Used to install the lip seal on the freewheeling unit aft cap.
1.98in wide by .500 thick. Updated Manual says to make it .250 thick. We make it .500 because it is easier to manufacture and it also makes it easier for you to grip the work aid and pull it out of the aft seal once you are finished installing.
