We've got a NAPA 3T floor jack p/n 520-3003 which appears to have been mfg'd by Sunex (pix attached). We've had it... jeez, 20-25yrs maybe.
Lately it's started leaking oil and so it won't lift to full height. Of course we put more oil in it but it leaked out in no time.
Has anyone rebuilt a floor jack... is it reasonably straight-forward?
It appears a rebuild kit is available, but I know nothing about the quality of its parts. Heck, I know nothing about floor jacks but they can't be too complex.
I haven't looked at the cylinder closely to see if it's pitted / rusted, but just guessing I would say "not"... our shop stays reasonably dry, there's no salt tracked into it in the winter, and we leave the cylinder completely retracted (jack "down") when not in use. All the same, I need to check it.
(edit) I haven't checked YouBoob™ to see if anyone's posted a video on this particular jack.
