Jogging My Memory
If you have the older style flat Jogger Links found on Model A and some other pinsetters, here is a tip about the Jogger Link bearings.
Sometimes the large bearing will become loose in the Jogger Link. If this happens, you can save the link by welding a steel spacer to the link and then cutting through the spacer and link. Insert a bolt with a washer, add a washer and Nylock nut and you now will be able to clamp the bearing in place.
