I have tried on this rig adding drivers to the piston using the bone rotation but the location of the piston is not consistent as the lever rounds the arc.( the rotation is consistent but the piston location is not and keep moving as i need it to slow).
I have before with success track to or locked track and that is what is on this rig but it does not keep up, If the movement is slow it will go to every pose correct but if the movement is quick it can keep up. (Move blender units per frame). In 3d view no problem but now it is a render problem and showed up in a animation.
Is there a fixable reason for the track to problem?
Is there a better way to rig this?
