This is one of the best tips I have to help you keep your new style tongs working. If they are dropping pins and you have exhausted all other tune up methods I have posted in other videos, then this is a must watch. This only works if you follow critical details. Don't rush this rebuild, you'll regret it. Try one lane at a time. Test it out. We have been running it in a location currently for over two years. Now we are in the process of rebuilding another house, but only as needed on trouble lanes. If the links become loose again, tighten the lock nuts or replace them.
