I rebuilt my Craftsman 9 50239 2-ton floor jack. I had to buy a 50mm socket and a 27mm wrench, but it was otherwise a straightforward affair. I can't imagine other floor jacks being much different. I wrote a DIY with pictures here: http://redeyegarage.com/blogs/news/8789897-red-eye-garage-tip-5-repairing-a-floor-jack (http://redeyegarage.com/blogs/news/8789897-red-eye-garage-tip-5-repairing-a-floor-jack).

In addition to your excellent tutorial, here are two more good threads on rebuilding and understanding import jacks: http://www.garagejournal.com/forum/showthread.php?t=51105 and http://www.garagejournal.com/forum/showthread.php?p=3068953#post3068953.
I have a Craftsman jack from the 80s (made in Japan) and it was leaking. I lost the data plate many years ago, but using the first thread I linked I was able to tear it down, clean, assemble, and adjust to operate correctly.
