Lionel 282 clutch slipping

What voltage are you using for the Crane? It sounds like about 14V which should be fine. Obviously a too-low voltage would cause the solenoid to have insufficient pull to keep the clutch engaged.

I am using 14vac, so I do not think that is the issue. The same happens at lower voltages as well. 

Try adjusting the motor. It may be the armature is to close to the gear.

Watching the video it happens once a revolution of the winch shaft, at the same spot! Burr on the nylon gear? Bent winch shaft? Worn bearing allowing the nylon gear to spraddle away from the mating worm? The "bearing" is actually a shoulder on the underside of the nylon gear that fits into a counterbore in the cast base plate.

There is definitely something going on there. You can see the winch shaft move away from the worm/clutch shaft.
