My Dad has a 2 ton AUSCO floor jack from the 1960s. AUSCO closed and started up under the name US Jack
It leaks fluid out of the ram but I don't know who sells seals that would fit it. Does anyone know who sells the needed seals?
have you contacted US Jack? what types of seals are they? o-rings? lip seals? leather? if you are lucky they used standard off the shelf seals.
they list a service center in south bend on main st. have you contacted them?
