Take the crank off the shaft, now with your hands, feel if there is any **play** in the threads.

Wiggle it up and down, not in and out.

If there is any play, Loctite will not be able to bridge the gap in the threads to hold it.

Those cranks could be 50 years old, so it's very conceivable that the threads are blown out.

Time to call PBR.

Quoted from ChipS:

One last question: So now I'm torn between simply replacing the cranks ($10/each) and buying the complete rebuild set for 2 flippers ($50). Am I better off paying the extra $30 and rebuilding those two right flippers, rather than simply fixing the current problem?

Rebuild all the flippers.

The flippers are the interface between you and the game.

You will never know what the game is supposed to play like, until you play it with fresh flippers.

If you have a torque wrench, those older games say to put 75 pounds of torque on the flipper pawl bolts.

That's a lot.
