Not sure if this explains or not. How much did you apply. Doesn't take much so you should have applied enough.
Were the threads free of greas and oil before you applied it? Try cleaning everything with Contact Cleaner or Brake Cleaner and try again.

I don't think there is really a set time. I've read about people that let it stand a day or so and others that did the fix, topped off the oil and coolant and took off. I personally let mine stand a full day before I put oil and coolant back in it......

Were you using Loctite brand thread locker or another brand? Not really a problem either way unless it was some Harbor Freight imitation.
What torque is torque to spec?
What did you use to clean parts?
Loctite seals and bonds the threads. It is hard to say what you should see for break-a-way torque. I would expect to find it higher than assy.
Did you find red power or other residue on the threads?
You can degrease the screws but not very good on the threaded holes. This will reduce the effectiveness of the Loctite. But not to worry, even Loctite says it still has some affect on oily parts.
Use commonly available hi-strength "red". As you see, it is not all that permanent.
Loctite says you can add oil and put back into service right away, but I feel better with a 24 hr cure.
Thread lockers are anaerobic. Depending on product they need a restricted space to cure. Most products are less than .005 space to cure. Less space for best bond.
Are you stator screws zinc plated? (silvery color) If so, discard and go buy some grade 10.9 or 12.9 replacements that are black (black oxide). (Heads are marked with strength). With Zinc screws, a primer may be needed plus the zinc is an anti-seize

The original stator screws are 10.9. With grade 10.9 you can use 100 inch pounds. If you go with grade 12.9, you can use 120 inch pounds. As you probably know, the torque spec given in the manual is wrong so you are kind of on your own to determine the correct torque. The above numbers are conservative and work fine. 84 in lb is for grade 8.8 screws. Most of the time I recommend go light on torques but with the stator you want to use the full value.
I forgot to ask about temp. Temp does have an affect on cure time. It would be good if the temp of the parts was at least above 50 deg for a 24 hr cure. 70 deg would be better.
