Pedal separates from shaft
Right side pedal keeps separating itself from the axle.
First occurrence was perhaps 200 km ago, at which time I disassembled, cleaned and greased and tightened with a wrench. During a ride yesterday, it again came apart again. Thankfully I was seated at the time. Without tools on hand, I finger tightened and went on my way. During the 40 km ride home, it unscrewed itself four times - naturally I was sure to stay seated. I cannot imagine standing when this lets go.
Note that the pedal axle remains firmly attached the crank arms. The issue is the right side pedal unscrews itself from the pedal axle. These are vintage Look pedals,
Does anyone have a suggestion on how to resolve this?

Take it fully apart and make sure the bearings spin right, only reason I think it should happen is too much friction allowing the fixing bolt to move. Use loctite to reassemble when you screw it all back together. If its old I'd just replace the bearings in case they're being allowed to spin or have deformed and check to make sure the axle is straight.

There is a cir-clip behind the bearing that needs to be removed. I haven't ridden a Look pedal since my right one broke cleanly at the grove causing me to flip. The groove is a stress-riser.

I took the pedals to the local bike shop to have a look. In the end, I purchased some new Look Keo 2 Max. I did not want to play around with nearly 30 year old pedals. The shop did not either, as there is some binding/mild cross threading going on with body and the part attached to the axle. I want to get back safely on the road asap.
I very much appreciate the help here.
