@@graybeardgarage9638If you don't know by know, Your Sears floor jack is a 9-50115. The plunger o-ring is a 3.5x15 trade size. (3.5 dia. X 15mm ID and 22mm OD) My backer ring or the plunger o-ring was missing from the factory(found a exploded diagram online) If you can leave the plunger wiper seal in, do so. They are expensive. As for the main cylinder there are two versions, 42mm(v1) and 40mm(v2). Just measure the CD(diameter) of the o-rings you need to replace. When I get to that point if you still have the jack, I can compare and share the trade sizes of the parts.
