Swapping engines

I opened a support ticket at LN, asking for assistance:

As per steps 41 and 42 of the Solution installation manual I installed the nut on the stud finger-tight, and then I torqued the flange bolts to 10Nm. Using a modified 3/8-drive 7/16" deep socket and a medium-large screwdriver I snugged up the nut on the stud. But now I'm scratching my head, because when I try to torque the nut, the stud turns with the nut. I had assumed snugging the nut would immobilize the stud so the nut could be torqued, but that wasn't the case. I tried tightening the nut more, with the same result. I have followed each step of the installation manual to the letter. How can I get that nut torqued?

Here's why I'm sure the nut and stud are spinning in unison. Note the registration marks. They don't move in relation to each other. Wish Jake Raby were here. No doubt he'd say something like, "I've seen this before, and here's what you need to do..."

LN Support's reply:

"The only advice I have is that some customers have used a small zip gun to quickly try and get the nut set and then use the wrench to torque it down."

I haven't replied to that. I wouldn't know what to say. This is a nutty situation, the latest in a string of nutty situations during this IMS bearing installation. It's true that this is new territory for me, and that's why I've been extra cautious in following LN's instructions, plus I've watched hours of videos demonstrating the process. I thought I understood every aspect before I began the installation. LN's support is not helpful. Looks like I'm on my own in solving this problem.

How is it possible for a nut on a rotating stud to "set" in the first place? It would seem to defy the laws of physics. The only possibility I can think of is that tightening the nut causes the other end of the stud, the part that looks like a valve, to press tightly against the bearing itself, limiting the stud's rotation. I've tried tightening the nut as much as is possible with the socket and screwdriver, and that doesn't seem to fix the problem. The nut and stud are still rotating together. I don't have a pneumatic zip gun at my disposal, but I have a powered ratchet. I guess I could try that. Funny, there's no mention of zip guns or problems with "setting" the nut in LN's instructions.

Doggone it, I have years of experience working on conventional engines, but it doesn't help me in this situation. It's humbling. If JFP or someone else with experience installing the Solution can't help me with this, I'm S.O.L. At least, for the moment.

Desperate, I opened a support ticket at flat6innovations.com in hopes Jake Raby himself would respond:

Dear Jake,

I've run into a problem installing a Solution, one LN's support couldn't help me with. I figured since you invented the Solution you'd know what to do. I'm having a problem getting the nut to "set" on the stud so that it can be torqued. The nut and stud rotate together, which makes torquing impossible. I described the situation in detail on 986 forum in my "Swapping engines" thread, in messages #396-398:

Contacting you here is a last resort.
