This is obviously the "old" style caster.
The newer style casters also use the roll pins on each end to hold the "assembly" together. The "upgrade" is the addition of a flat head screw in each end of the shaft that the cams are on. The screws go through the end castings into their respective ends of the shaft. See the picture in my previous post.

If you have the newer castings, either the screw is missing or it has sheared off. I am not sure this is a better design than the old style casters. If you have the older style casters then you might try flipping your machine and check to see if the legs have become bent or distorted. If this is the cast then the legs will need to be "reshaped".
Remember to do this regardless of which 'version' you have!;)

I think you've found the problem. On one end of the shaft, the screw is missing; on th eother, there is a broken screw (%$#%) in there that I need to extract somehow. I'll work on that tonight.
This probably explains why it worked well for quite a while then once it failed, it repeatedly fails.

I be curious WHY after all these decades(3 score!) without a 'retaining screw' the camshaft has this 'issue'.
Is the shaft shorter???? Is its socket shallower????

I find these replies very interesting. a couple of years ago I acquired a used power stand. Recently I decided to add the caster set. Shopsmith had them available. Upon receipt I installed them and discover one would not stay in place (consistently fell out). The gentleman at Shopsmith suggest I switch the positions from one side to the other to determine it wasn't the housing. It was the caster itself and the replacement cured the situation. fjimp

I managed to extract the broken screw from the axel rod and replaced the rod in the carriers with new screws. Seems stable now.

Check with Ed in Tampa. I bet he has the exact replacement screw for the caster.

Good to hear, those screws are not very big and can be a pain to remove the remnants from the hole.
