I just rebuilt my 3.5 ton, Sears Craftsman jack... not quite as old as yours, but this video was very helpful. Especially where you mentioned noticing the tiny screens down in the base of the cylinder. Mine had two screens and they both fell out during disassembly, and I didn't know where they went. Still need to test my jack... fingers crossed.
Rare find - most of the suckers would say to just go to 'Horrible Fright'...I get condemned all the time. Same with car repair, bike repair, appliance repair...'the new one is 'just going to fail again' also. I've got a 1.5T floor jack that is nice and small but I've been longing for my old full size floor jack, but hesitating sending more money to China or Taiwan. I was give a 3T Craftsman 'that didn't work' (knowing I could fix it like you did, and I did before on that 1.5T Craftsman. I was viewing the 'rebuild kit' but figured I'd find that actual leak first. I added fluid but it still went limp after 24 hours. These have a check valve to adjust, it was too weak, tightened it up and cleaned and regreased (pulled those wheels, cleaned and greased the axles, and other pivot points) all and have a far better jack than the new ones.
Jerry I watched the whole video and you had the plunger right the first time. I went thru the same thing when I did mine forgot which way it was. So I took notice while you were doing it. Truly I don't think it matters it worked both ways with mine.
I also have one of these, bought it new in the 70s. Fast forward to 2023 got one of those overpriced gasket sets and rebuilt it. Well my kid was using it. Next time I go to use it, not working right. He some how snapped that u shaped metal piece that is welded to the top of that plunger shaft, right at the bend. I later found it out in the grass. I used that jack a lot for 50 plus years no problems. He destroyed it first time he used it. Never said a word to me, then denied he did it.
I learned that once the jack has lifted the item, use jack stands to hold the item up and don't leave the jack under pressure as that will lead to early failure of the seals. It's always something :😬
You are missing the ball/spring CAP and then a SPRING that goes in after the ball at 47:55; these two parts are correctly shown on the parts diagram. Not sure what these components do; appear to be some kind of pressure relief.
It is terribly lazy to say "RTV" when you mean silicone sealant. RTV could refer to any number of rubberlike compounds that do not require heating to cure.
Nice job Jerry.. A jack of all trades a master I'd say also. God bless..Very Entertaining..❤🌹
Great video and rebuild on the jack. Many thumbs up.
Very interesting. I have the same Sears floor jack which I also purchased 47 years ago.

Nice job Jerry, great little project.
Great work!

A good reason for videoing the disassembly so you can verify the parts on reassembly. That complex and uncommon number of parts makes that important.

I will often take a picture before disassembly .

Harbor freight has iron casters. Maybe one has the right wheel dimensions you can use if you take it apart.
I've a sneaking suspicion that you video jobs so you know which bits go where😂
On the lathe, slow down your speed for cutting hard material.
Politician wheel - - -goes from one side to the other 😅
FYI…….Easy Off Oven Cleaner is a GREAT degreaser. Use gloves

You need to get a life mate
I carved this residue out on my 2-ton and it was rubbery....
