AARRG! Did I strip my crank?

So I was torquing my flywheel yesterday in three increments, 15, 30, and 45. That's from the book. But I was using my 3/8th Torque Wrench, and it maxes at 75. Still, it's within its range.

Just as I was torquing the last bolt I was thinking "This seems like a lot of torque, why hasn't the wrench clicked?", it got easier to turn. Fearing I stripped something, I stopped.

When I backed the bolt out, it looked fine. But I set it aside and got a completely new set.

I took the flywheel off, ran a bolt through that hole in the crank with my electric impact lightly. It took a little force compared to a new hole, but it went in and out without incident.

So I put the flywheel back on, used new bolts. I wasn't sure if that one hole was going to hold 75 ft/lbs so I used red loctite and stopped at 45.

I probably need to go out and redo it to 75 and take my lumps, but I'm scared.

Will 45 ftlbs and red loctite hold it forever, or should I take it to 75 and get the crank repaired if needed?
