Every 6 months I have to retighten the cone screw on the shifter. This time it came out real quick. I thought it might come out all together. I couldn't get 2nd without hitting reverse. The picture shows how much the screw backed out.

Not sure how much torque I applied but I was bending the allen wrench.

Questions:

Should I have thread locker on this?

What is the torque required for the cone screw?

Possible that the threads have been widened by repeated looseness?

Why didn't they put a bolt through this to really lock the hub onto the shaft?


TIA
