gtow69,
Don't throw out the baby with the jack oil! Hein-Werner might have made the hard pieces of the jack, but they sure as heck didn't make the seals, wipers and rings.
These old jacks are probably "inch" sizes and all the soft parts are available. There is a company called 'Seal Source' that has all these items listed by size.
If you are willing to do some legwork, these soft parts can be found. If there is a Applied Industrial, Dixie Bearing or King Bearing in your neck-o-the-woods, give them the cups, seals etc and let them earn their pay! Good luck.
