go out side and have another go at it. Getting a little frustrating though.

On the twin cam Harley engines the service procedure for tightening the oil pump was to snug it then spin the motor several revolutions. Doing this would center the gears. I believe I would also use this method on the coyote.
HD has some major run out on the crank.

Holy smokes that was loose AF.

Yeah. It’s really odd. Using the supplied 2&3/4 inch bolts that came with the cs they won’t pull the pulley tight to the balancer. Almost like the bolts are too long. But now that I’m using the shorter bolts and the other 3 bolt holes the pulley and the mandrel wobble. I’m going to pull it apart again and very closely examine things. There’s got to be something I’m missing

Figured it all out! I was going back through the crank support instructions and I noticed in the pictures there was no additional bolts in the balancer. I’m referring to the 3/8 12 point bolts . I had the ati supplied bolts holding the ac pulley on and then the bolts that came with the crank support holding the blower pulley and mandrel, but this is incorrect. The 12 point bolts go through the stage 2 pulley but do not allow the mandrel to fully seat. I ended up installing the blower pulley and mandrel with the longer bolts that are supplied with the cs kit. They go through the balancer and hub and end threading into the a/c pulley. All problems solved! Car runs great!

Hmm, our kits must be different. My blower pulley and mandrel thread into the ATI damper hub and not the ac pulley. I have separate bolts holding the ac pulley on that the blower pulley straddles.

If you have some pictures of your install I would love to see them. I tried it the way you mentioned and the bolts protrude through my pulley not letting the flat surface of the mandrel sit flush. I’m pretty sure the instructions for the ati balancer say not to leave any hole with out a bolt, but I don’t see another way. I also talked to a tech support guy at procharger and he said that the bolts going to the ac pulley was correct, though he didn’t sound terribly convincing

This is how mine is configured as well.

That way makes sense to me which is why I tried it twice, but with hardware supplied in both the cs kit and the ati balancer it just won’t work. Even if I took the washers off of the ac pulley bolts that come with the balancer they would still be too long. I’m hoping that perhaps the cs I have is different and that everything is correct with the assembly. I’ll probably reach out to procharger again to see what a different tech support person says

Did you happen to google boundary oil pump gear noise? MMR might not be the only one having this issue.

The bolts in my kit didnt work out either. I used the 12pt bolts that come with the balancer to fasten the AC pulley. Then i shortened the 6pt hex bolts that come with the CS to fasten the mandrel/blower drive to the threaded holes in the steel balancer hub. Those needed to he shortened because they would bottom out into the face of the AC pulley and not tighten up blower drive, like in your video.
I assume Procharger intended the 6pt hex bolts included in the CS kit would fasten the mandrel/blower drive, through the unthreaded holes in balancer, and thread into AC pulley. I didn't like that as the threads in the aluminum AC pulley would fatigue over time (torquing the bolts all the time cause i take shit on and off alot).

This makes sense. I thought about modifying their bolts or just sourcing my own. For the parts I have if I use the ati supplied 12 point bolts for the ac pulley the cs mandrel will not sit flush on the face of the blower pulley. I may end up sourcing my own 3/8x16 flange headed 6 point bolts for the ac pulley and to bolt the blower pulley/mandrel to the balancer hub. I think a 6point bolt will have a low enough profile to not interfere with the mating surface of the mandrel and I think a flange head will fit into the holes on the blower pulley. Now I’m just wondering how many times I can pull this crank support on and off before I need to replace the bearing. It’s a pretty snug fit

Bolts for ac pulley, they go thru the non-threaded holes of the damper hub:
Bolts for the mandrel and blower pulley, they thread into the damper hub:
Looks like this:
I have reversed the bolts and it didn't have any issues either.

Very interesting. This is how I set it up first time around and it wouldn’t work. The cs mandrel would rest on the bolt heads. The bolts I have for the ac pulley can’t have the washers removed at least not without cutting them off.
Right now the mandrel and the blower pulley are theaded into the ac pulley and the other three holes that thread into the balancer hub are empty which I’m a little concerned about because the ati instructions seemed pretty adamant that no holes be left without a bolt, but I believe this is what procharger intends. I sent a DM to @ProChargerTECH seeking some clarity on their instructions, but I have not heard back yet. I may end up sourcing my own bolts and bolting it up the way it seems most others have done as this seems to make the most sense.
