As mentioned, an additive such as Maxglide or the product Cat Oil (Caterpillar trade name) which works to free up the binding properties of hard or tight packing can be used. However, I’ve seen instances where two or more bottles of a additive were used but the hard breakaway remained. Time for jackhead seal replacement. “The better the effort,the better the result”. Repacking or new seals; I’m not sure if you’re a licensed elevator, lift LULA tech, but if not, you’ll need to leave this work to a licensed elevator/lift contractor. And prying the wiper back to pour a product below the wiper ring means you’ll need to be under the unit, in the pit to do this. Again, “the better the effort…” is an appropriate reminder.
