North Central Iowa, Humboldt County | I have a hdy. floor jack that no longer goes all the way up. It quits lifting and it seems to just have air instead of oil. I've taken it apart and there is no place to fill it with oil that i can see. The barrel of the jack has a rivet type plug instead of a threaded port. there is no plug on the base either. Is it possible to add oil to it by removing the plunger or the lock that you tighten to raise it. |
